Graphs and mouse

Status: New

Add the ability to zoom in and out of any section of a graph using the mouse scroll wheel natively in LabVIEW. Today when we want to see more detail on a computer, we simply move our mouse to a section of the screen and then holding a modifier key like Ctrl we roll the mouse to zoom in for more detail.

 

I've created an example that performs the actions I would like LabVIEW to do natively.

Would love this ability without programming.  Would like extend it with 'Click and hold' to to change the cursor to a hand to drag the graph content left and right or up and down.

It is my understanding that these objects are for all practical purposes stagnant.

The last fix I am aware of was adding a legend scrollbar position property which I obtained by pure chance meeting with one of the developers on this forum (on an unrelated thread). This lack of property, BTW, qualified as a bug to me, but good luck with escalating a bug report in LabVIEW unless a developer is badly affected by it.

There seems to have been a brief period where NI pushed for the picture-based plots (at least, based on the number of examples that use them). But those are even less developer-friendly (you have basically to redevelop the whole thing from scratch).

I vote for your idea even though my mouse wheel events are not even recognized by LabVIEW (probably because I am running it within a VM...).
