Hi Sergey:

Glad our documentation was able to help you figure out the problem.

It appears what you want is black lines (and text) on a white
background.  These are discrete colours (as opposed to continuous) so
it is simply a matter of setting up the PLplot discrete colour mapping
(cmap0) correctly.  Likely the simplest way of doing that is what was
used for page 1 of example 16, namely a call to

plspal0( "cmap0_black_on_white.pal" );

"cmap0_black_on_white.pal" is one of our useful internal cmap0 colour style
files, but you can also make and use your own such file.
