PLOTERR Procedure

Note: Please see the newer ERRORPLOT function, which replicates the functionality of this older routine but offers an interactive interface and updated functionality.

The PLOTERR procedure plots individual data points with error bars.

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