Change the "LPtoDP(T X,T Y)" function as the folowing :

template<class T> 

CPoint CScrollChart<T>::LPtoDP(T X,T Y)

{

	int nY;

	int nX;

	CRect rectClient;

	GetClientRect(rectClient);

	nY = ((rectClient.Height() * (Y-m_MinValue) * 0.95) /( m_MaxValue-m_MinValue));

	nX = ((rectClient.Width() * (X - m_pointIni)) / m_nHzRange);

	return CPoint(nX, rectClient.Height() - nY);

}



<< In your program >>

And if you want to refresh the min vertical limit textbox 

as in the demo program only in "OnNewLimits" message 

mapped function uncomment the folloing statment:

//else m_TextVerMax.SetWindowText(strTmp);

So that the whole function can looked as follow:

void CTest02Dlg::OnNewLimits(WPARAM wParam, LPARAM lParam)

{

	CString strTmp;

	strTmp.Format("%d",wParam);

	if ( (GetCurrentMessage()->message) == WM_NEWHORZLIMITS) m_TextHozMin.SetWindowText(strTmp);

	else m_TextVerMin.SetWindowText(strTmp);

	strTmp.Format("%d",lParam);

	if ( (GetCurrentMessage()->message) == WM_NEWHORZLIMITS) m_TextHozMax.SetWindowText(strTmp);

	else m_TextVerMax.SetWindowText(strTmp);

}

Problem with the .Create

nID
Specifies the chart control's ID.

What is the chart control's ID? Is is the scrollbar?
This header looks wonderfull but I can't get it running...
In the example it has value 101. Why? I can't find the reason...

Thanks for help!!

Emil,
for your help.That u have suggested is one away solution and i also find other solution
as
Create pointer
CScrollChart *myscrollchart;
myscrollchart=new CScrollChart();
this work fine

Now I have concern about memory size.
when I put four scrollchart controls having 3 to 4 lines each with 0 timer the memory uses increases drastically.And CPU usage is also 99% which affect other application's working.
So can any one suggest how to clip the control.
Window display as of size of control would be sufficient for me.

Hello, thanks for the control. It looks very useful. I am able to draw the chart, but when I do AddLine and AddData nothing happens - I can't draw any lines on the chart.
Can you give me any info that may help with this issue?
