Made some modifications to speed up chart calculations. Only calculations that are required by the selected charts are now carried out. References issue 217.

I don't think there is anything further that I can do with this now.

I have made some further optimisations during my work with issue #332.

[David Platten]

Further optimisation of radiographic chart data calculations. References issue #217

changed how data for acquistion-based charts is obtained. Upside: much, much faster. Downside: can't exclude Constant Angle Acquisition data from CT chart data at the moment. References issue #390 and reopens issue #217

→ <<cset 03082d4d9e03>>

[David Platten]

Revised average chart data calculations so that constant angle acquisitions can be ignored. References issue #217

→ <<cset 7c2ea1aee5ef>>

[David Platten]

Corrected a couple of omissions. Clarified the True parameter when passing to the chart calculations. References issue #217

Make calculation and plotting of histograms optional. Without these the data will be quicker to calculate.

Made calculation of histogram data optional. Huge improvement in calculation time when switched off. References issue #217

f.qs only results in duplicate studies if an acquisition-level filter value is present. So for CT, provided that the user has not filtered on acquisition protocol then f.qs can be used without any duplicates.

[David Platten]

Use fast query method for study plot data when there is no acquisition protocol filter specified (there is no issue with duplicates for this situation). Use slower method when there is an acquisition protocol filter, otherwise there would be duplicates. Removed display of average choice for mammo charts as there is no chart that this is used for at the moment. References issue #217 and issue #390

[David Platten]

Fixed problem when f.form.data['acquisition_protocol'] isn't defined when a user first goes to a page. References issue #217

This is as optimised as it is going to get for the time being.

[David Platten]

Fixing chart sorting by frequency or value that I accidentally broke a few days ago in commit 753c9ab. Added code so that the required values are calculated whether histograms are enabled or not. References issue #217
