[neutron-mc] mcdisplay zooming

[Dalgliesh, RM (Robert)]

I have compiled mcstas on a redhat 8 linux system with perl 5.8. The bulk of
the packages appear to be working fine but the zooming function in v1.7
mcdisplay for both the --multi PGPLOT and Scilab packages does not appear to
work properly.
I have tested the .out file I am using as a test with the mcstas-v1.6-ill
mcdisplay and this seems to work with no problems.
The latest version appears to add in an offset to the x-axis and also fails
to scale the 3 plots correctly.  As far as I can see the do_zoom function
appears to be the same for the PGPLOT section of the code as it was for
v1.6. Does anyone have any thoughts as to why this may now be happening?

Thanks
