FastLine example

[roger]

Hello,
I am using TeeChart Pro Activex Control v7.
Can some one please provide me sample code to use FastLine series in C++. I searched it in the examples but could not find it.
-Thanks in advance

Hi Roger,

Yes, you can use FastLine series like this:

Code: Select all

	long series1;
	series1 = m_Chart1.AddSeries(scFastLine);

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

[roger]

Thank you very much

[roger]

Can some one post a run as it is example in C++ for fastline??
as i am trying to implement it but facing a lot of problems.
While addXY, and many other methods.

Thanks

Hi roger,

Which problems are you having? Do you get any specific error message? Have you seen the VC++ examples at the Examples folder included with the installation?

Thanks in advance.

Hi,
I am doing
m_graph.AddSeries(scFastLine); as per suggested in the previous example.
I get error
error C2065: 'scFastLine' : undeclared identifier
Error executing cl.exe.
I could not find VC++, FastLine example. If it is there can you please tell me which one is it?

Thanks,

Hi roger,

That's because you need to add TeeChartDefines.h to your cpp file:

Code: Select all

#include "TeeChartDefines.h"

Otherwise you should use numeric value of those constants in TeeChartDefines.h, for example:

Code: Select all

   series1 = m_Chart1.AddSeries(6);

Hope this helps!

Hi,

I had done
#include "fastlineseries.h"

And I cannot find Teechartdefines.h
And also I did addSeries(6);
but i cannot get Property Series1.XValues.Order
I found similar
m_series.GetXValues().SetOrder(loNone);
But its also giving error.

Thanks,

Hi,
Also could you help me over http://www.teechart.net/support/viewtop ... =1&t=11657

Hi roger,

And I cannot find Teechartdefines.h

TeeChartDefines.h can't be found at C:\Program Files\Steema Software\TeeChart Pro v8 ActiveX Control\Examples\Visual C++. You may need to copy it to your project's header folder.

but i cannot get Property Series1.XValues.Order
I found similar
m_series.GetXValues().SetOrder(loNone);
But its also giving error.

Most likely you get an error about CValueList no? This means you need to add ValueList.h too. This is the same for all errors of that kind.

Also could you help me over viewtopic.php?f=1&t=11657

Yes, we will have a look at this issue ASAP. We try to give a timely reply to all forums issues.

Hello,
Can you please give me an run as it is example for FastLine in C++. So that it would be easy for me to implement.
Coz we have project delivery lined up and seems that implementation of FastLine would solve many of our problems,.

Waiting for an early response.
Thanks,

Hi roger,

I already posted a FastLine example here. Have you followe my advice? Which problems have you found? Have you look at he Visual C++ examples included with the installation?

Thanks in advance.

Hi,
I added
CFastLineSeries m_series[MAX_GRAPHS];
but seems that it does not have clear method on it.
as when i do m_series[1].Clear();
it gives me error C2039: 'Clear' : is not a member of 'CFastLineSeries
so what is the equivalent method I must use?

[roger]

Hi
I am refactoring to FastLineSeries, I have done some part of it. But i am facing some problems.
I had implemented following methods in my older code so where do I get equivalent of these in Fast line series class?

m_series[1].GetAsLine().GetPointer().SetVisible(true);
m_series[1].SetCursor(crHandPoint);
m_series = m_graph.Series(0);

I get following errors for the above lines:
error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'class CSeries' (or there is no acceptable conversion)
error C2039: 'GetAsLine' : is not a member of 'CFastLineSeries'
see declaration of 'CFastLineSeries'
error C2228: left of '.GetPointer' must have class/struct/union type
C2228: left of '.SetVisible' must have class/struct/union type
error C2039: 'GetAsLine' : is not a member of 'CFastLineSeries'
: see declaration of 'CFastLineSeries'
error C2228: left of '.GetPointer' must have class/struct/union type
error C2228: left of '.SetVisible' must have class/struct/union type
error C2039: 'SetCursor' : is not a member of 'CFastLineSeries'
see declaration of 'CFastLineSeries'


Please help me!!
Thanks,

Hi roger,

Code: Select all

m_series[1].GetAsLine().GetPointer().SetVisible(true);

Here you are type casting for a Line series not a FastLine. Having said that you should use GetAsFastLine() instead. However, FastLine series don't have Pointer property so you won't be able to use Pointers in FastLine series.

Code: Select all

m_series[1].SetCursor(crHandPoint);

crHandPoint is a Delphi constant. TeeChart Pro ActiveX is a COM wrapper of TeeChart Pro VCL. So that you can use its numeric value instead:

Code: Select all

	m_Chart1.Series(series1).SetCursor(-21);

For a list of all available options: http://docs.embarcadero.com/products/ra ... ursor.html

Code: Select all

m_series[i] = m_graph[i].Series(0);

I don't have any problem compiling and running similar instructions. What do you expect to get with that?
