#1379 maxima can't refresh plots in gnuplot_pipes format
Hi. I use 64 bits Archlinux with maxima 5.33.0, wxmaxima 13.04.2 and gnuplot 4.6.5 installed from Arch's repo. I've noticed a bug when plotting in maxima. 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 gnuplot window. I have to close and restart wxmaxima to get plot2d working again. Same happens with plot3d for 3D graphics
Plotting with [plot_format, gnuplot] works fine, for example
(%i4) plot2d(cos(x),[x,0,2*%pi],[plot_format, gnuplot]);
(%04) "/home/david/maxout.gnuplot"
opens a new window with the graphic. The wxplot2d function from wxmaxima also work fine. It seems that the problem only happens in the default gnuplot_pipes format
I've asked to Arch developers but they think the problem belogs to maxima or gnuplot. I'm suffering this problem since I use maxima 5.32.1 and gnuplot 4.6.4. Now I'm using maxima 5.33.0 and gnuplot 4.6.5, but the bug persists.
I've just open a ticket in maxima: https://sourceforge.net/p/maxima/bugs/2721/
That's the link of the bug I open in Archlinux: https://bugs.archlinux.org/task/38760
This issue has been fixed in maxima, see the link provided in the report. The tracker item there was closed on 2014-05-28 already.
