How to clear a Multiplot Chart Programmatically?

Hi LabView Masters:
How can I Clear a Multiplot Waveform Chart programmatically?
I know that this option is available by clicking with the mouse during the
execution, but I need to Clear the Chart when a particular variable is
high, so it's programmatically.
I've been testing some options using the Attribute Node but I did'nt got
it.
Can you help me?
Thanks in advance for your help!

I think its the last attribute on the node.
Its called history. Write an empty array to
it.
