Graph controls

[rubendegroote]

The time graph needs some more refined controls. At the very least the features of the labview graph in the old program.

• add custom flags for beam tuning events such as faraday cup in/out, starting optimization etc.
• add an optional baseline for the background to help initially finding the beam
• add ability to zoom in on the region of interest by sliding the mouse
• make the graph update itself from an .h5 file

I'll give this a shot today, think I might have found something yesterday that looks like it could do things like select a region and zoom in, but tbh I think the inherent zooming functionality of PQtgraph is more than good enough, but this looks like interesting practice.

You found the region-of-interest stuff I guess, that was also what I was thinking of.

The standard zooming is nice, but I do think the ability to only show the current starting from a certain time is needed for tuning (while still autoranging). Also the ability to select only a certain y axis range.

ye of course the more the better, we could also think of adding like custom flags in the graph, for example "FC in/out", or started optimizing voltage X etc., would be also very good if we could somehow add a function that would keep track of the background and plot a straight line through the "average" background level, this would be very useful for when you are tuning but see zero beam and then such a line would help to see if you might have gotten something above the background so you don't miss it

Very good ideas! Feel free to update the issue with these ideas.
