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."
