I was wondering if there are any plans to introduce a “symmetric log scale” (symlog) in the future, as one of the axis display options for plots?
I’ve seen the topic appear in some previous talks (2015, 2017) but as far as I can tell, this feature is not yet implemented. I’ve found that there are quite a few circumstances where it can be handy to have such an axis for a plot, e.g. one is looking at the distribution of some variable that covers many orders of magnitude and which can be either positive or negative.
My present workaround (which I’ve seen others use) is to display such histograms with the Python matplotlib package, which implements this feature, but it would be great to be able to use ROOT’s own plotting abilities.
