Hi Jean-Eric,

 This sequence of PAW commands won't work either. You missed OPT LINY before H/PLOT. it should be:

opt linx
opt logy
Null -180 180 1e-4 1e-1

OPT LINY | <=======================

h/pl <my-2d-plot> s

You cannot do something like that in ROOT because if you do gPad->SetLiny() just before plotting the histogram the null frame will be redrawn as linear.
 I guess there is several solutions to your problem. I can think of 2: 1) create an overlay transparent pad linear in Y and drawn it above the

   log scale and plot your histo in that pad. 2) create a temporary copy of your histogram containing 10^<my-2d-histo>

   and plot it with LogY

Cheers, Olivier
