I'm newbie with D3 and NVD3 charts.
I'm trying to create a line chart, and at the end of each line, I want to display the final values.
Something like this:

or fix the tooltip legend to show at the end, like this:
This is my example:

I am using Datatables to create Highcharts. Everything functions as intended, however I am not sure how to extract the X axis title from Column 1. (Data1, Data2, Data3, Data4, Data5 etc.). I am not sure what am I missing in my code. Any advice would be appreciated because I don't know much about Javascript. Thanks in advance.
The chart should look like this.
See screenshot below.
Link to code - http://live.datatables.net/muvoyacu/2/edit
$(document).ready(function() {
var table = $("#example_full2").DataTable({
searching:false,
lengthChange: false,
ordering: false,
info: false,
paging: false,
} );
//var salary = getSalaries(table);
var salary = getRow(table,0);
var salary2 = getRow(table, 1);
var salary3 = getRow(table, 2);
var salary4 = getRow(table, 3);
var salary5 = getRow(table, 4);
// Declare axis for the column graph
var axis = {
id: "salary",
min: 0,
title: {
text: "Number"
}
};
// Declare inital series with the values from the getSalaries function
var series = {
name: "2012",
data: Object.values(salary)
};
var series2 = {
name: "2013",
data: Object.values(salary2)
};
var series3 = {
name: "2014",
data: Object.values(salary3)
};
var series4 = {
name: "2015",
data: Object.values(salary4)
};
var series5 = {
name: "2016",
data: Object.values(salary5)
};
var myChart = Highcharts.chart("container", {
chart: {
type: "column"
},
title: {
text: "Test Data"
},
xAxis: {
categories: Object.keys(salary)
},
yAxis: axis,
series: [series, series2, series3, series4, series5]
});
// On draw, get updated salaries and refresh axis and series
table.on("draw", function() {
salary = getSalaries(table);
myChart.axes[0].categories = Object.keys(salary);
myChart.series[0].setData(Object.values(salary));
});
});
function getSalaries(table) {
var salaryCounts = {};
var salary = {};
}
function getRow(table, row) {
var chart = {};
var data = table.row(row).data();
for (i=1; i<data.length; i++) {
var x = $( table.column( i ).header() ).html();
var y = data[i].replace(/[^0-9.]/g, "") * 1;
chart[x] = y;
}
return chart;

I have a map of this form
Object{485:Array[4],2072:Array[4],9665:Array[3]...}
I would like to display a chart per key.
I have an example which is similar to what i'm looking for and i tried to display my values in many charts : In this example, my key is : car_id
First step : sort my array to get a map with my keys. It works fine. But the second one is not working... I would like to display a chart per data based on car_id and per panel bootstrap...
What am I doing wrong ?
Thank you

There are a couple of problems with your code.
First, you are only using a single canvas element. Each chart needs its own canvas element. Because of this every chart you add simply renders on top of the prior chart.
At a minimum, you have to give each item a new canvas. You could change your code to accomplish that.
Change the root element for the charts to a basic <div> element that you will append the charts to.
<div class="panel-body">
<div id="chart-holder"></div>
</div>
I would create a variable to hold the cart count, and the root element.
var chart_holder = $('#chart-holder');
var chart_count = 0;
Change the for loop to use these new variables.
for (var i = 0; i <= car_type.length - 1; i++) {
chart_holder.append('<canvas id="myChart' + chart_count + '" width="400" height="400"></canvas>')
var ctx = $("#myChart" + chart_count);
var data = [];
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: [car_type[i].full_option],
datasets: [{
label: '# of Votes',
data: [car_type[i].price]
}]
},
options: chart_opts
});
chart_count++;
}
This will create a new chart for each object in each array.
I created a fiddle to demonstrate.
Based on the data, however, I would recommend a different approach. I would create a single chart per unique key, rather than a chart for every element.
You would need to parse each array to pull out labels and data for each chart. Here is an example that would get that data out of each array. There is a variable to capture the data for the chart and the labels for the chart.
var car_data = [], car_labels = [];
for (var i = 0; i <= car_type.length - 1; i++) {
car_data.push(car_type[i].price);
car_labels.push(car_type[i].full_option);
}
We can pass car_data and car_labels to the Chart.js initialization.
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: car_labels,
datasets: [{
label: 'Car Type ' + ct,
data: car_data
}]
},
options: chart_opts
});
Here is a fiddle to demonstrate a single chart per car_id.
I am trying to create a simple real time chart using epoch.js which updates itself on a click event.
My code posted below has a total of 3 functions. They are:
1) generate a random value
2) generate the current date and time in milliseconds.
3) onclick event that updates chart datapoints.
Though I have datapoints in the right format as required for the chart. I am unable to update it .
Appreciate any help on find out as to why the graph is not working as it should.
///////////////this function generates the date and time in milliseconds//////////
function getTimeValue() {
var dateBuffer = new Date();
var Time = dateBuffer.getTime();
return Time;
}
////////////// this function generates a random value ////////////////////////////
function getRandomValue() {
var randomValue = Math.random() * 100;
return randomValue;
}
////////////// this function is used to update the chart values ///////////////

You are pushing the wrong object to barChartInstance when updating the graph. You need to just push the array containing the new data point, instead of pushing the full configuration again.
function updateGraph() {
var newBarChartData = [{time: getTimeValue(), y:getRandomValue()}];
/* Wrong: don't use the full configuration for an update.
var newBarChartData = [{
label: "Series 1",
values: [{
time: getTimeValue(),
y: getRandomValue()
}]
}, ];
*/
barChartInstance.push(newBarChartData);

var Time = dateBuffer.getTime();

Ok I have a graph using Highcharts.JS that is populated by an api call providing it with XML data.
I have managed to get the data to push and display on the graph as such, but now I am having the issue of "What happens when there is no data for "x" component" In which I found out that it makes the whole graph blank until you click to hide "x" component on the legend.
So I was thinking that I could probably do some conditional to have it check if there is actually data in the array that is made from the XML.

I've attempted to us isnan() as I was told it would be doable with it, but that didn't have any results.
There is already a way to handle this in highcharts. See noData.
noData: {
style: {
fontWeight: 'bold',
fontSize: '15px',
color: '#303030'
}
}
You need to include an extra library (modules/no-data-to-display.js) from highcharts but it is dead simple.
I've been looking through tons of examples but I can't seem to get my code to pull out the data. The chart is blank.
I have a php file that gives the following: (date, value1, value2)
[
["2013-09-15 08:44:37",19.8,8.19],
["2013-09-15 08:47:37",18.4,7.81],
["2013-09-15 08:50:37",18.3,7.78],
["2013-09-15 08:53:37",18.1,7.77]
]
I then have the following code:
<!DOCTYPE html>
<head>
<script src="js/jquery-1.10.2.min.js"></script>
<script src="js/highcharts.js" type="text/javascript"></script>
<script>
var chart;
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'line',
},
title: {
},
xAxis: {
type: 'datetime'
},
yAxis: {
},
series: [{
name: 'val1',
data: []
}, {
name: 'val2',
data: []
}]
};
$.getJSON('data_day.php', function(json) {
val1 = [];
val2 = [];
$.each(json, function(key,value) {
val1.push([value.time, value.val1]);
val2.push([value.time, value.val2]);
});
options.series[0].data = val1;
options.series[1].data = val2;
chart = new Highcharts.Chart(options);
});
});
</script>
</head>
<html>
I'm trying to use firebug to see where I've gone wrong. If I put
console.log(key,value)
under the $.each I can see the data:
0 ["2013-09-15 08:50:37", 18.3, 7.78]
1 ["2013-09-15 08:53:37", 18.1, 7.77]
2 ["2013-09-15 08:56:37", 18.2, 7.8]
Is there a problem with the
val1.push([value.time, value.val1]);
or
options.series[0].data = val1;
Update: Changed it to this and its now working.
val1.push([value[0], value[1]]);
val2.push([value[0], value[2]]);
As per Pal's comment - changed it to this:
val1.push([value[0], value[1]]);
val2.push([value[0], value[2]]);
