Highcharts combination chart from JSON data

I am creating a combination chart taking data from a database. I am able to import all the data and render it in single type i.e. Column. There is one series though which I want to render in spline type. The tutorial I am following only teaches about rendering in a single type, so I am kind of lost here.
This is my JavaScript
$(document).ready(function(){
var options = {
chart: {
renderTo: 'fetch-render',
type: 'column',
},
xAxis: {
title: {
text: 'Date'
},
categories: []
},
yAxis: {
title: {
text: 'Number'
},
series: []
}
$.getJSON("includes/fetch-data.php", function(json) {
options.xAxis.categories = json[0]['data'];
options.series[0] = json[1];
options.series[1] = json[2];
/*so on...... */
options.series[7] = json[8];
/* i want to draw this series in spline */
options.series[8] = json[9];
chart = new Highcharts.Chart(options);
});
})
I want to draw data from series 8 as a spline unlike others which are drawn in column type

Highcharts Demos have all kinds of demos of using Highcharts. One of them shows how to draw different types of series in the same chart: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/combo/
Basically, instead of defining the type on the chart object like you did, you will set the type for each series on your series object:
series: [{
type: 'column',
name: 'Jane',
data: [3, 2, 1, 3, 4]
}, {
type: 'column',
name: 'John',
data: [2, 3, 5, 7, 6]
}, {
type: 'column',
name: 'Joe',
data: [4, 3, 3, 9, 0]
}, {
type: 'spline',
name: 'Average',
data: [3, 2.67, 3, 6.33, 3.33],
marker: {
lineWidth: 2,
lineColor: Highcharts.getOptions().colors[3],
fillColor: 'white'
}
}

Thanks for the heads up by #João Menighin . i adopted the method given in this demo. its neater, cleaner and can be used to add as many chart types as needed. here is the code for someone else who wants to make a combined chart taking data from the database.
$(document).ready(function(){
$.getJSON("includes/fetch-data.php", function(json){
Highcharts.chart('fetch-render', {
title: {
text: 'Fetched Data'
},
xAxis: {
categories: json[0]['data']
},
series: [{
type: json[1]['type'],
name: json[1]['name'],
data: json[1]['data']
}, {
type: json[2]['type'],
name: json[2]['name'],
data: json[2]['data']
}, {
type: json[3]['type'],
name: json[3]['name'],
data: json[3]['data']
},{
type: json[4]['type'],
name: json[4]['name'],
data: json[4]['data']
}, {
type: json[5]['type'],
name: json[5]['name'],
data: json[5]['data']
}, {
type: json[6]['type'],
name: json[6]['name'],
data: json[6]['data']
}, {
type: json[7]['type'],
name: json[7]['name'],
data: json[7]['data']
},{
type: json[8]['type'],
name: json[8]['name'],
data: json[8]['data']
},{
type: json[9]['type'],
name: json[9]['name'],
data: json[9]['data']
}],
});
})
})
And i have set the chart types in fetch-data.php like this
$date = array();
$date['name'] = 'Date';
$blank=array();
$blank['name'] = 'Blank';
$blank['type'] = 'column';
$direct=array();
$direct['name'] = 'Direct';
$direct['type'] = 'area';
$checked_in=array();
$checked_in['name'] = 'Checked In';
$checked_in['type'] = 'column';
$conf=array();
$conf['name'] = 'Conf';
$conf['type'] = 'column';
$gdf=array();
$gdf['name'] = 'GDF';
$gdf['type'] = 'column';
$gdp=array();
$gdp['name'] = 'GDP';
$gdp['type'] = 'column';
$gtn=array();
$gtn['name'] = 'GTN';
$gtn['type'] = 'column';
$prov=array();
$prov['name'] = 'PROV';
$prov['type'] = 'column';
$enquire=array();
$enquire['name'] = 'ENQUIRE';
$enquire['type'] = 'spline';

Have an issue with JavaScript, AJAX code displaying data

I need some tips from you out there to come over a good solution on my problem with JavaScript, AJAX and JSON data. I want to fill a generic set with barcharts (I am using HighCharts) on my web page. The data is in JSON format which from the start I only used date and value as pair data set. The solution works fine of I had only one bar chart it, but I have a lot of charts on my page and I need to show all of them (up to twelve).
Now I want to adjust for displaying more than one graph. In the code below the DataMacro array works fine with the chart. It also has a hard coded ID matching a . Now I have a series of in the page like id=barchart11, id=barchar21, and so on. In the dataset I have made a tag called PanelCodeUI that I am going to use looping through the dataset. The problem is how to do that. The each-loop will now fill in all date,value for all vessels.
And further it I need to restructure the function which is displaying the barchart. The best thing would be to call a function with a data array and panelCodeUI id just replacing the name of the barchart and set in the datamacro as is. But I don’t know how to do this. The data is mixed between all vessels and I need to collect all data before sending to a function. So is the problem with AJAX and JavaScript with is asynchron. I need to ensure that it behaves correctly and fast.
Maybe I need to change my dataset, or I need to do this in several step like finding all vessel IDs then do another AJAX call to get date,value pair from a vessel and then displaying. I hope there is a way to do this with this data set and hope somebody can help me on this
Here is a bit of the JSON data set:
[
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":844,"VesselId":1,"SectorId":2,"PanelCodeUI":"21","VesselCodeUI":"21","VesselSorting":1},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":8720,"VesselId":4,"SectorId":1,"PanelCodeUI":"11","VesselCodeUI":"12","VesselSorting":2},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":948,"VesselId":5,"SectorId":1,"PanelCodeUI":"11","VesselCodeUI":"11","VesselSorting":1},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":0,"VesselId":6,"SectorId":3,"PanelCodeUI":"31","VesselCodeUI":"31","VesselSorting":1},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465171200000,"Value":2067,"VesselId":1,"SectorId":2,"PanelCodeUI":"21","VesselCodeUI":"21","VesselSorting":1}
]
And here is the JavaScript code so far:
$(function () {
var datamacro = [];
$.ajax({
type: "POST",
url: '../Services/HighChartService.asmx/GetOilProductionLast5DaysByActiveVessels',
data: '',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (seriedata) {
console.log(JSON.stringify(seriedata.d));
var productions = seriedata.d;
$.each(productions, function (index, productions) {
var yval = productions.Value;
var xval = productions.Date;
var x = [xval, yval];
datamacro.push(x);
//alert("productions Name: " + productions.Date + "\nID: " + productions.Value);
});
$(function () {
//var bchart = '#barchart' + vesselindex.toString();
// want this to be looped with generic names like #barchart11, #barchart21, #barchart31 and so on
$('#barchart11').highcharts({
chart: {
type: 'column'
},
title: {
text: 'LAST FIVE DAYS'
},
subtitle: {
text: ''
},
xAxis: {
type: "datetime",
tickInterval: 24 * 3600 * 1000,
labels: {
rotation: -45,
align: 'right'
},
dateTimeLabelFormats: { // don't display the dummy year
day: '%e. %b',
},
//crosshair: true
},
credits: {
enabled: false
},
yAxis: {
labels: {
enabled: false
},
title: {
text: null
}
},
tooltip: {
formatter: function () {
return Highcharts.dateFormat('%d/%m/%Y', new Date(this.x)) + '<br/>' + ' in barrels: ' + this.y;
}
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}, series: {
pointRange: 24 * 3600 * 1000, // one day
pointInterval: 3600 * 1000
}
},
series: [{
//name: '',
showInLegend: false,
data: datamacro,
dataLabels: {
enabled: true,
rotation: -90,
color: '#FFFFFF',
align: 'right',
format: '{point.y:.1f}', // one decimal
y: 10, // 10 pixels down from the top
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
}]
});
});
},
error: function (r) {
alert(r.responseText);
},
failure: function (r) {
alert(r.responseText);
}
});
});

If i understand correctly, you would like to draw a chart for each different panelCodeUI ?
If that's the case, change your code after AJAX success with that :
var productions = seriedata.d;
var listPanelCodeUI = productions.map(function(p){return p.PanelCodeUI}).filter(function(item, pos, self) {
return self.indexOf(item) == pos;
});
//listPanelCodeUI : [21,11,31]
listPanelCodeUI.sort();
listPanelCodeUI.forEach(function(e){
datamacro = [];
//Create a div for each panelCodeUI
$("body").append("<div id='barchart" + e + "'></div>");
var divId = "#barchart"+e;
//Filter productions for specific panelCodeUI
var data = productions.filter(function(p){return p.panelCodeUI === e});
data.forEach(function(d){
var yval = d.Value;
var xval = d.Date;
var x = [xval, yval];
datamacro.push(x);
});
$(function () {
$(divId).highcharts({
...
})
})
}

That's what you need to parse your data:
charts = [];
$.each(productions.map(function(el) {
return el.PanelCodeUI;
}).filter(function(el, index, arr) {
return arr.indexOf(el) === index;
}), function(index,PanelCodeUI) {
var serie = productions.filter(function(el) {
return el.PanelCodeUI === PanelCodeUI;
});
$.each(serie, function(index, production) {
datamacro.push([production.Value, production.Date]);
});
drawChart('#barchart' + PanelCodeUI, 'LAST FIVE DAYS', datamacro);
});
Also i made this helper function to create the charts:
function drawChart(containerID, chartTitle, data) {
charts.push(new Highchart.Chart({
chart: {
type: 'column',
renderTo: containerID
},
title: {
text: chartTitle
},
subtitle: {
text: ''
},
xAxis: {
type: "datetime",
tickInterval: 24 * 3600 * 1000,
labels: {
rotation: -45,
align: 'right'
},
dateTimeLabelFormats: { // don't display the dummy year
day: '%e. %b',
},
//crosshair: true
},
credits: {
enabled: false
},
yAxis: {
labels: {
enabled: false
},
title: {
text: null
}
},
tooltip: {
formatter: function() {
return Highcharts.dateFormat('%d/%m/%Y', new Date(this.x)) + '<br/>' + ' in barrels: ' + this.y;
}
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
},
series: {
pointRange: 24 * 3600 * 1000, // one day
pointInterval: 3600 * 1000
}
},
series: [{
//name: '',
showInLegend: false,
data: data,
dataLabels: {
enabled: true,
rotation: -90,
color: '#FFFFFF',
align: 'right',
format: '{point.y:.1f}', // one decimal
y: 10, // 10 pixels down from the top
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
}]
}));
}

Optimize JavaScript DrillDown code

I have a drilldown map on my page which I would like to optimise.
Right now I am loading every "drilldown" map even if it is not clicked.
Here is an example that shows how the data is load if the state is clicked.I would like to achieve that.
But this is my code and as you can see, I am loading all drilldown jsons even if the map is not clicked. In my example I have only 2 drilldown option, but in my real life problem I have it like 15 so it really slows down a little bit everything.
So this is my code:
// get main map
$.getJSON('json/generate_json_main_map.php', function(data) {
// get region 1 map
$.getJSON('json/generate_json_region_1.php', function(first_region) {
// get region 2 map
$.getJSON('json/generate_json_region_2.php', function(second_region) {
// Initiate the chart
$('#interactive').highcharts('Map', {
title: {
text: ''
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
series: [{
data: data,
"type": 'map',
name: st_ponudb,
animation: {
duration: 1000
},
states: {
//highlight barva
hover: {
color: '#dd4814'
}
}
}],
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: [{
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
data: first_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}, {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
data: second_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}]
}
});
});
});
});
JSON from generate_json_main_map.php:
[{"drilldown":"a","name":"region 1","value":"1","path":""},{"drilldown":"b","name":"region 2","value":"2","path":""}]
JSON from generate_json_region_1.php:
[{"name":"Place 1","key":"place.php?id=1","value":"1","path":""},{"name":"Place 2","key":"place.php?id=2","value":"2","path":""}]
This is my attempt to make ajax calls load in parallel, but the map is not loading, I get just the coloraxis.
$(function() {
$.when($.getJSON('json/generate_json_main_map.php'), $.getJSON('json/generate_json_region_1.php'), $.getJSON('json/generate_json_region_2.php')).done(function(data,first_region,second_region){
$('#interactive').highcharts('Map', {
title: {
text: ''
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
series: [{
data: data,
"type": 'map',
name: st_ponudb,
animation: {
duration: 1000
},
states: {
hover: {
color: '#dd4814'
}
}
}],
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: [{
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
data: first_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}, {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
data: second_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}]
}
});
});
});
I can see that the jsons are loaded and there is no JS error shown by firebug.

If you want to load on click, you need to call the state data on click_event (and not at startup).
Just like your JSFiddle example:
chart : {
events: {
drilldown: function (e) {
// Load you data
// show it with chart.addSeriesAsDrilldown(e.point, {...});
}
}
}
Or as #Whymarrh suggests, you can load them all in parallel (instead of one after the other) and once they are all retrieved, compute your map.
See https://lostechies.com/joshuaflanagan/2011/10/20/coordinating-multiple-ajax-requests-with-jquery-when/ for example on how to execute a code after all ajax calls have completed.

When you load your map data as you did, in the following manner:
$.when(
$.getJSON('json/generate_json_main_map.php'),
$.getJSON('json/generate_json_region_1.php'),
$.getJSON('json/generate_json_region_2.php')
).done(...);
The effect is this - when any of the three requests fail, all promises will be rejected and ultimately, your map never gets to be initialised.
A better approach could be to request all data independently, and the outcomes would be handled as follows:
If the request for the main data fails, abort the other requests unconditionally (there would be no need for a drill down if the primary data is non-existent).
If request for main data succeeds, you may go on and initialise the map as data becomes available. The request for drill down data may or may not succeed though (but half bread is better than none?). Assuming everything goes well, then in the event that user initiates a drill down action, you show a loading message and ultimately add the drill down series when it becomes available.
Here's an implementation of the method I offered:
$(function () {
// immediately trigger requests for data
var loadMainData = $.getJSON("json/generate_json_main_map.php");
var loadRegionData = {
"region-1-name": $.getJSON("json/generate_json_region_1.php"),
"region-2-name": $.getJSON("json/generate_json_region_2.php")
};
// region drilldown options
var regionalSeriesOptions = {
"region-1-name": {
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
point: {
events: {
click: function () {
var key = this.key;
location.href = key;
}
}
}
},
"region-2-name": {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
point: {
events: {
click: function () {
var key = this.key;
location.href = key;
}
}
}
},
// ...
"region-(n-1)-name": {
// series options for region 'n-1'
},
"region-n-name": {
// series options for region 'n'
},
"region-(n+1)-name": {
// series options for region 'n+1'
}
};
// main options
var options = {
title: {
text: ""
},
series: [{
type: "map",
name: st_ponudb,
animation: {
duration: 1000
},
states: {
hover: {
color: "#dd4814"
}
}
}],
events: {
drilldown: function (e) {
var regionName, request, series, chart;
if (e.seriesOptions) {
// drilldown data is already loaded for the currently
// selected region, so simply return
return;
}
regionName = e.point.name;
request = loadRegionData[regionName];
series = regionalSeriesOptions[regionName];
chart = this;
chart.showLoading("Loading data, please wait...");
request.done(function (data) {
// series data has been loaded successfully
series.data = data;
chart.addSeriesAsDrilldown(e.point, series);
});
request.fail(function () {
if (loadMainData.readyState !== 4) {
// do you really want to cancel main request
// due to lack of drilldown data?
// Maybe half bread is better than none??
loadMainData.abort();
}
});
// whether success or fail, hide the loading UX notification
request.always(chart.hideLoading);
}
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: []
}
};
loadMainData.done(function (data) {
options.series[0].data = data;
$("#interactive").highcharts("Map", options);
}).fail(function () {
Object.keys(loadRegionData).forEach(function (name) {
// if primary data can't be fetched,
// then there's no need for auxilliary data
loadRegionData[name].abort();
});
});
});
Since I don't know every detail of your code, it's left for you to find a way to fit it into your solution.

Highstocks: How to define the span colors of a line instead of the individual line color

I am creating a Gantt Chart using Highstocks(compare multiple series).
1. I want to have the First span color to be Red, the second Blue and third Green.
How can I do the same?
2. how can i set the tooltip to show the values of all the points on the line instead of all points at the time.
3. How to fix y-axis and it should add scroll as values increase.
Please check the Gantt Chart Fiddle here.
var partNumber="2724070125R Planned,2724070125RActual,5511822432R Planned,5511822432RActual";
var partNum = partNumber.split(",");
var ganttData = [
[[Date.UTC(2013,11-1,07),1], [Date.UTC(2013,11-1,29),1], [Date.UTC(2013,11-1,30),1]],
[[Date.UTC(2013,11-1,20),1.25],Date.UTC(2013,11-1,21),1.25],Date.UTC(2013,12-1,21),1.25]],
[[Date.UTC(2013,11-1,13),2],[Date.UTC(2013,12-1,10),2],[Date.UTC(2014,02-1,14),2]],
[[Date.UTC(2013,11-1,21),2.25],[Date.UTC(2013,11-1,21),2.25],[Date.UTC(2013,11-1,30),2.25]]];
$( document ).ready(function(){
$(function() {
var seriesOptions = [],
yAxisOptions = [],
seriesCounter = 0,
names = partNum,
colors = Highcharts.getOptions().colors;
var data=ganttData;
$(function () {
$.each(names, function(i, name) {
seriesOptions[i] = {
// name: data[i][1],
name:name,
step:true,
data: data[i]
};
// As we're loading the data asynchronously, we don't know what order it will arrive. So
// we keep a counter and create the chart when all the data is loaded.
seriesCounter++;
if (seriesCounter == names.length) {
createChart();
}
});
});
// create the chart when all data is loaded
function createChart() {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#ganttChart').highcharts('StockChart', {
chart: {
},
title: {
text: 'PPAP Cumulative Status'
},
rangeSelector: {
selected: 4
},
xAxis: {
type: 'datetime', ordinal: false //this sets the fixed time formats
},
yAxis: {
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}],
min:0 },
plotOptions: {
series: {
lineWidth: 3,
states: {
hover: {
enabled: true,
lineWidth: 3
}
}
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b><br/>',
valueDecimals: 0
},
series: seriesOptions,
exporting: {
enabled: false
}
});
}
});
});

1) You can set for series only one color. Here:
$.each(names, function(i, name) {
seriesOptions[i] = {
name: name,
step: true,
data: data[i],
color: 'yourColor'
};
...
});
2) In tooltip, you have access to series via this.points[0].series.data etc. So you can get all points.
3) Scroll is not supported.

Not able to find the id in javascript

I'm trying to plot a graph inside a div which is dynamically created. A string of HTML divs is passed from the backend and then it is appended to the comparison_widgets div. Then a call to a function is made which needs to plot a graph(Highcharts) inside that div.
But when it goes to the function it says
Error: Syntax error, unrecognized expression: #id_Asia/Pacific_NorthAmerica
throw new Error( "Syntax error, unrecognized expression: " + msg );
It is not able to find the id, i guess. Where I'm going wrong?
Here result[1] is the div string, ie
