chart in widget not displaying

Hi All, I have three entities i.e,Chart,Dataset,Datapoint and i have given many to many association b/w Chart & Dataset as well as for Dataset and Datapoint i had given many to one association & many to many association. In the microflow, I have taken the chart entity as the parameter and retrieved the list of chart entity objects. I have taken the aggregate activity, to aggregate all list of objects.. Finally I have returned the Chart entity object. I used the chartjs to generate some report. I have followed the same instructions in documentation. But it is displaying nothing..It is just showing some blank on the browser. can anyone suggest me how to achieve it.

Are you using the chart in a listview or template grid. There is an issue with 6.8.0 passing context to a widget when in a listview. Tey upgrading to 6.8.1.
