A RAxisGrow that has a label assigned to each bin and a bin width of 1.
While filling still works through coordinates (i.e. arrays of doubles), RAxisLabels allows to convert a string to a bin number or the bin's coordinate center. The number of labels and the number of bins reported by RAxisGrow might differ: the RAxisGrow will only grow when seeing a Fill(), while the RAxisLabels will add a new label whenever GetBinCenter() is called.
Implementation details: Filling happens often; GetBinCenter() needs to be fast. Thus the unordered_map. The painter needs the reverse: it wants the label for bin 0, bin 1 etc. The axis should only store the bin labels once; referencing them is (due to re-allocation, hashing etc) non-trivial. So instead, build a vector<string_view> for the few times the axis needs to be painted.
