Enable CT acquisition chart data points to be split by acquisition type

[David Platten]

I've been auditing high-resolution chest CT dose levels with my live install. It would be really useful to me if the charts of DLP and CTDI per acquisition protocol could filter the data by acquisition type (axial or helical [spiral] mode). To overcome this I've had to export the data to Excel and filter it by acquisition type there. I'd prefer to be able to see a chart that does this for me directly within OpenREM.

To make this work it would need to be possible to filter the data by acquisition type.

I think this has been possible for some time, and was removed in favour of a different system in issue #856!
