The Defer Panel Updates property doesn't have effect when selecting autoscale from the graph palette of a waveform chart i.e. the chart is updated after an autoscale even if the property is set to true (see attached example vi).
Is this a known bug for Labview 2009? Is there any workaround?
Thanks

A quick search does not show anything. I've reported this here.

Hi Paolo,
I think you could use the YScale.Scalefit property instead of the ActivePaletteTool property.
Using this property set to 1 (Autoscale once now) the behaviour is the same you described, but setting it to 2 (autoscale) it behaves correctly; so I think that this is expected behaviour, just it depends if the autoscale forces an update of the control now or not.
Have a look at the attached VI.
