Hi Mikhail

"labelfont" is not supported in Classic, so your command above won't work at all there. Greek characters are supported only in some parts of Classic (Classic is an old interface, remember) and can't be used where you want them. If you can do what you want in Standard I would recommend working in Standard.

The behaviour you describe about the legends was a bug that was fixed in Maple 11. You can also work around it in Maple 10 by setting the legend text on the second curve to be "__never_display_this_legend_entry". Note the two underscores at the start. Don't rely on this magic string in versions after 10, as it's not a supported feature.

If you have Maple 11 or 12 Standard interface and Alec's command above didn't work for you, and you aren't setting plotdevice, I recommend talking to tech support.

I just tried to reproduce the problem in the original post and it works fine for me. Could you try the export to WMF in a new worksheet, before trying any other export? If that doesn't work maybe you could report this to tech support, Alec?

This reversal is a known bug which may not be fixable. In general the B&W and grey options are a hangover from an earlier era when it was common to generate graphs in black and white. In these days when color is common, and even most black and white printers accept color postscript the options are really not that useful.

"none" is intended to give 2-color black and white printout.

I just loaded your ps file into my ghostview. The line looks a lot thicker than 1.5 times the axis width in my viewer, and the segmentation of the line is clearly visible (a lot more clearly than in the version Maple created). As I said, sometimes it's the viewer that controls these things. In your PDF version the horizontal axis looks thicker than the vertical, though interestingly the PDF viewer has smoothed out the curves. Is the PDF version made from exactly the sample file you posted? Also are you sure that your computer screen is set to an isotropic pixel density? Sometimes a computer can be set so that a given number of pixels can have a different physical distance in the vertical and horizontal directions.

Regarding the fonts, are you aware that font family is controllable in Maple? If you want you can set Times Roman for all the text in the plot, and that setting will be reflected in the postscript.

Roman, wouldn't that mean that some problems would never get solved as everyone would be spending all their time looking for alternative software?

What version of Maple are you working with Alec?

Hi dpaddy

When I type what you typed into Maple 12 it displays it as a fraction with 5 as the numerator and 7.3 as the denominator. This correctly evaluates to 5/21.

The 2D math input is not simply a different way of displaying the results of the same keystrokes you would use in the old 1D input - it's a new way of entering math expressions. The keystrokes "5 / 7 * 3" are interpreted as 5/(7*3), because the cursor stays in the denominator after typing 7. If the cursor did not stay in the denominator after typing the 7 then typing complex expressions into the denominator would be much more difficult. If you want (5/7)*3 then you can get it by typing a "right cursor" key after the 7. 

If you prefer to use the old style math entry you can easily switch to it.

We have to copy Maple contents in all possible formats to the clipboard, and Maple can generate some extremely large entries in the clipboard when items are copied out of it. We don't want to prevent this in general (since RTF can be a very useful format for pasting to Microsoft products). We allow the user to control whether, and how much, RTF data is sent to the clipboard.

Bring up Tools/Options and on the General tab set the "Enable RTF copy" entry to "Only for small selections". This should prevent very large amounts of data being sent to the clipboard. On the downside it will mean you can't copy large datasets into MS Office products. If the setting was already at "Only for small selections" set it to "Never". This will prevent any copying to MS Office, except for straightforward text. That should prevent Maple from locking up.

When I open this worksheet in Maple 12 I see two embedded plots. The first (the 3D) has a red line in when I open it. The second is 2D and since the red line has no X or Y variation so it shows up as a dot.

When you open a worksheet with an embedded plot in Maple 12 the contained plot should look exactly like it did when the worksheet was saved. Did you both save and open the worksheet in Maple 12? What platform are you on?

David Clayworth Maplesoft GUI Developer

Of the Maple product only the Standard User Interface is coded in Java. The mathematical methods that you are probably interested in (such as LinearAlgebra) are coded in the Maple language.

David Clayworth Maplesoft GUI Developer

That's a valid way of doing it. I would however not recommend constructing plot structures directly if there is another way to do it. The PLOT structures do not have the error handling that the commands do.
