I use 64 bits arch with wxmaxima 13-04.2-2 and gnuplot 4.6.4-5. I've recently updated maxima to 5.32.1-1 and I've noticed a bug when plotting in wxmaxima. For example

(%i1) plot2d(sin(x),[x,0,2*%pi]);
(%o1) "/home/david/maxout.gnuplot_pipes"

opens a gnuplot window with the sin function as usual, but

(%i2) plot2d(cos(x),[x,0,2*%pi]);
(%o2) "/home/david/maxout.gnuplot_pipes"

doesn't refresh the gnuplot window, it shows sin() instead of cos(). Moreover, if I close the gnuplot window and re-execute

(%i3) plot2d(cos(x),[x,0,2*%pi]);
(%o3) "/home/david/maxout.gnuplot_pipes"

it doesn't open a new gnuplop window. I have to close and restart wxmaxima.

I'm suffering this problem since I updated maxima to 5.32.1-1 in my 3 different machines. I've asked a friend with maxima 5.32.1/wxmaxima 13.04.2 in debian and he doen't suffer the bug, so is I think it's Arch specific

Additional info:
* Versions: maxima 5.32.1-1, wxmaxima 13-04.2-2 and gnuplot 4.6.4-5
* Plotting with wxplot2d works fine

Steps to reproduce:
* Open wxmaxima and execute kn a cell plot2d(sin(x),[x,0,2*%pi]);, execute plot2d(cos(x),[x,0,2*%pi]); in a different cell, close the gnuplot window and re-execute plot2d(cos(x),[x,0,2*%pi]);
This task depends upon

still persists for maxima 5.32.1-2

I can still replicate it with 5.33.0 and gnuplot 4.6.5.

Can you open a bug report upstream. We don't patch either maxima or gnuplot, so don't think this is a packaging bug we introduce. Maybe it is version specific or debian fixes it with some patch that is not upstream. Please post a link to the upstream bug report here.

Thanks Ronald. I'm not sure if the problem is from maxima or gnuplot, I've just open a ticket in both

This problem has been fixed upstream and maxima 5.34.0-1 refreshes the gnu plot window again.

Thanks for the notice -> closing.
