  • in reply to: Define the pitch/step of the chart #15693

    Hello,

    Interval isn’t what I need.
    Here a representation about step/pitch/interval between points:

    Is it possible to change this value ? At this moment this value is defined automatically based on the number of data: more you have points, less this value is important.
    In my example we can consider the step is 50px (for example), if I add data, this step will change and will be less than 50px. I would like to control this step in order to say to the chart “whatever the number of data the step will be the same”. Is it possible ?
    I know maximum exists (https://canvasjs.com/docs/charts/chart-options/axisx/maximum/) it will fix the step by locking the axis, but it’s not exactly what I’m looking for !

    Second question:
    When you define the width of the chart like that:
    <div id="chartContainer" style="height: 400px; width: 800px;"></div>
    800px will be the width of everything and not only the points.
    Representation:

    Thank you for your help !

    Second question:
    The width of the chart is the width of all the chart, is there a way to control the width of the chart with data (from the first point to the last point) only (without titles…) ?

    in reply to: Get coordinates of a point #15613

    Hello,

    I have another question about coordinates:
    Is it possible to get coordinates of axis X and Y ?

    If I understood convertValueToPixel right, I have for example this data: [[0,12],[10,66],[20,42]]
    And in order to get coordinates of [10,66], I need to write:
    chart.axisX[0].convertValueToPixel(10) and chart.axisY[0].convertValueToPixel(66) ? Is that correct ?

    Then if that’s right I just have to write chart.axisX[0].convertValueToPixel(0) and chart.axisY[0].convertValueToPixel(0) to get the coordinate of axis X?

    Thank you.

    Regards.

    Hello Suyash Singh,

    Thank you for your answer.

    I saw we can get the number of event but what I want is the value/label of X when I zoom or when I use the pan. I don’t really understand how it works, can you tell more ?

    Best regards,
    Emeric

    I have another question with viewport.
    For example I have this graph: https://canvasjs.com/docs/charts/basics-of-creating-html5-chart/zooming-panning/
    We can zoom by using drag & drop, is it possible to get the viewportMinimum and the viewportMaximum of this zoom ?
    I tried to console.log both but it’s “undefined”. Is it possible to get this value after zooming with the mouse ?

    Thank’s !

    Amazing, thank you a lot !

    Example for the grid: When I click on a button, the grid appears/disappears

    Thank you !

    And is it possible to create a stripLine dynamically ?
    For example I have a graph and when I click on a button, it will add a new StripLine.

    Same question for grid, is it possible ?
