I got two charts and I use chart.SetVisible to switch between the displays. I have both colorband and annotations on both charts and the chart that got initially displayed can show the Annotations correctly, but when I switch between the two charts, all Annotations were gone. Would any please sugges...

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...

Hi, after zooming in the display, I would like to get the first and last data index shown in the chart. Would anyone please tell me how to do it with sample codes? Thanks.

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...

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.

I tried to open the projects under Visual C++\version 6\ with VS2008, and after the conversion to VS2008, the adding data arrays and drag points demo had errors when I tried to open the resource to check the dialog. The error screens are attached. I reinstalled ver2010 again and the problems remaine...

Attached is the test program that will generate the error. It is a VS2008 project. In the testView.cpp, I included two header files #include "Chart1.h" #include "Chart2.h" The error occured when I compiled it. Also, when I opened the demo project "Add data arrays" using vs2008 and compiled it, quite...

Would anyone please give some suggestions? It is really urgent.

In each of the two header files, I declared a CTChart varialbe and when I included both in a cpp, the compile error occurs.

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_...

I have tested the fixed version and it works well with all words displayed correctly. So can I distribute the file you sent me instead?

I dind't receive email other the email notification from the forum.

email sent. Thanks.

I have read the post http://www.teechart.net/support/viewtopic.php?t=6339 using CodeUTF8String, but the error still exists when I added Chinese for axis title. I am using TeeChartAX8Unicode version. The code I use is m_chart1.GetAxis().GetBottom().GetTitle().SetCaption(m_chart1.GetEnvironment().Code...

Noted with thanks.

Problem solved with m_chart1.GetAxis().GetLeft().GetLabels().SetValueFormat("0.0000");
