USAGE

This routine is not called by the user program, but by Autograph itself, just before and just after each curve is drawn. The default version does nothing. The user may supply his own version to change the color, intensity, line style, etc. of selected curves.

Note: A user version of AGCHCU should not call any other Autograph routine.

ACCESS

To use AGCHCU, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
