plots



My friend is having this problem. He says he
is considering switching bak to GNUplot for
plotting. Are we looking at something wrong?

====

If you define a variable or function to be
plotted which contains a nonnumeric parameter 
in addition to the x variable for example, 
then Maxima hangs. For example:

F: a*3*x;
plot2d([F], [x,-5,5], [nticks,100])$

hangs up because a is not defined. Maybe this 
behaviour is different in Windows than in Unix.

A second unpleasant feature is that nticks is
predefined to 0 by the plot menu. If one leaves 
this as is, it gives division by zero.
