Re: [Plplot-general] deleting only plotted data lines

[Vince D. <vi...@sa...>]

I did some real-time stuff with Plplot's tkwin widget several years back,
and found it pretty fast.  I tried various approaches, including drawing
the previous data in the background colour to delete it.  I even hacked a
scrolling feature to create a kind of moving time-series.

All of the above worked reasonably well, although the simple approach of
replotting the entire graph was also quite reasonable in speed.
