Didn't think of error handling since I still don't think it's an
error. Good old "I don't see, therefore it's not there"-approach...

Moempf, and even if I use CATCH I still need to include a certain
block of code in every plot routine I have - and all that to catch an
error that isn't one. So what if I want to plot only NaNs? How's that
different from wanting to divide by zero or by NaNs? Which, I might
add here, will not produce an error.

Not happy
