Circular or limited chart buffer

Post by Lorenzo » Wed May 19, 2021 3:54 pm

I have to draw the chart of a procedure that can last several days, I don't care that all the points entered are stored in the graph, it would be enough for me to view only the most recent part, there is a way to make sure that the oldest data are eliminated gradually?
At the moment the only way I have found is to delete them via the 'Delete' command, but it is a very slow procedure!

Thanks

Hello,

The Delete method should be the fastest way to remove points. Have you seen the example here?

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