Circular or limited chart buffer

[Lorenzo]

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?
