After @David Platten's demonstration at CTUG 2016, I see that it would be very useful to have better access to turning histograms on and off.
The workflow was:
- Start with histogram plotting off, series per system off
- Start with initial filter, a few charts
- Establish what you are interested in, use the 'zoom' function on the bar charts to filter out just the high frequency ones, choose something to filter further on - just one requested procedure for example
- Turn on series per system
- Turn on histograms
It would be better to be able to make these configuration changes without leaving the page or having a second tab - so either a menu item that reloads the page or having the tick boxes in the charts options section of each page would help.
