Rendering flowchart is wrong

### Documentation Is:

- [ ] Missing or needed?
- [X] Confusing
- [ ] Not sure?

### Please Explain in Detail...

The flow chart is missing `afterDatasetsDraw` and `afterDraw` is not at the correct location.

### Your Proposal for Changes

Replace `afterDraw` with `afterDatasetsDraw` and put `afterDraw` after `afterToolipDraw`.

This is how it seems to work for me, didn't look at the code.
