waveform graph x scrollbar in LV7.0?

[rickford66]

LV7.0.   Why does the Waveform Graph have a Show Scrollbar property if the scrollbar is not active?

Thanks.

Because the property is member of the Waveform Graph class and you are seeing it at edit time. It has no idea if you're using a scrollbar or not.

I'd like to use a scrollbar.  I'm using the waveform graph to display already collected data.  I'm allowing the user to rescale the time axis (x-axis) and if they zoom in on the graph, I'd like to give them the abilitiy to scroll the graph too.  Is there a way to enable the scroll control?  Thanks.

If you set the property to 'true' does the scrollbar appear?

[rickford66]

It appears but I can't use it.

I'm not seeing that in the latest version so it may be specific to 7.0

I was hoping to get 2 versions of this code, one in 7.0 and the other in 2010, but looks like it's going to be a huge hassle.  I opened it with 2010 and I still get the same behavior.  Scrollbar shows, but does not work.

Did you enable the x scrollbar by doing this or with the code?

[rickford66]

As your picture shows... let me guess, that's the wrong way.  haha

[snowpunter]

No, it's the correct way 🙂

Are you zooming in on the x axis like this? You also need to have data on the plot in order for the control to be active...
