X axis scale and "colz" option for bidim spectra


The color scale of a bidim spectrum drawn with “colz” option covers the x axis scale when a factor as 10^x is required (cf. red circle on the attached figure). So I’m looking for a solution to move down the x axis scale factor (automatically if possible). Maybe it 's just a simple command to add to my rootlogon (where I already modified my canvas), but I have no idea how to do that.

Thank you for help,


here is an example showing how to move the palette
