Public bug reported:
The menu entry plot2d seems unfit to invoke actual plots.
(%i1) f(x):=x;
(%o1) f(x):=x
Put cursor on first line, go plot > plot 2d, expression is pre-set to f(x):=x,
just click ok
(%i2) plot2d([f(x):=x], [x,-5,5])$
plot2d: expression evaluates to non-numeric value everywhere in plotting
range.
plot2d: nothing to plot.
(Setting expression to 'h(x):=x' in dialog gives same problem)
What works though is specifying the function by name as first argument to
plot2d (notice it has been given as "[f(x):=x]) when invoked from the menu:
(%i3) plot2d(f(x),[x,-5,5]);
(%o3) ["/tmp/maxout11321.gnuplot_pipes"]
[graphics comes up]
Expectation would of course be that whatever the menu entry does,
results in a plot and not in an error.
