hi guys, i managed to 'port' or better say integrate all the stuff that has been done to Scatter so far, so here comes a package again. i havent changed anything else besides this.

next step will be to change the public names and make a wrapper class that is API compatible to current Scatter, if that makes sense.

after that i will start to include the ideas described above..

cheers

to show what i mean, here is my current diagram, code is bit patchwork, because i was not too experienced both in coding and Upp , so this is beginners level Smile

use DiagramTest

CMeter: a metering / progressbar / value bar setter with mouse, adjustable alignment and appearance (to some way)

CDiagram: base diagram class, supports movable points, zooming (STRG + left mouse), right mouse menu, moving (SHIFT + left mouse), autoscrolling of grid, auto scaling of grid (a bit different to Scatter) and maybe some more stuff. the code is not very cute though. thats why i prefer to switch / port to Scatter, i like the API much better.

FilterDiagramBase: some special diagrams for parametrising equalizers, crossovers, limiters etc.. this is what CDiagram also can be used for, to have a visual representation *and* parametrising in 1 diagram, play around, inspect the code.

the most usable of them is probably CMeter.

ah, it also supports zooming in a different way:
SHIFT + right mouse + moving left = zoom out, move right = zoom in Smile
Scatter based on Callbacks [message #30206 is a reply to message #27257] Wed, 15 December 2010 16:19 Go to previous messageGo to next message

hey all,

just came up with the idea of further parametrizing plot function, but this leads to usage of callbacks, instead of function pointers. what about that?

current case:
XY para4(double t) {return XY(0,-0.25+0.5*t);}
	scatter3.PlotParaFunction(para4,"VLine",LtRed,6,2);

this lets you calculate x and y separated, but what if one wants to specify some parameters, constants etc..?

here Callbacks can be a great deal.
example for a THISBACK, but also thinkable with general static fcuntions with arbitrary signature. as long as Callback1<float> for t is yielded, it alright.
the additional parameters would be stored in CallbackAction anyway.
XY para4(double t, int a, float b) {return XY(a,-0.25*b+0.5*t);}
	scatter3.PlotParaFunction(THISBACK2(&para4, 12, 34.2) ),"VLine",LtRed,6,2);


i think Callbacks are much more powerfull here than simple function pointers, though the latter are faster, a neglactible bit..

Hello Kohait00

I do not understand well how to call the callback function from inside PlotParaFunction() with the fixed arguments and the variable (t).

There is of course other awful options like including a pointer to a function or a simple callback plus a Array of Values. However yours looks much better Smile.


Best regards

the good thing is, that you wont have to deal with the extra parameters at all Smile since they are simply handled/stored by the CallbackAction (inside the Callback) itseld, Scatter wont even see it, it still thinks it has only a Callback1<float> and calls it like that. the Callback itself will complete the call supplying the additional parameters himself..

i'll try to make a quick demo in Scatter..

here comes a version, it includes only the very few changes needed. i didnt pay attention to make PlotFunction and PlotParamFunction

meanwhile i found out that parametrizing static functions is not yet supported for more than one param. but with THISBACK it works.

just take a look at the Test package.

i'll try to provide the extensions for Callback soon.

Hello Kohait00

I have done some changes to your code so that it is compatible with existing one Smile Smile.

cool

i'm on extending regrouping Callback code blocks, to have them bit more overviewable. i'll post it later, with that, even static parametrized function callbacks are possible.

i've posted the callbacks changes
http://www.ultimatepp.org/forum/index.php?t=msg&goto=302 32&#msg_30232

with them, it's possible to use

scatter3.PlotParaFunction(STDBACK2(para1p, 4.0, 0.25),"Circle",Yellow,6,50);

para1p beeing a non thiscall with 2 additional parameters

i'd do this instead for the old api, not to have to hassle with it in the code, simply map old api to new api like that..

	inline static void PlotFuncCB(double& y, double x, double (*f)(double)) { y = f(x); }
	void PlotFunction(double (*f)(double),const String& legend="", const class::Color& fcolor=Green,const int& weight=6)
	{
		PlotFunction(callback1(&PlotFuncCB, f), legend, fcolor, weight);
	}

	inline static void PlotParamFuncCB(XY& xy, double t, XY (*pf)(double)) { xy = pf(t); }
	void PlotParaFunction(XY (*pf)(double),const String& legend="", const class::Color& fcolor=Green,const int& weight=6,const int& Np=100)
	{
		PlotParaFunction(callback1(&PlotParamFuncCB, pf), legend, fcolor, weight, Np);
	}

Hello Kohait00

I agree. It looks better.

Hello Kohait00

New code is not compatible with old one. See the callback functions:

double funct1(double x)			{return (x*x);}	//Old
void funct1(double& y, double x)	{y = (x*x);}	//New

dont quite get you here..the provided test application is working with both or isnt it? here comes a fresh rar file, maybe i made some mistake in packing.

this one is my current test package, where both old and new api work..

make sure to use the Callback improvement for this ..see in anther thread ..

Hello Kohait

The code in bazaar.rar is the same reported:

double funct1(double x)			{return (x*x);}	//Old
void funct1(double& y, double x)	{y = (x*x);}	//New

So the problem remains Sad.

are you sure you have opened the right archive?

this is inside the above bazaar.rar


//old syntax
double ofunct1(double x){return (0.5*x*x-5);}
double ofunct2(double x){return (-0.5*x*x-5);}
double ofunct3(double x){return 3;}

//new additional syntax
void funct1(double& y, double x){y = (x*x);}
void funct2(double& y, double x){y = (-x*x);}
void funct3(double& y, double x){y = 0;}
void funct1p(double& y, double x, double a, double c){y = a*(x*x)+c;}
void funct3p(double& y, double x, double m){y = m*x;}

class Tab2 : public WithTab2<ParentCtrl> {
public:

	typedef Tab2 CLASSNAME;

	Tab2();
};

Tab2::Tab2()
{
	CtrlLayout(*this);	
	HSizePos().VSizePos();
	scatter2.SetRange(12,60);
	scatter2.SetXYMin(-6,-30);
	scatter2.SetMajorUnits(2,10);

	scatter2.PlotFunction(&ofunct3,"X Axis",Cyan,18);
	scatter2.PlotFunction(&ofunct1,"x^2", Color(28,85,255),6);	
	scatter2.PlotFunction(&ofunct2,"-X^2",Cyan);		

	scatter2.PlotFunction(STDBACK(funct3),"X Axis",Green,18);
	scatter2.PlotFunction(STDBACK(funct1),"x^2", Color(28,85,255),6);	
	scatter2.PlotFunction(STDBACK(funct2),"-X^2",LtRed);		

	scatter2.PlotFunction(STDBACK1(funct3p, 3.0),"X Axis",Green,18);

	for(int i = 0; i < 5; i++)
		scatter2.PlotFunction(STDBACK2(funct1p, 2.0*double(i)/10.0, -10.0+double(i)),"a*x^2+c", Color(28,85,255),6);
