How go access data in chart's history

[VI_Joe]

I want to be able to:

1. display analog data on a chart,

2. stop the chart from being updated,

3. take the data in the chart's history,

4. filter the data from the chart's history, and

5. refresh the chart with the new data

Can someone please provide guidance on how to do steps 3 and 5?

For #5 above, I want the chart screen to be updated instantaniously (not scrolled as with the initial data display).   

Thanks in advance.

The Property node "History" will when read return the entire chart history or when read reaplace the previous history with the data you pass to it.

Hi VI Joe,

given the 5 points you want to achieve I would rather suggest using a graph instead of a chart.

Then you can have to do your own buffering (in a shift register!?) with the advantage to have full control over the buffered data...

Thanks for the great advice!
