Plotting in sage 4.8 defaults to firefox, WHY?
I have just installed sage 4.8. On my system I have gnuplot, gnuplotpy, surf,matplotlib, and perhaps some others. I want plot() in sage to default to ANY of these instead of bringing up firefox to plot a png.
I can get gnuplot if I use a maxima command. Is there any way to get sage to default to some other plot?
Does [this](http://ask.sagemath.org/question/947/how-to-change-the-default-program-which-open-the) answer your question?
