Hi Kyle:

What particular devices show this issue of red lines for cmap0 index 1
despite a call to plscol0 to set a non-red colour for cmap0 index
1?

I haven't looked deeply at this, but, of course, it is possible some
device drivers might only allow cmap0 palette changes to apply to the
_next_ page or even ignore any attempts to change the pallette after
the device has been initialized. So I suggest calling
this->dataPlot.scol0 just before either your call to (1)
this->dataPlot.adv or (2) this->dataPlot.init to see whether
either/both of those gives you the desired result.
