Can you kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive along with the sample data so that we can run the code locally at our end, understand the scenario better and help you out?
Unless we run your code locally it’s difficult to reproduce the issue or understand your exact requirements or the solution that we provide may not work properly due to the variation in chart-options being used by you and us.
A sample project helps us in figuring out the issue and suggesting an appropriate solution accordingly.

You can convert the JavaScript Date to Shamsi date format using the lines of code as shown in this StackOverflow link. For achieving the same in charts, you can use labelFormatter of axisX and contentFormatter of toolTip as shown in this JSFiddle.
Considering this as a duplicate of shamsiDate in canvasjs and hence closing the same.
