Hi Karlo,

This bug has now been fixed, and will be in the next IDL release. Thanks for reporting it!

In case you're interested, we added code to compute the maximum value of the plot, so that we could adjust the plot margins in case the Y range was huge. We just needed to use /NAN when computing the maximum, so that NaN values would be skipped.

Cheers,
Chris
