@armin,
Please take a look at this gallery page for an example on creating chart with multiple axes in PHP.
If you are still facing the issue in creating a chart with multiple axes, kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive so that we can look into the code, understand the scenario better and help you out.
