Axis X combines label with x value bug

    Not sure if is a bug or some property i did not know how to enable. But when i create a linear chart and i use for
    dataPoints : {
    x : number;
    y : number;
    label : string;
    I expect that on axisX only labels should exist, but no. It makes a combination of some labels and some x value numbers thrown in there like this example : https://jsfiddle.net/5Ld648eg/1/

    var y = 0;
    var data = [];
    var dataSeries = { type: "line" };
    var dataPoints = [];
        y: 3000,
        label: '2014-05-06 12:02 PM'
       // x: '2014-05-06 12:02 PM'
    		x: 10,
        y: 3100,
        label: '2014-06-06 12:02 PM'
        //x: '2014-06-06 12:02 PM'
    		x: 14,
        y: 3500,
        label: '2014-07-06 12:02 PM'
        //x: '2014-07-06 12:02 PM'
    		x: 26,
        y: 4000,
        label: '2014-08-06 12:02 PM'
        //x: '2014-08-06 12:02 PM'
    dataSeries.dataPoints = dataPoints;
    //Better to construct options first and then pass it as a parameter
    var options = {
        zoomEnabled: true,
        title: {
            text: "Try Zooming - Panning"
        axisX: {
            labelAngle: -60,
        axisY: {
            includeZero: false
        data: data  // random data
    var chart = new CanvasJS.Chart("chartContainer", options);


    You seem to be passing both x-value and label because of which it shows few numbers in between based on the axis interval. Passing just y-value and label should work fine in your case.

    Please take a look at this JSFiddle for a working example.

    Thank you for the answer, yeah it works only with label and y value. But I want to create a different type of graph.
    Usually the multi-series line chart looks like this : https://canvasjs.com/docs/charts/basics-of-creating-html5-chart/multi-series-charts/
    (where all the lines have points in front of the same label).

    But i want somethink like this : desired graph

    example of what i want

    Like where the points should not be coordinated to the lines, but rather points in lines can alternate. That’s why I can push the points how i want by adding the X value(I really want labels on X axis to be strings, not numbers). If i don;t add x, the canvas js will force the points placement to be perpendicular and in match with the other points.

    So do you have any other suggestions? or maybe i should use a new type of graph… Because right now seems like more of a bug, because it can’t interpret x value and label. I think a good behaviour(but is just my opinion), when a user adds x,y and label, x & y -should be for drawing purpose, and label strictly for displaying under the ox line.



    You can set x-value along with y-value and labels sequentially starting from 0. In case a particular dataseries does not have datapoints for each x-value, you can skip them.

    Please take a look at this JSFiddle for a working example.
