Hello Rene,
sorry, this is not what I meant... I'd like to have
a "continuous" X-axis (but broken in two part), a single
Y-axis (on the left for example)... so that it looks like
the spectrum has been zoomed in where the feature are
interesting... I hope this small ascii "drawing" will work...
LogY
/\
.
.
. My TH1F...

.-------------//-------------------//------------------>
(100->300) (2500->3500) (5500->6500) Lin X
Thanks,
Fred
