[Plplot-general] deleting only plotted data lines

[Jay C. <jea...@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
