In the previous post, I showed a graph that supposedly shows the benefit of an active learning approach in teaching.
From the viewpoint of clear vision, this graph has problems. Let me list some of the problems I see.
- Generally, this graph has too much clutter.
- The plotting points have dots that are surrounded by circles, squares, and diamonds, with different shades. I have a hard time distinguishing the points.
- There are six overlapping lines with different shading. It is hard to understand the meaning of the lines although there are labels on the left.
- It is hard to read the labels on the left since they interact with the inward tic marks.
- The legend for the plotting points is inside the line which adds to the clutter.
- Hard to read the text label right above the x axis.
- I don’t understand the <> notation, but part of the problem is that I don’t read many physics papers.
How would I improve this display?
- I would remove much of the text from the figure window.
- I’d use simpler plotting points, perhaps using color or different plotting symbols to distinguish groups.
- The legend should go outside of the plot window.
