Hi!

Below you can see my first attempt to make a simple control for plotting data and functions. Certainly, many improvements are possible and any suggestion is welcome.

To test it unzip Scatter.zip in MyApps folder and open TestScatter package. I tested it in Windows, 610-dev3.

A small bug: you should place w.End to "close" w.Offset at the end of Paint method, otherwise it kicks assertion...

Nice work. But _maybe_ it should have little bit finer modularization, decoupling painting from Ctrl?

I've already fixed the bug.(Current version has many impovements.)

Thank for suggestion. I intend to use DrawingDraw for painting to allow printing.

Looks great, thanks.

I had to change the following:

Konstruktor DrawExtension()

	DrawExtension()
	{
//		Draw::Draw();
	}

and changed function parameter 'XY & point' to 'XY point' in a few functions.

Tested on WinXP, 611-dev4.

Hello, Matthias!

Thank you for testing Scatter Chart!

Have you made the modifications to elude compilation errors or for code optimisation?

I got an error about calling protected constructor.
And I got errors on function calls with XY(a,b), complaining about having type XY instead of XY&.

My compiler is gcc-4.1.1.

I tested Scatter only in MSC71.

Yours modifications are useful for GCC users.

Thanks.

BTW, I had to also delete your library defintions for the Scatter package.
The required libraries should already be included by the used packages (CtrlCore etc.).

Very nice. I feel happy that number of capable U++ programmers seems to grow quickly now Wink

Comments:

Maybe instead of XY, I would use Pointf (in fact, even

typedef Pointf XY;

would work here Smile

Smile

Capitalisation of plotFunction and some of other methods seems inconsistent with both rest of class and U++...

Using Win32 API is generally OK, but causes cross-platform problems. I think it should be possible to implement DrawPie and DrawRoundRect using existing primitives (second one is primitive, DrawPie is somewhat harder, but hey, you are drawing cubic splines there, so you can do it Wink

Also, Print preview is off, most likely wrongly placed (see the right edge).

Shocked

Definitely, I will use Pointf type.

Necessary, but I don't read too well your hint. Could you give me a piece of advice?

I will try.

Only on screen; on paper (or PDF) is OK.

Thank you very much!

If there is no special reason, I would use "PlotFunction"

Yes, but should be OK even on the screen.
