the bar size to update, though. <span style="font-size: 11pt; line-height: normal">

<span style="font-size: 11pt; line-height: normal;">Feature has been added. All histograms for detectors now have barsizes set by the number of channels. One note on this point: for detectors with only a few channels, like the Drift Chambers, CSS seems to limit
the size the bars can be, so the histograms for these detectors have more empty space than others.
