maximum: Number

Sets the maximum value permitted on Axis. Values greater than maximum are clipped. maximum also set the upper limit while panning chart.

Default: Automatically Calculated based on the data
Example: 100, 350..
Notes
  • If maximum value is not set, it is automatically calculated.
  • While setting maximum, it should be taken care that maximum should be greater than minimum. 
var  chart =  new  CanvasJS.Chart("container",
{
 .
 .
 axisY:{
   maximum: 150,
 },
 .
 .
});
chart.render();

    Hi,
    What if the difference between my minimum and maximum value is just .01? My graph shows no significant changes. I want to automatically change the points to like .01 to see the significant change in my graph. help please.

    Hello, I am trying to display two charts side-by-side. mainChart displays the entire dataset with auto-scaled Y-axis. subChart shows a subset of the data but I would like its Y-axis to have the same scaling that was calculated for the mainChart, like this:

    var mainChart = new CanvasJS.Chart(“container”,
    {
    axisY:{
    // maximum not set (automatic scaling)
    }, },
    });
    mainChart.render();

    var subChart = new CanvasJS.Chart(“container”,
    {…
    },
    });
    subChart.options.axisY.maximum = mainChart.options.axisY.maximum,
    subChart.render();

    But mainChart.options.axisY.maximum is not defined. Is there another way to retrieve the axis range that was calculated?

      Phil,
      It is not possible to set the axis maximum from one chart to another chart directly. As a workaround you can calculate the maximum of Y-axis data and then assign the axisY maximum for both the charts using
      chart1.options.axisY.maximum = chart2.options.axisY.maximum = maxValue(chart1.options.data[0].dataPoints);

      Here is an example that will help you.
