Use Series names as xAxis in Highcharts - javascript

I want to use my series names as xAxis. I have tried it like the code below. This code is creating multiple series but only one x axis value. Let's say in my code I want to create series for every fund and plot fund values in xAxis as well.
function draw(fund, zreturn) {
zreturn = [12.75, 11.77, 13.76];
fund = ['abc', 'xyz', 'pqr'];
var options = {};
options = {
chart: {
renderTo: 'graphDiv',
type: 'line',
Height: '400px'
},
credits: {
enabled: false
},
title: {
text: 'Fund Performance Graph',
x: -20
},
subtitle: {
text: '',
x: -20
},
xAxis: {
categories: fund
}
},
yAxis: {
labels: {
enabled: true,
format: function () {
return (this.value + '%')
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0,
},
series: zreturn.filter(function (zreturn, i) {
return fund[i]
}).map(function (zreturn, i) {
/* Then return as series */
return {
//type: 'line',
name: fund[i],
data: zreturn,
dataLabels: {
align: 'center',
enabled: true,
format: "{y:.2f}" + '%',
style: {
fontSize: "8px",
fontFamily: 'Arial',
},
}
}
})
}
var chart = new Highcharts.Chart(options);
};

I think that right now you have small mistakes in your code.
First of all you are using yAxis.labels.format as a function. It should be formatter if you want to use it as a function:
yAxis: {
labels: {
enabled: true,
formatter: function() {
return (this.value + '%')
}
}
},
Next, you have mistake in your data, it should be an array:
data: [
[i, zreturn]
],
I am here adding x value of your point as well as y value. If I will not add x value, points will always start from 0 and because you have added only one point to every series, all of them will be on the first category.
Here you can find an example how your chart may work with these small corrections:

How to position heatmap legend title in different position?

I have a heatmap that has a legend scale on the right side with label on top. I would like to know if it's possible to move the label "number of MMF share classes" below the legend scale in the same vertical position as the y-axis label on left?
https://jsfiddle.net/samwhite/5d6kL32o/2/
xAxis: {
// categories: this.value,
title: {
text: 'Date'
},
labels: {
autoRotation: [-10],
formatter: function () {
var dt = xcats[this.value];
var date = new Date(dt);
var month = date.getUTCMonth() + 1;
var year = date.getUTCFullYear()
return `${year}`
}
},
tickInterval: 45
},
yAxis: {
title: {
text: 'Price ($)'
},
labels: {
formatter: function () {
return `$${(this.value / 10000).toFixed(4)}`;
}
},
min: ymin*10000,
max: ymax*10000,
plotLines: [{
value: 10000,
color: 'darkred',
dashStyle: 'shortdash',
width: 0.2,
zIndex: 5
}]
},
tooltip: {
pointFormatter: function () {
return `NAV per share: <strong>${(this.y / 10000)}</strong>
<br/>Date: <strong>${xcats[this.x]}</strong>
<br/>Number of Share Classes: <strong>${this.value}</strong>`
}
},
legend: {
title: {
text: 'number of<br/>MMF share classes',
style: {
fontWeight: 'normal'
}
},
align: 'right',
y: 80,
padding: 20,
verticalAlign: 'middle',
symbolHeight: 300
},
colorAxis: [{
type: 'linear',
reversed: false,
layout: 'vertical',
stops: [
[0, '#c8daf9'],[1.0, '#537dca']
]
}],
An option could be use the code posted on this thread:
Quote:
Highcharts is not providing this option for legend title. You can
achieve your goal by translating your title in callback function:
function (chart) {
var title = chart.legend.title;
title.translate(x, y);
}
I've modified your code as follows:
Example:
legend: {
title: {
text: 'number of<br/>MMF share classes',
style: {
fontWeight: 'normal'
}
},
align: 'right',
//y: 80, // <- comment this line.
padding: 20,
verticalAlign: 'middle',
symbolHeight: 300
},
Then:
// After the "highcharts" settings, add:
, function(chart) {
var title = chart.legend.title;
title.translate(0, 370);
}
Here is the modified jsfiddle.

Access another series row's data on Highchart dataLabels

I want to access another series row data in series dataLabels. Here is my code.
categoriesarr = [1,2,3,4,5];
noofloandisbursed = [10, 20, 30, 40, 50];
pdo = [9, 18, 27, 40, 49];
var chart = new Highcharts.Chart({
chart: {
renderTo: 'disbursement'
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
categories: categoriesarr
},
tooltip: {
pointFormat: '<b>{point.y}</b>'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 0,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#fff'),
shadow: true
},
series: [{
name: 'No. Of Loan Disbursed',
type: 'column',
data: noofloandisbursed
},
{
name: 'Pre-Disbursement Orientation',
type: 'column',
data: pdo,
dataLabels: {
enabled: true,
formatter: function(e) {
//return ((this.point.y/series[0].point.y)*100) + '%';
}
}
}]
});
I want to show the result of (series 2 value / series 1 value) * 100 in the dataLabels concatenation with % only in second series. Unfortunately i can't access the series 1's y point values. When i tried series[0].yData, it returns the whole array, not the specific row matched with second row. I also tried to pass array, but it wasn't working. Need solution of this problem.
You can find the point from the first series by index:
series: [{
...
},
{
...,
dataLabels: {
enabled: true,
formatter: function(e) {
return (
(this.point.y /
this.series.chart.series[0].points[this.point.index].y) *
100) + '%';
}
}
}
]

Plot float up & down beyond y-axis in StockChart while dragging navigator

Here is my js code:
Highcharts.stockChart('utilizations', {
chart: {
zoomType: 'x'
},
title: {
text: 'KPI'
},
subtitle: {
text: 'CCE & PRB Utilization (%)'
},
rangeSelector: {
buttons: [{
type: 'day',
count: 1,
text: '1d'
}, {
type: 'day',
count: 3,
text: '3d'
}, {
type: 'day',

}, {

text: '2w'
}, {

text: 'All'
}],

},

},
max: 100,
min: 0,
tickInterval: 20,
plotLines: [{

}]
},

},
plotOptions: {
series: {

showInNavigator: true
}
},
legend: {

align: 'right',
verticalAlign: 'middle'
},
xAxis: {
type: 'datetime'
},
series: [{
name: 'CCE Util',
type: 'spline',
yAxis: 0,
data: (function(){
var data = [];
for (var i = 0; i < result.length; i++) {
var time = result[i]["time"];
var kpi = result[i]["cce"];
data.push([time, kpi]);
}
return data;
})(),
tooltip: {
valueSuffix: '%',
valueDecimals: 2,
split: true
}
},{
name: 'PRB Util',
type: 'spline',
yAxis: 0,
data: (function(){
var data = [];
for (var i = 0; i < result.length; i++) {
var time = result[i]["time"];
var kpi = result[i]["prb"];
data.push([time, kpi]);
}
return data;
})(),
tooltip: {
valueSuffix: '%',
valueDecimals: 2,
split: true
}
And my plot:
While dragging the navigator bar, sometimes the plot goes to the right position and sometimes it looks like the capture above. According to my experience, the plot position is related to the left end (let's note this as A) position of the navigator selector. When A is on the lowest part of the whole plot in navigator, the shown plot positioned well; and when A goes like the capture above, the plot shown sunk.
Please refer to a short demo with 100 data here: https://jsfiddle.net/ghqyvo0x/
How can I make my plot stable?
Your problem is caused by series.compare: property, which you set in plotOptions configuration object. If you delete this line of code, everything should work as you need. We could read in Highstock API:
Compare the values of the series against the first non-null, non- zero value in the visible range.
plotOptions: {
series: {
//compare: 'percent',
showInNavigator: true
}
}

Highmaps, how to pass data from CSV to my world map

I have a large CSV file from which I need to select data from various columns and put them on a highmaps map.
How can I select the columns to use for the map? Lets say that I have country names at column 0, country codes at column 8 and number of things at column 1. How can I pass them to the map.
This is the CSV reader I use:
$.get('downloads/dg_mare_piwik_countries.csv', function(data) {
// Split the lines
var lines = data.split('\n');
$.each(lines, function (lineNo, line) {
var items = line.split(',');
if(lineNo !== 0) {
var iso_country = items[9],
name=items[0],
no_items = parseFloat(items[1]);
//options.series[0].data.push([visits]);
options.series[0].data.push({
name: name,
code3: iso_country,
value: no_items
});
}
});
var chart = new Highcharts.Map(options);
});
And the Map, copied from the highmaps example
var options = {
chart: {
renderTo: 'chart_container'
},
title: {
text: 'Fixed tooltip with HTML'
},
legend: {
title: {
text: 'Population density per km²',
style: {
color: (Highcharts.theme && Highcharts.theme.textColor) || 'black'
}
}
},
mapNavigation: {
enabled: true,
buttonOptions: {
verticalAlign: 'bottom'
}
},
tooltip: {
backgroundColor: 'none',
borderWidth: 0,
shadow: false,
useHTML: true,
padding: 0,
pointFormat: '<span class="f32"><span class="flag {point.flag}"></span></span>' +
' {point.name}: <b>{point.value}</b>/km²',
positioner: function () {
return { x: 0, y: 250 };
}
},
colorAxis: {
min: 1,
max: 1000,
type: 'logarithmic'
},
series: [{
data: [],
mapData: Highcharts.maps['custom/world'],
joinBy: ['iso-a2', 'code'],
name: 'Population density',
states: {
hover: {
color: '#BADA55'
}
}
}]
};
Sorry for being perhaps too ignorant. I cannot short it out and any help will be deeply appreciated.
Thank you.

javascript variable not works in Highchart

}
},
series: [{name: 'Semana',data: [12 , 321] }, {name: 'Acum',data: [85, 65]}]
});
this is my Highchart code
when I am using javascript variable
like this
g311 = $("#g311").val();
g312 = $("#g312").val();
g321 = $("#g321").val();
g322 = $("#g322").val();
and pass this in series
series: [{name: 'Semana',data: [g311, g312] }, {name: 'Acum',data: [g321, g322]}]
it is not showing me graph please give me some way how to pass jquery variable in series (not static or PHP variable)
Seems to me you need to convert them to numbers first because input elems have values as strings:
g311 = +$("#g311").val();
g312 = +$("#g312").val();
g321 = +$("#g321").val();
g322 = +$("#g322").val();
and you need to declare these above the chart.
prefixing + converts a string to number.
