Hello Ion

You read my mind Smile

. I like them.

And this?:

double Scatter::GetXByPoint(const int x){
	return (x-GetH_Border())*GetXRange()/(GetSize().cx-2*GetH_Border()-1)+GetXMin();		
}

double Scatter::GetYByPoint(const int y){
	return (GetSize().cy-GetV_Border()-y-1)*GetYRange()/(GetSize().cy-2*GetV_Border()-GetTitleFont().GetHeight()-1)+GetYMin();
}

double Scatter::GetY2ByPoint(const int y){
	return (GetSize().cy-GetV_Border()-y-1)*GetY2Range()/(GetSize().cy-2*GetV_Border()-GetTitleFont().GetHeight()-1)+GetYMin2();
}

double Scatter::GetXPointByValue(const double x){
	return x-GetXMin())/GetXRange()*(GetSize().cx-2*GetH_Border()-1)+GetH_Border();
}

double Scatter::GetYPointByValue(const double y){
	return (GetSize().cy-GetV_Border()-1)-(y-GetYMin())/GetYRange()*(GetSize().cy-2*GetV_Border()-GetTitleFont().GetHeight()-1);
}
