All the graphs in HCFR are real-time; i.e., you can see the graph update point-by-point during a sweep. However, if you're manually measuring and adjusting each point, the most convenient way would be to display the normal measurement grid (where you can click on each column heading to select it), and display the gamma graph in the lower right Information window (replacing the Comments window).

Even without looking at the graph, if you simply adjust Y to match Y target based on the measurement grid, the gamma will automatically be correct.

It is not my intention to branch or fork it off. I just wanted to see if I could contribute some of my time to fix some issues, since Zoyd doesn't seem to be very active right now due to RL\time constraints.
I've signed up to SourceForge, and will send zoyd a PM to see if he'll find the time to review my changes and merge them in.

I think so too.

Been looking more into the whole Chromecast red/blue saturation sweep crash. It looks like there's a small computation bug in HCFR's RGB calculations (in REC.709 mode), which causes the ccast library to trip up.
From what I can tell, the workaround I added for Chromecast specifically shouldn't affect the accuracy of patterns\readings, so I feel confident enough to carry on with other small bits and bobs.

Yes, that seems to be the best approach. What was confusing, was probably your previous post which said

Where can people download the installation executable for your current version?

OK. After some "googling", it appears that this will help when adjusting the color control using the standard calibration disks (like S&M, DVE etc.) and use this mode instead of the included color filter.
Not so much for any sensor based calibration procedure. Why they call it one of the ISF controls is beyond me.

Right, I guess I should have made myself more clear.
I'll see if I can upload it tonight, I haven't gotten to it yet.
