Let PlotHelper not crash upon failing single-axis invocation
Let's say a plot happens on an axis grid and some axes are not set, e.g. due to a col_wrap
that does not fill the grid completely... in such cases, the PlotHelper
fails and the whole plot cannot be created.
Proposal
- Detect such cases and forego errors.
- Be less strict in general, not issuing errors and exceptions but warnings...
