Chart seems to be rendering with 3 dataseries but datapoints passed to the chart seems to be empty. Also, we observed that you are using older version of CanvasJS. Kindly download the latest version of CanvasJS Charts from our download page.
If the issue still persists, kindly create a JSFiddle with sample data reproducing the issue you are facing and share it with us so that we can look into the code, understand the scenario better and help you resolve it.
