axisY2: Object

axisY2 is the secondary axis which renders on the opposite of primary axis (axisY). It is mostly vertical, except when we are working with Bar Charts, where axisY2 is horizontal.


Notes
  • It is not applicable for Pie and Doughnut charts.
  • axisY2 contains the same properties as axisY. 

var  chart =  new  CanvasJS.Chart("container",
{
 .
 .
 axisY2: {
    
   title: "Axis Y2 Title"
 }
 .
});
chart.render();

axisY2 can also contain multiple Axis objects in the form of an array in case you need Multiple Secondary Y Axis as shown below.

var  chart =  new  CanvasJS.Chart("container",
{
 .
 .
 axisY2: [
  {
	title :"1st Secondary Axis Y Title",
   },
   {
	Title: "2nd Secondary Axis Y Title"
   }
 ],
 .
 . 
});
chart.render();

  1. Hello. I am a web developer. I have questions.
    Do you support three or more Y-axes in CanvasJS?
    If you do not support Do you have a development plan?

    • [Update]
      We have just released v1.9.5 Beta which supports Secondary X Axis and Multiple X / Y Axis. Please refer to the release blog for more information.

      Ronnie,

      Sorry, we don’t support more than 2 y-axis yet. But we’ll be working on in 2 months.

      • Thanks for the quick answer. I have had to add quite a bit of code to make my chart look decent since all the data is dynamic. Are there plans to make some kind of auto align grid lines option in the future?
