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.

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

Thanks Andrei,

I get a number of errors starting with:

Scatter.cpp:546 WinMetaFileDraw not declared in scope... It looks like it includes the appropriate files. Any quick ideas on what to look into?

I'm currently running the final release of 2007.1 with gcc-4.1.1 on gentoo linux.

EMF is a win32 thing not yet supported elsewhere.
I have attached a version with WIN32 platform conditionals.
Except IsMetaFile() checks, which I just removed out of laziness.
Also gcc4 didn't like mixing enum with bool (BOTTOM, TOP), so I hacked it up with #define.

I investigated EMF support for Unixes. But it is tricky as already existing libs, like libwmf and libemf, make use of Wine headers, inheriting the LGPL license that way.

PS:
Forgot to explain: I allowed myself to change "BUTTOM" to "BOTTOM" Very Happy

Very Happy

Just got it to work (I put my U++ source trees on an NTFS partition so they are the same for both Linux and XP -- for some reason writing to the NTFS partition from Linux pukes every once and awhile)...

Thanks again for the pointer!

It will have to be this weekend before I can look seriously in the code, but it looks like it has at least some of the functionality I need.

One of the reason I was looking at gnuplot was the ability to process the data on the fly (like histograms, box-wisker plots, switching between log-log, log-normal, and linear plots which we use all the time). With any luck Scatter will provide enough of the base functionality to justify writing all the other stuff Wink

Hi Andrei,

nice work!

i have two questions:
1st which license do you apply to your code? BSD?
2nd what about using DrawText with angle in Scatter::SetDrawing, so you can turn the gridLabels as needed.

I need to extend this to do a histogram of the style in the
first example figure at http://en.wikipedia.org/wiki/Histogram

My first thought is to sub-class from Scatter to create the
reguired functionality. Do you think this is the way to go?

Any suggestions would be helpful?

Actually, scatter package contains only scatter chart and pie chart types. IMO, the histogram chart could be implemented rather easy from scratch, without scatter class derivation.

Hi Andrei,

yes, it works:

	for (int i=scatter.GetPData().GetCount() - 1; i>=0; i--) scatter.RemoveSeries(i);

It doesn't work if I start from 0 and move toward the last serie. Maybe some interaction with GetCount() that is changing during the removal.
Thank you,

Luigi

To simplify your task you must use the current version of Scatter.

Scatter v0.6 features:

4 new methods (tested in "Operations" tab):

void RemoveAllSeries();

void RemoveAllFSeries();

const Vector<String> & GetPLegend() const {return vLegend;}

const Vector<String> & GetFLegend() const {return vFLegend;}

Added PopUpInfo class to show the coordinates outside of plotting area

3 new tests: Dynamic, Log and Operations

Added conditional compilation directives for WinMetafile

Thanks Andrei, this control is becoming better and better.
I've compiled the example using mingw of latest dev version and got some error that I removed as reported:

1. in Scatter.cpp
popText.SetColor(::Color(200,220,255));
instead of:
popText.SetColor(class::Color(200,220,255));

2. in Pie.h
static void DrawPie(Draw& w, Point centre, int r, int start, int alpha, int width=0, class::Color fill=Null, class::Color outline=Black,uint64 pattern=0,class::Color background=White);

(just added 'static' to remove the mismatch of declaration)

3. in testScatter2.h
scatter7.PlotFunction(f1,String("funct")+AsString(topIndex));
...
scatter7.AddSeries(s,String("series")+AsString(topIndex),true);

instead of

scatter7.PlotFunction(f1,String("funct")<<topIndex);
...
scatter7.AddSeries(s,String("series")<<topIndex,true);

Andrei, thanx for such a good control. I use it in my U++ based program.
One thing could be useful in control properties: property changing format of displaying numbers at axes tickes. Or by default we may have following:

index.php?t=getfile&id=1123&private=0

index.php?t=getfile&id=1123&private=0

Look at numbers at vertical axis of top graph. It would be good to enter something like "%.2f" to view only needed significant digits.

You may use your own format:

void FormatY(String& s, int i, double d)
{
   s=Format("%.2f",d);	
}

and apply it for Y axis

   scatter6.cbModifFormatY=THISBACK(FormatY);
