C++ MFC MSChart

Hi, you mean multiple charts or multiple lines on one chart?

if you're talking about multiple lines, thats simple, here's an example of multiple lines (2) in one chart:

        COleSafeArray saRet;

	DWORD numElements[] = {360, 4}; 

	saRet.Create(VT_R8, 2, numElements);

	long index[2] = { 0 , 0 };

	double value = 0;
	double vx = 0;

	for(long i = 0; i < 360; i++)
	{
		// curve 1
		index[1] = 0;

		vx = i;

		saRet.PutElement(index, &vx);

		index[1] = 1;

		value = sin(i * 0.35);

		saRet.PutElement(index, &value);

		// curve 2
		index[1] = 2;

		saRet.PutElement(index, &vx);

		index[1] = 3;

		value = - sin(i * 0.35);

		saRet.PutElement(index, &value);


		index[0]++;
	}

	m_chart.put_ChartData(saRet.Detach());

Cheers

thnx for reply....but m_chart.put_ChartData(saRet.Detach());....put_ChartData is not available in mschart...

Did you make the wrapper for the class?

Try to use:

#import <msdatsrc.tlb> no_namespace
#import <mschrt20.ocx> no_namespace

Then make a member variable for the chart, via Resources Dialog Designer, by assigning the chart to the class wrapper, something like CDMSChart class.

Cheers,
