[Plplot-devel] Small problem with color map 0

[Arjen M. <arj...@wl...>]

Hello,

I am trying to use more than 16 colours in color map 0. 
At first, the picture came out all in black instead of
coloured and then I saw a myriad of messages about 
"color map 0 hosed".

This happens in rdbuf_state(). It checks if the colour
index exceeds 15 or not. 

I have temporarily excluded this error message and
the resetting of the index to 1 (hence the black 
colour), but shouldn't the check be:

 if ( (int) icol0 >= pls->ncol0 ) {
    ...
 }

Regards,

Arjen
