@jackybian Please address the mentioned issues of the PR #306. Usually, rebase the PR and push the changes in the same PR #306 so that all addressed issues can be reviewed.

Adjust e.g.:

Axis xAxis = (Axis)baseChart.getAxisSet().getXAxis(BaseChart.ID_PRIMARY_X_AXIS);
->
IAxis xAxis = baseChart.getAxisSet().getXAxis(BaseChart.ID_PRIMARY_X_AXIS);

The warnings need to be resolved too:
