Real time graphics

Post by MWeingarden » Thu May 28, 2015 3:50 pm

I am running TeeChart Pro V2014.12.140923 32Bit VCL with Rad Studio XE7, using C++.

I am trying to run real time graphics with scrolling the data across the chart. I am following your example in the articles but am having difficulty. I am updating the graph every 200 msec, and am deleting the number of points equal to what was added in the last interval. When I query the last point in the series, I am not getting the same X value as what was last added. The graph is not updating smoothly.

Can you offer any suggestions?

Thank you.

Hello,

How are you querying the last point in the series, and how are you adding the values?

In general these are the main tips to improve the performance in real-time charts:

If you still find problems with this, please try to arrange a simple example project we can run as-is to reproduce the problem here.
