How to set error bar thickness in ERRORPLOT()? [message #88579]

Dear Folks,

Is there a way to change the line thickness used to render the error bars in errorplot()?

I'm running IDL 8.3 under MacOS. The documentation for errorplot does not seem to
address this question. I've tried setting thick=2, sym_thick=2, xthick=2, and ythick=2.
Each changes the thickness of the relevant plot element (plot line, plot symbol
weight, x-axis thickness, y-axis thickness, respectively), but none changes the
thickness of the error bars.

Any pointers would be much appreciated.

All the best,

David

If all else fails, you can try the ERR_THICK keyword to cgPlot.

Hi David,

Ack. Currently, there is no way to easily change the thickness or the linestyle. I'm adding in these properties as we speak...

In the meantime, if you're desperate, you could open up "idlitvisplot__define.pro". Search for the _VerifyErrorBars method. Inside there, you could hack in "THICK=2, SYM_THICK=2" to the obj_new call.

Cheers,
Chris
