One of the main plots that are used for Quality Control is known as a Levey-Jennings Chart. We have been doing something similar with just the bar graphs but it would be nice if we could make Levey-Jennings plots directly within Skyline.

Basically it is a line plot of QC values with lines drawn for the mean, 1SD, and 2SD. These plots are the main ways that the "Westgard Rules" are visualized. Ideally, we would like to color certain QC points if they break a "Westgard Rule."

Hopefully Michael's SProCoP external tool solves this need well enough that it is no longer on the Skyline TODO list, but if you still envision this being more tightly integrated inside Skyline, just re-open this issue, and we will make that happen in whatever time frame you feel is required.
