How do I make use of Real-time charting in TeeCharts


I want to use Fast line charting where I can make use of live / Real-time Data.

Where the points won't simply collect inside the Chart (Chart1.Axes.Bottom.Automatic := False;), but instead maintain the axis size, and either remove them from the display (or delete them entirely), but force the points to move from right-to-left.

I have looked over this page but can only find broken code for VCL. I would like to use up-to-date FMX. http://www.teechart.net/reference/index.php

Just like the link above, many of the features or examples I have found from Standard or professional version of TeeCharts (Steema) consists of VCL code which is not compatible. What are the minor details that a Chart requires in order for continuous scrolling / shifting of Data Points


Solution

  • You can find a real-time example showing how to add points from the right in the Features Demo program shipped with the binary installer, at "All features\Welcome !\Speed\Fast Delete and Fast Pen"

    enter image description here

    In the "Source Code" tab you'll find VCL code, but it shouldn't be very different in FMX.

    We'll check what can we do with those old articles.
