Yes, this solves the thread problem. Cool. There is a new problem where some plots are not getting scaled correctly - the occupancy plots in SensorOccupancyPlotsDriver (SVT monitoring) and the occupancy/rate plots in EcalMonitoringPlots (ECal monitoring) have their Y or Z scales set to unreasonable values so you can't see the histograms. The thing these all have in common is that they are not filled in the "usual way" (Histogram1D.fill(binX) or Histogram2D.fill(binX, binY)) - these are all reset periodically and filled with precalculated values using Histogram1D.fill(binX,occupancy), Histogram2D.fill(binX, binY, occupancy) or Histogram2D.add(hist2D). Clicking on the plotted histogram resets the scale, as does clearing and re-plotting the plotter (this is what I've done, for now).

There should only be a few threads now that are used for redrawing the plots, and the timer threads no longer should pile up as the app runs. Please test this new configuration and let me know if it fixes the issue. > > Thanks. > > --Jeremy > > ######################################################################## > Use REPLY-ALL to reply to list > > To unsubscribe from the HPS-SOFTWARE list, click the following link: > https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1 > ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
