An axis that can extend its range, keeping the number of its bins unchanged.
The axis is constructed with an initial range. Apart from its ability to grow, this axis behaves like a RAxisEquidistant.

This axis kind can increase its range.
Reimplemented from ROOT::Experimental::RAxisEquidistant.
Grow this axis to make the "virtual bin" toBin in-range.
This keeps the non-affected axis limit unchanged, and extends the other axis limit such that a number of consecutive bins are merged.
Example, assuming an initial RAxisGrow with 10 bins from 0. to 1.:
Grow(0)
: that (virtual) bin spans from -0.1 to 0. To include it in the axis range, the lower limit must be shifted. The minimal number of bins that can be merged is 2, thus the new axis will span from -1. to 1.Grow(-1)
: that (virtual) bin spans from -0.2 to 0.1. To include it in the axis range, the lower limit must be shifted. The minimal number of bins that can be merged is 2, thus the new axis will span from -1. to 1.Grow(50)
: that (virtual) bin spans from 4.9 to 5.0. To include it in the axis range, the higher limit must be shifted. Five bins need to be merged, making the new axis range 0. to 5.0.toBin | - the "virtual" bin number, as if the axis had an infinite number of bins with the current bin width. For instance, for an axis with ten bins in the range 0. to 1., the coordinate 2.05 has the virtual bin index 20. |
