Hi, I figured people here may be more interested in this project.
I have some cool graph extensions I'm building in an open source project, which make some nice graphical overlays for XY graphs and waveform graphs in LabVIEW. I've got a github page where you can grab the code, support the project or just have a look at some of the same screenshots.
Everything updates live in the graph, so you really need to see it, to get how it all works, so here you go:

Please star follow the project if you want to see this developed and I'd appreciate any feedback or ideas to extend it further. The markers are very much IN development right now, so no where near finished, but the tools can still be seen working. THANKS!
