Graph displays and callbacks in QuadEM

[Iain Marcuson via Tech-talk <tech-talk at aps.anl.gov>]

I am working on debugging a QuadEM, albeit one using an internal IOC.  I also want to make sure that I know how the IOC and OP are intended to function.

 

When using the standard quadEM.opi from the quadEM repo, the “(Fast)” numbers update according to the “Fast Averaging Time” parameter.  The numbers for e.g. “Current”, “Current (Sigma)”, and X Sum only update when I click the “Read” button next to the “Read data” label.  Is this the intended behavior?  I suspect it is, based on a comment in drvQuadEM, but I would like to verify this.

 

Finally, I do not see updating graphs when I look at the plots under “Time series”.  I am wondering if there is a callback I need to enable that I am overlooking.  I sometimes seem to get a single point on the graph, but nothing otherwise.

 

Thank you,

 

Iain.
