Current and expected behavior

I want to set background color to specific chart portion based on event in graph data.
When there is error I want to display red background, when there is warning I want to display yellow background.

But static background also not working.

I have tried beforeDatasetsDraw method from plugin to render background but its not working, I have added console in the same method but nothing in console as well, looks like method is not invoking.

I have tried beforeDatasetsDraw method inside filler as well, there also not working.
