Your first question: Mapleprimes search works in mysterious ways. Don't rely on it. Instead, use google advanced search, requesting google to search within: www.mapleprimes.com. It works for me.

It looks like you missed Robert's comment below (apparently posted at the same time as Scott's). Check it out.

A "filled circle" is called a disk. For a disk to look "round" you sometimes need the option scaling=constrained (though here it is unnecessary), and it is also convenient in 3D to have control over the orientation, see below:

with(plots): with(plottools):
p := transform((x,y)->[x,y,0])(disk([0,0],2, colour=red)):
display(p, axes=boxed, scaling=constrained, orientation=[45,0]);

Take it easy Christopher, it is pretty clear that Doug is referring to the original poster. This is not your thread, you know ;-)

you may need the slanted inverted comma to get the labels to print properly (Maple 13)

plots[odeplot](%%,[x,295+u(x)^6],x=0..0.05, labels=[`x`,`y(x)`]);

I confirm the behavior you observe in classic, which, if I understand correctly, is explicited in the Help menu (see the last two lines below):

extracted from the Help menu:

symbol=s
Symbol for points in the plot, where the value s is one of asterisk, box, circle, cross, diagonalcross, diamond, point, solidbox, solidcircle, soliddiamond.

symbolsize=n
The size (in points) of a symbol used in plotting can be given by a positive integer. This does not affect the symbol POINT. The default symbol size is 10.

sorry acer for hijacking your thread!

of course you are right that preferences may be set, but 1) in environments in which you do not have the ability to save preferences, it's very tedious to reset each time, 2) standard maple loads more slowly than classic, requiring an extra five to ten seconds on my dual-core state of the art machine. Assuming I open about 20 worksheets per hour of Maple use, that's over 3 minutes of time wasted, time I could more profitably use to type one message like this one.

It will incorrectly rewrite any piece of Maple code containing it, that anyone finds on the web or in course notes and pastes into Standard with its default 2D Math mode.

I strongly agree, in my view this comment applies very generally -- standard/2D ought to be as little different as classic/1D as possible. Else standard/2D and classic/1D should have very different names. The potential confusion between the two is not just a nuisance, it's impeding, believe me, the growth of Maple products. Users want as much compatibility as possible.

As I shun standard, I'm increasingly marginalized and increasingly looking for alternatives. For instance, I no longer use Maple for plots, because the classic plot graphical functions have been neglected relative to standard (I use pstricks and have occasionally gone back to excel/openoffice). The more new functionalities that don't work in classic are introduced in standard, the less Maple has to offer me...
