CanvasJS Chart supports all versions of angular and chart seems to be working fine in Angular 8. Please take a look at this Sample project for a working example on creating column chart in Angular 8.
If you are still facing the issue, kindly share sample project reproducing the issue over Google-Drive or Onedrive so that we can run sample locally at our end, understand the scenario better and help you out.
