How do I manually update a graph/chart

I have a chart on my front panel in which the data is continuously being changed.  Each loop cycle (few seconds each) I clear the chart history (property node), update the chart data, and then change the Chart range to the range that it previously had.  However every time I do this I can see (for less then half a second) the clear chart and then some segment of the new data before it shows the correct data range that I want.  Is there a way to delay graph from updating until I signal it to update so I do not see the intermediary garbage data?

 

Thanks in advance,

David

Look for the Defer Panel updates property node.  Set it to True before you do the other properties and False After.

But if you have the need to set the range back to a value it was before, it sounds like you might have the axes set for autoscaling. ??  You may want to turn that off.
