I'm using two sets of equations to analyze 2 different data sets.
Each set of equations contain:
1. An equation that calculates the 50th percentile mark
2. An equation that calculates the 25th percentile mark
3. An equation that calculates the 75th percentile mark
The 50th percentile equation will be the thick line in the middle that will have the
75th percentile equation above and the 25th percentile equation below.
Is there a way that I can draw two sets of these lines in different color into a single
graph?
