i've done how you told me but i'm encountering two problems: 1) When i zoom on the Y axis, the minimum does not longer stay blocked, but unfortunately when i try to unzoom the following error appears:
Error in <THistPainter::PaintInit>: log scale is requested but maximum is less or equal 0 (0.000000)
2) Along the X axis the correct zooming process is allowed only if the lower limit is set to 5-6. If lower than this the minimum is always 10e-2.
Regards,
MC
