I would like to set logarithmic scale on the content of a 3D histogram (I am using “BOX2Z” draw option) without setting any of the three axes to logarithmic scale.
In case of a 2D histogram I can use gStyle->SetLogz(), but this is not possible in this case since it changes both the color palette and the z axis to logarithmic.
It is true that there is no “4th axis” to the log scale on it. You can set the log scale on X Y and Z axis but not on the TH3 Content.
Maybe we can implement extra draw option for that - like
Or something more generic that can be combined with the existing options for 3D histograms. Like "LOG3D"or “LOG3”.
But we do have only
box draw option which make sense to combine with log content scale.
We have 4 different BOX options, ISO, and SCAT (even if it is deprecated). The new option will have to display the log of the content instead of the content itself. So all the options are concerned.
Thank you all for the replies and for considering my request: it would be a nice additional feature!
