Deletion of the data that you have added to the chart

You have to add the data through the cluster to the chart (waveform graph).

The data you want to display in the graph, but only about 1,000, but I would like to delete from the old data in the order if it exceeds 1,000,
Any way do you have?

Currently, it is not be deleted, the number of data will stop is quite a lot to be processed.

Nice to meet you

How is your code set up? The graph data is a waveform with a certain size array of points. So you can work with that array and the t0 value to get your new graph

 

It sounds like what you want is a Waveform Chart. Give that a try instead of a graph.

Cheers

Don't do something as silly as saying 'chart (waveform graph)'. A chart and a graph are two distinctly different objects and you need to determine which one you are using and then provide that information.

A chart has a history length hat you define. This history had a default of 1024 points and you normally write one point at a time to a chart. Once the history length is reached, old data is deleted and the new data is appended to the end.

A graph has no history or maximum. You typically write an array at a time to a graph and the new array overwrites the previous array. You have to use something like the Build Array with shift register to append.

So, what are you actually using'
