GNUPlot undo replot

[Daantje <d....@bn...>]

I have been trying to figure out how to show and not show an extra graph in a
GNUPlot graph. So far the show part is working. I plotted the graph and
replotted the extra graph with;

bind h replot 'velocities.txt' using 2:8:16  with labels center offset 0,0.4
notitle

This works fine, the extra graph only shows after pressing the h. But now I
want to be able to get rid of the extra graph preferably by pressing the
same button. I don't want to plot the original graph again since it is
pretty big. I would just like to do an undo replot. 

The extra graph I want to plot is a graph extisting of a label for each
point in the original graph. So all it really does is add labels to each
point in the graph. Since the labels block the view to the graph a bit I
only want them to display when you you either zoom in to a certain extent or
when you press some key like displayed above. But I want them to disappear
when you unzoom or press the button again.  

Does anyone have any ideas on how I could do this? Another way to get the
same result would also be welcome.

Thanx in advance,
Danielle

You rather completely misunderstand the working and intention of 'replot'.

Well, that's not going to work.  You already plot the original graph 
again when you did 'replot'.  That's what the command does: it REdoes 
the PLOT, optionally with some more datasets you specify as part of the 
replot command line.

The only way to get rid of such an addition to the display is issue a 
new 'plot' command without it.

Isn't there any way to show labels for every point in the graph and not sho=
w
them on some command or some condition without plotting the entire graph
again??? What's a smart way to solve this?

No. Note that in your previous approach (turning the labels on with a 
hot key) you were `replot`ting anyway, so it seems to me it's not a big 
deal to `replot` to turn them off.

If your plot is "big" -- by which I assume you mean there is lots of 
data -- pre-process the data to slim down the data set. Most often, if 
the (re)plotting is slow, it's because there's more data than is 
necessary for the resolution of the screen.
