Which type of graph do you think is best for showing Flores del Mundo’s membership trends over the course of the year?
You could use a timeline to graph this data and just call out some key things from the year that you want to point out. I agree with everyone else though that a line graph would work well.
Does your answer change if you’re graphing total membership versus employee/spouse/dependent?
No, I would still make a similar graph.
Does your answer change if you want to show Eastern and Northern on the same graph?
No, I would still use the same graph type. If I went with a timeline option I would make two separate graphs. If I went with a line graph I would use different colors on the same graph to show the different zones.
