Re: Problem while using waitforbuttonpress function

[Giox79]

Thanks a lot,
well I tried the suggested approach, the ginput(1) approach works fine, but
wasn't good for me since it was quite slow and furthermore I have to wait
for a specific keyboard character.
However  modifying the 

__gnuplot_ginput__.m

file does the right work!
I don't understand why, but it works faster, when waiting for a button press
on a fplot window.
A last question: in my original application I have to create two different
subplots, in a command like the following one:

subplot(2,1,1);
fplot ("cos", [0, 2*pi])   // In my application I show a BW image loaded
from file on hard disk
subplot(2,1,2);
fplot ("sin", [0, 2*pi])   // In my application I show a mean fft of the BW
image
a=waitforbuttonpress()


However I think this lines of code implicitly call a figure() command since
the waitforbuttonpress doesn't work.
Do you have any idea? Thanks a lot for your really useful help.

Giovanni
