To present for your consideration, the absolutely cluttered plot that I just managed to generate.
I had a mentor who would often call plots such as this 'confusograms' to drive home the need to rework them. Even to the learned astronomer, the details were still hidden behind a wall of lack of labeling and overlapping lines. For the record, the plot is a combination of two sets of observations from a routine I developed. One set of lines represents the observed coronal hole open flux and area, derived from observations of the sun in extreme ultraviolet. These should pair nicely with modeled open magnetic flux and area, also plotted. But on first glance, this isn't quite apparent. In practice, to decipher a similar figure it took the previous few pages of a paper and a nearly multi-paragraph caption to explain.
I have gotten a bit better about this, however. In my early days of graduate school I had tried to condense some information down into the most easily displayable form for a graph... an animated GIF file.
I have a difficult time with information overload.
