Hello Maple Users:
I try to display a 3D Scatterplot with the command:
plots[display]({scatterplot(x,y,z)}, view = [0.5..1.5, 0.5..1.5
,0.5..1.5],axes=boxed);
As long as the vectors x,y,z are are relatively short (e.g. 250
observations (data) in each vector) I get nice 3D Scatterplots.
However, now I want to display more data and the vectors x,y and z contain
approximately 1500 observatios each.
I get the following error message:
Error, (in plots/object2plot) bad object to display symbol
Any suggestions what I should do??
Thanks...Hendrik

I really don't think the lengths of the vectors are likely to be the
problem. I just did a 2000-point scatterplot in Maple 8 with no
apparent problem:

> plots[display]({scatterplot(dat1, dat2, dat3)}, axes=boxed,
> view=[0..1,0..1,0..1]):
Your error message seems to indicate that "display" was passed something
symbolic to plot, rather than a valid plot structure. Are you sure
you didn't forget the "with(stats): with(statplots):" or equivalent?
