• bug fixing
• new feature

What does this PR do?

This PR shrinks the grid size such that the axis labels and names are completely contained (Option (B) of #9265 (comment)).

Fixed issues

• xAxis.nameGap and yAxis.nameGap should be set automatically given grid.containLabel #9265: xAxis.nameGap and yAxis.nameGap should be set automatically given grid.containLabel

Details

Before: What was the problem?

When grid.containLabel is set to true, the axis names overlap with the labels, when there is no magical number for nameGap specified. Furthermore, the names may be not visible when specifying the nameGap, because the names get pushed out of the grid. Therefore, also the distance between the grid and the container needs to be adjusted.

After: How does it behave after the fixing?

When grid.containLabel is set to true, the axis names do not overlap with labels and the grid size is shrinked such that the names are completely visible without the need to specify the grid to container distance or nameGap.
