I also agree that a line graph would be the best option to show membership trends over the course of the year. When looking at the trends for membership vs. employee/spouse/dependent, I would set it up so that there are different colored lines for each membership type and note in the legend which category corresponds to each line. For showing the Eastern and Northern trends on the same graph, I think that having the different colored lines can still work. If we’re setting this graph with the Eastern and Northern membership trends vs. employee/spouse/dependent, I think that there can be two main colors (e.g., blue for Eastern and red for Northern). To distinguish between employee/spouse/dependent, the blue and red color gradient lines can be used for the specific membership types.
