Thank you for your suggestions of reducing the number of points plotted. I am actually doing that myself in the application, but when the user selects the highest sampling rate, I can't do any further data reduction. If you had a way to add XValues and YValues (arrays) to existing data, that should ...

I sent a simple demo through the upload page. To monitor the CPU usage, I ran Windows Task Manager and monitored the CPU usage of the process. When the program first starts running, the CPU usage stays about 12%. As data is added, the CPU usage slowly increases and reaches a steady 30% when the max ...

Thank you for your response. I have read the article on real time plotting and have already implemented the features mentioned. The problem is that I am constantly plotting the same amount of data, adding the data to the graph every 200 msec and deleting data when the 60,000 point per series is exce...

I am running the VCL Build 8.06.60902 with C++ Builder 2010 and am experiencing the same problem of CPU usage going up to 75% when a large amount of data is added to a real time display. I am deleting data, but am allowing up to 60,000 points to be displayed per data element. Has anything further be...

I am now using TeeChart VCL 8.06 in both BCB 6.0 and CodeGear 2010. Your description of using an array for adding both X and Y values allows me to code it and use the functions as described. However, I am now using it for real time graphics, where I want to add a set of data to a chart (that has exi...

Thank you.

The problem disappeared with 8.06.

I am using version VCL Pro 8.04 under BCB 6.0. When I build a simple project, I cannot duplicate the problem. The series is a TLineSeries.

Thanks

I have a graph: Graph1.PNG Graph2.PNG Graph3.PNG The first graph shows the data at 0 time to be about 0. As I drag the data to the left, a negative offset for the first point is introduced. As I drag it a little further to the left, the offset changes to a positive offset for the first point. This p...

I am charting data in real time - scrolling as per your example of charting data in real time. My data can range from 0-100%. I would like the axis->maximum not to be less than 10%, otherwise, I would like it to scale automatically. I am adding data to the chart 5 times per second. I can set the axi...

Thank you for your assistance.

I downloaded it, again, and had no problem installing the update.

The project compiled/linked without error.

Thanks again.

I was sent a link to version to try out (I do not have the source for Teechart). I downloaded the version for RAD Studio 2009. When I attempted to install it, it would not accept my license/password.

Could you please explain what you mean by source code license? I have a license for TeeChart Pro 8.0 VCL. I do not see anything on the Steema order page for 2 different versions with source/without source.

Thank you.

Can you please send me the update as well?

Thank you

In BCB, how do I set the font color of custom labels added with
CustomAxis->Items->Add(NN,"XXX")?

Thank you for your assistance.

I have defined a chart of a fixed size. I would like to be able to add a custom vertical axis to the left of the graph. I want the graph (bottom axis) length to remain unchanged. I can make the chart wider, but I do not want the bottom axis to change with the new chart size. How can I do this? Thank...
