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

[Vince Darley <vince@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.

[Plplot-general] deleting only plotted data lines

[Jay Christnach <jean.christnach@is...>]

I'm working on a real time application. (althoug i'm afraid that perhaps 
things will be too slow in the end). I tried to figure out what would be the 
most time-effective way to begin a new plot with the same axes and legend. 
That is delete only the plotted representation of the data and not having to 
initialize the rest.

best greetings
