To append data in real time, AddRealtime or AddArray?

I am trying to continuously append recently acquired data (each time 2K per series, 3 series in total), and the series type I used is FastLine. To use AddRealtime, I could save the last x, and start plot the new data from x+dx. However, if I use AddArray, I had to save all the previous data and plot...

Re: Urgent: Teechart 2010 tchart.h problem

First of all, I don't have VC6. Secondly, even if I had VC6, I don't think it is acceptable to build future projects in VC6 first and convert to VS2008. Thirdly, I have been using Teechart 8 for a long time in VS2008 and everything worked fine, so I really think there is something wrong with the 201...

Re: Urgent: Teechart 2010 tchart.h problem

I could follow what you want. Would you please list what you want me to do step by step? Also, I am not sure if you are addressing my initial problem, which is the erro of redefinition of CTChart class when two header files that both include tchart.h are included in the same cpp file.

Re: Urgent: Teechart 2010 tchart.h problem

In the testView.cpp, I included two header files #include "Chart1.h" #include "Chart2.h" The error occured when I compiled it.

Urgent: Teechart 2010 tchart.h problem

I included tchart.h in two headers files that are both included in a cpp file, and when compiling, an error occured: "error C2011: 'CTChart' : 'class' type redefinition". I compared the 2010 version of tchart.h and v8 tchart. h and noticed that the #if !defined(AFX_TCHART_H__1C6F492E_029C_4867_A215_...
