Example: if a pie chart of radiographic acquisition protocol frequency is requested, as well as a plot of acquisition DAP over time, the series colours between the charts should match for each protocol name. However, this isn't the case if there are certain combinations of capitalisation in use for the names.
Django's database sort puts lower case first: Chest pa Chest PA Chest PA Grid W033 Chest PA
Chest PA Grid
W033 Chest PA
For the above protocols the colour of the series in the two charts will not match.
