pixel out of range when plotting

["J. Bardon" <bardon@crmc2.univ-mrs.fr>]

Hello,

I'm using midas98NOV under RedHat.

When I plot any file, the plot order works fine but I always obtain the
two lines
y-pixel outside valid range
y-pixel outside valid range

Stat/image used on the plotted files does not show any anomaly; the same
files were plotted without problem when using midas95NOV.
That's not a severe problem but is boring when plotting series of
curves.

If someone could help...

Thanks
PS
With ECHO/ON
the plot order gives the lines:
