I am plotting data points on maps using the map functions in idl and
using the Z-device. When the points are close to the plot boundary,
the program occasionally crashes and complains about too few valid
data points. It crashes when trying to call the 'oplot' procedure (for
each individual point). The peculiar thing is that this works
perfectly using other devices (as 'x', 'cgm'). And the even more
peculiar thing is that this depends on the value of oplot's keyword
'symsize'. For example if I use symsize=0.4 it crashes, whereas
symsize = 0.38 or 0.42 works without problems...
I must admit this belongs to the more weird things I have experienced
with idl.
When I use the 'convert_coord' function, it doesnt seem though as the
problematic points are outside the plotting area (device coordinates
are larger than 0).
Has anybody any similar experiences?
