CgBarPlot with NaNs? [message #85756]

I'm using David's CgBarPlot routine and I have 4 data arrays I'd like to plot but one of them contains NaNs at the end which produces "infinite" bar heights.

If I truncate the NaNs from the array then the horizontal spacing then doesn't stay consistent with the other 4.

Is there a way around this?

Cheers

I check for NaNs in cgBarPlot, but I wasn't following up with the data
display. Now the length of a bar with a NaN is set to 0. You can find an
updated version here:

I checked in changes to a number of Coyote Library programs today. It
may be time for a library update:
