[Dsg-hallc_epics] HV screens

[Tyler Lemon]

Hi Steve,

It's good to hear that the screens are usable. We'll look into all of the points you mentioned.

The bug (point 1) where histogram screens are replaced when a new one is open seems like something that could be resolved with the options available on how to open the screens. I'll take a look at that first this afternoon.

Best regards,
Tyler

Tyler:

I played with the CSS HV this morning and I have a few feature requests
and one bug.

1.  If I pop up a histogram for one group and then pop up the histogram
for the all group for the same spectrometer, the individual detector
histogram gets replaced by histogram of everything.

2.  On the histograms, can you make a mouse-over that will show the
channel name, epics name (or crate, slot, channel), and voltage/current)

3.  Could the histograms be resizable?  So if you make the window
bigger, the histogram size scales with the window?

4.  Could the width of the bars on the histograms be variable width.  So
a group with 16 channels has wider bars than a group with more.  It
might be nice to leave a very small gap between bars.

5.  On the all histogram it would be nice to make a different color for
each group.

To be clear, this is quite usable now.  All of the above (except) one
are just cosmetic improvements.

At some point I would like to integrate this into the repo that does the
tcl screens.  Is there a script or set of scripts that generates the
workspace files?

Thanks, Steve
