Need sample code to draw Histogram Series in VC++ (MFC)

Narcís · Post by **Narcís** » Fri Jan 04, 2008 11:12 am

Hi Frances,

Thanks for the information.

Now I am okey to draw line series using TeeChart . but I am not able to understanding how I will draw Histogram using TeeChart .

I am having four coordinates i.e left , right , top , bottom to draw histogram but I don't know which are the methods or properties required to draw histogram series. also I don't know how to fill color in histogram series.

So could you please send me some sample code for MS VC++ technology which contains example to draw histogram series using Teechart activeX .

Ok, you can create and populate histogram series like this:

Code: Select all

	long series1;	
	series1 = m_Chart1.AddSeries(scHistogram);
	
	m_Chart1.Series(series1).SetColor(RGB(255,0,0));

	for	(int i=0; i<10; i++)
	{
		m_Chart1.Series(series1).AddXY(i,i,"",clTeeColor);
	}

You had suggested me to use following,

For further information about VC++ applications with TeeChart please read Tutorial 15 - MS VC++ Applications and have a look at the examples at C:\Program Files\Steema Software\TeeChart Pro v8 ActiveX Control\Examples\Visual C++. I also recommend you to have a look at Tutorial 7 - Working with Functions

but I don't have these materials on my machine .

As I told you before, to obtain full documentation and examples you need to download the full TeeChart Pro v5 ActiveX installer at our customer download area.

I am trying to draw histogram using TeeChart proActiveX v5. Following function I am using to draw histogram , but somehow AddXY funtion is not working properly.

void CSfxStatisticsView::DrawRect(double dLeft, double dTop, double dRight, double dBottom, int iLineWeight, COLORREF lineColor, COLORREF fillColor)
{
SeriesInfo_t* pInfo = NULL;
if (m_SeriesMap.Lookup(-1, pInfo))
{

pInfo->pHistogramSeries->AddXY(dLeft, dBottom,"",(OLE_COLOR)lineColor);
pInfo->pHistogramSeries->AddXY(dLeft, dTop,"",(OLE_COLOR)lineColor);
pInfo->pHistogramSeries->AddXY(dRight, dTop,"",(OLE_COLOR)lineColor);
pInfo->pHistogramSeries->AddXY(dRight, dBottom,"",(OLE_COLOR)lineColor);
pInfo->pHistogramSeries->AddXY(dLeft, dBottom,"",(OLE_COLOR)lineColor);

}

}

Please let me know is this correct code to draw histogram and to fill color in each bar ?

Also please let me know which are the properties need to set while drawing histogram.

Thanks in Advance

Hi Abhijit,

You'd better populate histogram series in the dialog initialization code. Then, instead of providing left, top, right and bottom you should only use X and Y values for where you want each bar being drawn (x value) and the value each bar should have (y value) TeeChart will automatically draw the polygons using this information.

Hope this helps!

Do you have any histogram sample MS VC++ code which is used to draw the polygons .

Thanks for your information

Hi Abhijit,

Have you tried using the code example I posted on this thread on 4th January?

Thanks in advance.

I have tried but didn't get any luck to draw histogram series. Can you please brief explain how that histogram works .. which are the properties we need to set to draw histogram ....

Hi Abhijit,

Using the code I posted should be enough. Do you receive any specific error message?

Thanks in advance.

Abhijit · Post by **Abhijit** » Wed Jan 09, 2008 11:35 am

I din't get any error message , but I think I am missing certain properties to set . So because of that only I am asking if you have any list of properties need to set while drawing histogram series could you please send it to me?

Hi Abhijit,

Could you please try modifying one of the examples at C:\Program Files\Steema Software\TeeChart Pro v8 ActiveX Control\Examples\Visual C++ with the code I sent and check if it works fine at your end?

Thanks in advance.

Hi Abhijit,

You're welcome, I'm glad to hear that.

Thank you very much. I wish you the best for 2008 as well.

Thanks , Last problem .. Is it necessary to set width of the Polygon while drawing histogram? if not what default value did it takes?

How that width is calculated?
