OPLOTERR Procedure

OPLOTERR Procedure

The OPLOTERR procedure plots error bars over a previously drawn plot. A plot of X versus Y with error bars drawn from Y - Err to Y + Err is written to the output device over any plot already there.

This routine is written in the IDL language. Its source code can be found in the file oploterr.pro in the lib subdirectory of the IDL distribution.
