Maybe we could modify the xticklabels example until we replicate the bug. It might be ordering of the commands or something.

I've isolated the issue. Labels will be shown if there are 15 or less. Any more and they silently fail

https://github.com/alandefreitas/matplotplusplus/blob/master/source/matplot/axes_objects/bars.cpp#L24 seems like a possible reason for this
