Y Scroll Bar

[jsexton]

I am using LabVIEW 2018 to operate a semi-automated probe station which then measures and draws a map of all the various failure modes of 80,000+ devices.  The map is plotted using an intensity graph and displays the failures as well as a heat map of breakdown voltage etc.  Since each device is unique, I would like to zoom in on a particular area.  However, I noticed that this was only possible in the x direction (show x scroll bar) and not the y?  I am unable to locate this function anywhere and I was wondering if I have missed it in an option somewhere.  I did manage to create my own version using simulated data (see map.vi attached), but if there is an option, it would be best to use the built in function.  If this is not included, maybe it can be added in a later version as it would be useful.

Many thanks

James

It doesn't look like there's an option for that, which surprises me.

If you wind up implementing your own, I'd try wrapping it up in a QControl. It would keep your diagram nice and clean and would be reusable for other projects:

Why not just use the graph palette tools already available to you?  Right click the graph, Visible items, enable Graph Palette. Then you can Zoom and pan around the data?  It would save you having two graphs of the same thing.

Bert,

It was just surprising that it was just in the x and not in the y.  Why one direction and not the other?  Thank you for your suggestion regarding the QControl.  I will look into that.

Craig,

Thank you for the suggestion.  I have used the zoom function before, but (I am probably being fussy) I preferred the scrolling bars.  It seemed more elegant and easier to control.  I will use one graph in the end, but will only zoom and scroll if required.

Regards,

James
