Multiple plots: oddities (bugs?), missing features in Xmaxima and wxMaxima

Thanks, Mario:
It does seem that draw2d addresses the issues mentioned before. I had focused on plot2d since it seems to have a simpler interface, but draw2d seems manageable.?

multiplot_mode seems nearly identical in functionality to the previously mentioned hold. And the first call immediately opens a blank window which is reminiscent of the "figure" function mentioned before. I suppose??terminal=[screen, 1] translates to something similar to the raw gnuplot instruction "set term x11 1" as mentioned before.

It seems as though draw2d interface may perhaps be cosmetically simplified... for example, it seems that the declaration explicit/implicit could be made?optional -- if it is not already so -- since the absence/presence of an equal sign , =, provides the same information (if I understand correctly). So that??for example[ x^3,x,-1,1] can be unambiguously inferred to mean?explicit(x^3,x,-1,1) whereas [y^2=x^3-2*x+1, x, -4,4, y, -4,4]?could be?unambiguously?inferred?to mean?implicit(y^2=x^3-2*x+1, x, -4,4, y, -4,4) because of the equal sign.?

On a related note, I also find matlab's convention to indicate line specs extremely handy, especially in "multiplot" (hold) interactive mode... For example, 'r:' means red dotted line, and 'b--' means blue dash line, 'k-.' means black dash dot, etc.?A command using this looks like: plot(t,sin(t),'-.r').

Thanks again.

You can take a look at example "Multiple windows" in

? terminal

2) A related functionality is the ability to plot several functions on the same axis?sequentially, possibly within a loop.
? multiplot_mode
