Howto clear a chart in running programm?

[Daniel Ewert]

My Program periodically sends data in form of an array to a waveform chart
to display the data.
I want the newer data to overwrite the older, so that always only the last
array of data is displayed.
Therefore I have to clear the actual chart, otherwise LabView puts the data
in row behind each other.

How can I do this?
I found no proper property in the property node that could help me.
Or are there other possibilities?

Thx for help,
Daniel

You wire an empty array to the chart history property node. Look at the shipping example called "How to Clear Charts & Graphs".

If you only want to display the most recent data, would it be better to use a waveform graph to display??
