Your First Chart using JavaScript in under 5 minutes

This tutorial will help you get started with CanvasJS JavaScript Charting Library using basic JavaScript & HTML. Each section explains some Chart concept along with a live editor where you can practice by editing code. We encourage you to edit the code as described in the comments (inside editor) & familiarize yourself with the Charting API.


Try it Yourself by Editing the Code below.

Ready to create your first chart locally on your system using CanvasJS ?

The above code template can be used to create various types of charts. Follow the steps below to get started.

  1. Copy the code template above and save it locally as HTML file
  2. Run the saved HTML file.
    You will see the above chart running on your machine.
  3. Now change the type parameter to “doughnut”.
  4. Save the changes and run it again.
    Voilà! You just created a doughnut chart.
  5. Now, try changing the type to various other chart types like “splineArea”, “bar”, etc… and let CanvasJS do its magic.

So easy, right?!
Next Step: Go through the tutorial below to start building incredibly high performance charts easily using CanvasJS. It teaches you the basics of creating HTML5 Javascript Charts with the help of interactive samples.


Basic Column Chart

Consider the following tabular data to be rendered in the form of column chart.

Fruit Sales in first Quarter
(thousand dollars)
Banana 18
Orange 29
Apple 40
Mango 34
Grape 24

Below is how a minimal basic Column Chart would look like. Here are important things to remember

  1. Instantiate a new Chart object by sending the ID of div element where the chart is to be rendered. You can also pass DOM element instead of ID
  2. Pass all the Chart related “options” to the constructor as the second parameter.
  3. Call chart.render() method to render the chart

Chart “options” mainly contains 4 important elements.

  1. title object with its text property set.
  2. dataPoints – which is an array of all data items to be rendered
  3. dataSeries – parent of dataPoints that also defines type of chart and other series wide options
  4. data – array element which is a collection of one or more dataSeries objects. Here we have only one dataSeries.

Checkout the code below – experiment and make yourself familiar with the API.

Note

Though we are going to use Column Charts to learn various concepts, it is easy to change them into any kind of chart that you wish! Just change the type property of dataSeries to any chart type that you need – bar, area, line, scatter, stackedColum, etc.

Try it Yourself by Editing the Code below.

Checkout all the supported chart types


Multi Series Column Chart

Now, if you want to compare sales of various fruits in first and second quarter of the year, you need to add one more dataSeries (with second quarter values) to the data array. Below is how it can be done.

Fruit Sales in first Quarter
(thousand dollars)		 Sales in second Quarter
(thousand dollars)
Banana 58 63
Orange 69 73
Apple 80 88
Mango 74 77
Grape 64 60
Try it Yourself by Editing the Code below.

Customizing Chart

In the above chart we can do couple of customization to improve the visualization of data like

  1. Show values on y axis with $ as prefix and “K” as suffix. Same on toolTips
  2. Display Legend indicating Q1 and Q2

Adding Prefix & Suffix to values is quite simple. You can do so by adding axisY object with prefix and suffix properties set.

Legend can be displayed by setting showInLegend property in dataSeries to true

Below is how it would look like with above properties set. Intentionally the Title has not been set in Axis X and Axis Y. You can do so by setting the title property of axisY or axisX objects.

Try it Yourself by Editing the Code below.

Changing Chart Theme

CanvasJS comes with built in themes that change the look and feel of charts – like “light1”, “light2”, “dark1”, “dark2”.

You change theme by setting theme property of chart option to any of the available themes. Below is an example

Try it Yourself by Editing the Code below.

Alternate way of setting / updating data

Above examples show how you can pass data to the constructor while instantiating a chart object. But you can also set these options after creating the object – sometimes it is easier this way.

Options object that you pass to the constructor in the above method can be accessed via options property of chart. Using the same object you can set or update various properties of chart as below. 

chart.options.title.text = "Chart Title";
chart.options.data = [array];
chart.options.data[0] = {object};
chart.options.data[0].dataPoints = [array];
Try it Yourself by Editing the Code below.


Note
  • You should remember to call chart.render() after setting/updating the options – try to batch all updates before calling chart.render()
  • We’ve got the performance part covered! So you can even update the chart every 100 milliseconds (or less if you wish!!) – though such an update rate will not be required in most cases

More Customization

In case you have to do any more customization, below is a table that lists important objects and properties that allow you to do so. Do try out all these options on the above chart.

Customization Object Property
Set Chart Title Size title fontSize – 12,13,14, etc.
Set Chart Title Color title fontColor – red, blue, green, etc
Show Axis Y line axisY lineThickness – 0, 1, 2, etc.
Show value (indexLabels)
on top of Column / Bar 		dataSeries indexLabel – “{y}”, “${y}K”, “any text”
Set Axis X label angle axisX labelAngle – 30, 45, 90, etc

  1. Hi Team,

    Many congratulation on achieving this milestone. My query is, how can I load data or provide the input values for graph from a JSON object or a XML file because I will never like to create an array of data and when i speak about data I am referring to many many (dynamic) values generated on various calculation based on my metrics dashboard formulas.

    Regards,
    Rahul Khanna

    • It is not possible to change the label itself into links. But you can use click event of dataPoint to take user to the corresponding page when clicked.

      In that case you might also want to use “cursor” property of dataSeries/dataPoint to change mouse pointer type.

  5. My requirement is the same as Rahul Khanna, want to see an example that reads a JSON file and the values ​​are plotted. thanks

    • As of now CanvasJS doesn’t have a way to directly plot from the data inside a file. As such you need to read those values and assign the same to the chart.

    • CanvasJS is just a rendering library that draws charts on the client side. Hence you will have to write server side code to connect with any database and use CanvasJS on the client side and it’ll work fine.

  7. In the code I attached the problem is that column 1 and column 3 is not plotted. As if the value of these variables are not considered numeric by CANVASJS. For that reason handle it like this:

    stnetomax var = parseFloat (VPSs [6]);

    but it did not work

    I would appreciate your help.

    MY CODE

    window.onload = function() {
    ///////////////////////////////////////////////////
    CODE……………………………………….
    …………………………………………..

    var psañomax = vpss[1];
    var strecibomax = parseFloat(vpss[2]);
    var stimportemax = parseFloat(vpss[3]);
    var stimpmax = parseFloat(vpss[4]);
    var stbonmax = 12385583;
    var stnetomax = parseFloat(vpss[6]);
    //////////////////////////////////////////////

    var chart = new CanvasJS.Chart(“chartContainer”, {
    title: {
    text: “Concepto:” + psconnom + ” ” + psconnum // SHOW OK
    },

    data: [
    {

    type: “column”,
    name: “Año Mayor ” + psañomax, // SHOW OK
    showInLegend: true,
    dataPoints: [
    { label: “Columna 1 “, y: stimpmax }, // NO SHOW << Here is the problem
    { label: "Columna 2 ", y: stbonmax }, // SHOW OK
    { label: "Columna 3 ", y: stnetomax },// NO SHOW << Here is the problem
    { label: "Columna 4 ", y: 101558923 } // SHOW OK
    ]
    },

    • I discovered that I had an error.
      In my code in the object chart I have several DataSeries and only the first DataSeries variables was turning to float with parseFloat. Replace all variables with parseFloat and work.
      It works and looks good!!.

    • Chart requires x & y values to be numbers – enclosing them in quotes creates prolems while doing calculations internally. Glad you figured it out.

  10. Hi Sunil.

    Newbie perspective here for an already great tutorial. The following sentences need to be described (also) in plain English:

    “Above examples show how you can pass data to the constructor while instantiating a chart object. But you can also set these options after creating the object – sometimes it is easier this way. Options object that you pass to the constructor in the above method can be accessed via options property of chart. Using the same object you can set or update various properties of chart as below.”

    What is a constructor?… What is the benefit of the one approach vs the other?… the “easier this way” part?… Easier in what regard?

    Keep up the great work!

  22. I was unable to give a json format like [{“label”:”First”,”y”:”12″},{“label”:”Second”,”y”:”1″}] in column chart is that a bug or anywere i made mistake in formatting the JSON. But with the same format i can plot pie and doughnut charts. Help me with the issue. Thanking you.

    • Vishnu,

      y value should be a number and not a string. So your json should look like this [{“label”:”First”,”y”:12},{“label”:”Second”,”y”:1}].

    echo json_encode($data_points, JSON_NUMERIC_CHECK);

    }
    mysqli_close($con);

    ?>

    but it never shows two bars differently

    $(document).ready(function () {

    $.getJSON(“data.php”, function (result) {

    var chart = new CanvasJS.Chart(“chartContainer”, {
    title: { text: “GRAPH A” },
    data: [

    },
    {
    dataPoints: result

    chart.render();
    });

    });

    Pls advise.

  28. great, it is working. begin to understand how to have mutiple bar combo on one chart.

    i am using this to retrieve data from plain csv.

    $file=”data.csv”;
    $csv= file_get_contents($file);
    $array = array_map(“str_getcsv”, explode(“\n”, $csv));
    print json_encode($array);

    Noticed the output of JSON is correct. How do I have it imported / pass the info the

    $(document).ready(function () {

    $.getJSON(“data.php”, function (result) {

    var chart = new CanvasJS.Chart(“chartContainer”, {

    axisX: { suffix: ” mth”, },

    axisY: { title: “Sales”, },
    axisY2:{ suffix: ” %”, },

    title: { text: “Test” },

    data: [
    {
    type:”column”,
    toolTipContent: “2013 : {y}”,
    dataPoints: result[0],
    },
    {
    type:”column”,
    toolTipContent: “2014 : {y}”,
    dataPoints: result[1],
    },
    {
    axisYType: “secondary”,
    type:”line”,
    toolTipContent: “2013 calc : {y}”,
    dataPoints: result[2],

    • nracer,

      You just need to parse the JSON data and convert it to the CanvasJS supported format. Below is how you can do it:

      $(document).ready(function () {
      var dataPoints = [];
      var dataPoints1 = [];
      var dataPoints2 = [];
      $.getJSON(“jsonData.json”, function (data) {
      for (var i = 0; i <= data.length - 1; i++) { for( var j = 0; j < data[i].length-1; j++){ dataPoints.push( { x: data[i][0], y: data[i][1]}); dataPoints1.push({ x: data[i][0], y: data[i][2]}); dataPoints2.push({ x: data[i][0], y: data[i][3]}); } } chart = new CanvasJS.Chart("chartContainer",{ axisX: { interval: 1 }, data: [ { type: "column", dataPoints : dataPoints }, { type: "column", dataPoints : dataPoints1 }, { type: "column", dataPoints : dataPoints2 } ] }); chart.render(); }); });

    • Hi guys,

      I just struggled for few moments after which I was able to draw a line over a bar chart using canvasjs.

      Here is the code:

      //first I got the mean and confidence interval from a json file from php mysql

      var upper_bound=mean+confidence_interval;
      var lower_bound=mean-confidence_interval;
      var chartConTS = new CanvasJS.Chart(“chartContainer”,
      {
      title:{
      text: “Sample”
      },
      axisX:{
      labelFontColor: “rgb(0,75,141)”,
      },
      axisY: {
      title: “Seconds”
      },
      animationEnabled: true,
      exportEnabled: true,
      zoomEnabled: true,
      data: [
      {
      type: “column”,
      color: “#2a7b86”,
      dataPoints: [
      {x: 0, label: ‘test_name’, y: mean},
      ],
      },
      {
      type: “line”,
      dataPoints: [
      { x: 0, y: upper_bound },

  54. Hi

    How can I render the chart with class attribute of element?

    How to render using chartContainer class?

    • You can instantiate a new Chart object by sending the ID of div element where the chart is to be rendered. You can also pass DOM element instead of ID.
      Here is the jsFiddle to render charts based on class name.

  56. i need multi series line chart ,i want to take datapoints from two different text files, and assign one file values for one line and another for second line, is it possible with canvas js?

    • Absolutely, it is possible with CanvasJS!!
      First you take the values into two datapoints from the two files using Ajax, then you can pass the datapoints as elements in the data array for the chart. Simple.

  61. i need to get pie chart which having like 20% of dotted portion 40% lines and 40% grids is it possible with canvs js if so how to make it?

  62. hey, thanks for your script. its really very useful to me and easy customization. Thank you very much.

  64. Hi, I can’t find any information about this, sorry, I’ve looked for ages. I basically don’t want any lines on the graph, on the y axis, so I’ve set:

    axisY: {
    gridThickness: 0
    }

    but, I want it a line across 0, so you can see what is negative and positive by the number on 0. I basically want to remove all y axis lines, except the one at 0.

    Is this possible?

      • I have looked into this Vishwas, I think, I could use axisT stripLines as a final resort, but it’s tricky, we have dynamic charts, so we can range data from 0-100, to -40k to +40k, so to calculate the size of the stripLine would be really tricky.

        So we could have a graph from -10 to 100, and have the stripline as start: -0.5, end: 0.5, then it looks fine, but on a large graph with big numbers, this line isn’t even noticeable. So then the stripLine would need to be like, -100, to 100.

  66. simple solution :

    window.onload = function () {

    var cult = parseFloat(document.getElementById(”).value);

    var json = { “tot1”: cult , “tot2”: 110, “tot3”: 7, “to42”: 110, “tot5”: 7 };

    var dataPoints = [];
    for (key in json) {
    dataPoints.push({ label: key, y: json[key] });
    }

    var chart = new CanvasJS.Chart(“chartContainer”,
    {

    data: [
    {
    type: “column”,
    dataPoints: dataPoints
    }

  71. I tried above given code, it worked fine when inside .html file, but not displaying anything when I used it with my asp.net web page(VB 2005). Please help me I’m stuck…

  73. I saved on of the examples as a html file to run on my computer but it doesn’t seem to work. Could someone explain to me why? So that I can know how to run the graphs i create. The code I used is pasted below.

    window.onload = function () {
    var chart = new CanvasJS.Chart(“chartContainer”,
    {
    title:{
    text: “Division of products Sold in Quarter.”
    },
    axisY:{
    title: “percent”
    },
    animationEnabled: true,
    toolTip:{
    shared: true,
    content: “{name}: {y} – #percent%“,
    },
    data:[
    {
    type: “stackedBar100”,
    showInLegend: true,
    name: “April”,
    dataPoints: [
    {y: 600, label: “Water Filter” },
    {y: 400, label: “Modern Chair” },
    {y: 120, label: “VOIP Phone” },
    {y: 250, label: “Microwave” },
    {y: 120, label: “Water Filter” },
    {y: 374, label: “Expresso Machine” },
    {y: 350, label: “Lobby Chair” }
    ]
    },
    {
    type: “stackedBar100”,
    showInLegend: true,
    name: “May”,
    dataPoints: [
    {y: 400, label: “Water Filter” },
    {y: 500, label: “Modern Chair” },
    {y: 220, label: “VOIP Phone” },
    {y: 350, label: “Microwave” },
    {y: 220, label: “Water Filter” },
    {y: 474, label: “Expresso Machine” },
    {y: 450, label: “Lobby Chair” }
    ]
    },
    {
    type: “stackedBar100”,
    showInLegend: true,
    name: “June”,
    dataPoints: [
    {y: 300, label: “Water Filter” },
    {y: 610, label: “Modern Chair” },
    {y: 215, label: “VOIP Phone” },
    {y: 221, label: “Microwave” },
    {y: 75, label: “Water Filter” },
    {y: 310, label: “Expresso Machine” },
    {y: 340, label: “Lobby Chair” }
    ]
    }
    ]
    });
    chart.render();
    }

    thanks in advance

    • I would like to add that when I’ve saved and ran simpler graphs it has worked appropriately.

      An example that worked fine:

      window.onload = function () {
      var chart = new CanvasJS.Chart(“chartContainer”, {
      title:{
      text: “My First Chart in CanvasJS”
      },
      data: [
      {
      // Change type to “doughnut”, “line”, “splineArea”, etc.
      type: “doughnut”,
      dataPoints: [
      { label: “apple”, y: 10 },
      { label: “orange”, y: 15 },
      { label: “banana”, y: 25 },
      { label: “mango”, y: 30 },
      { label: “grape”, y: 28 }
      ]
      }
      ]
      });
      chart.render();
      }

  78. hi,I want custom the interval base on x axis value like if it is 12hr it should take interval=1 and more than that it should take 2 , data type of x axis is [new Date(2016, 04, 18, 5, 0), 18]

  79. Hi , how can i pass data dynamically from sql i have json data in var but i am unable to pass it into datapoint anyone help me.

    • Hi,

      You need to create a HTML page that does AJAX request and fetch the data. After getting the data, it will render a Chart. You can refer this thread.

  80. Is there any property available to give some space between x axis line and first column line. Because in my column chart X-Axis is merged with the first column line.

  81. HI!!!
    i want double column chart. it’s working if
    dataPoints: [
    { label: “banana”, y: 18 },
    { label: “orange”, y: 29 },
    { label: “apple”, y: 40 },
    { label: “mango”, y: 34 },
    { label: “grape”, y: 24 }
    ]
    },
    { //dataSeries – second quarter

    type: “column”,
    name: “Second Quarter”,
    dataPoints: [
    { label: “banana”, y: 23 },
    { label: “orange”, y: 33 },
    { label: “apple”, y: 48 },
    { label: “mango”, y: 37 },
    { label: “grape”, y: 20 }

    question>
    when i remove one banana ->
    dataPoints: [
    { label: “banana”, y: 18 },
    { label: “orange”, y: 29 },
    { label: “apple”, y: 40 },
    { label: “mango”, y: 34 },
    { label: “grape”, y: 24 }
    ]
    },
    { //dataSeries – second quarter

    type: “column”,
    name: “Second Quarter”,
    dataPoints: [
    { label: “orange”, y: 33 },
    { label: “apple”, y: 48 },
    { label: “mango”, y: 37 },
    { label: “grape”, y: 20 }

    • Mansour,

      In multiseries column chart the columns with same x values grouped together. So, you have to specify x values in each series to group the columns together.
