All good and fine, and a sad day for fans of Michael Jackson, the king of pop as he was known as, but a sad day also for data visualizations.
Secondly, the area chart could instead have been replaced with a line graph, thus minimizing non-data pixels.
- The color scheme makes it tough to see the data clearly. Of course there are only two bars, so it is not that difficult.
- The X-axis labels are gibberish. There is no sub-title or explanation of what these numbers mean. What does "6.4k" mean? And what do the zeros at the end signify?
- The location of the vertical scale on the right is non-standard. Most often a scale is placed on the right edge when there are two axes on the graph, as in a dual-Y bar/line graph, and the left and right edges both have different scales. For example, if you were plotting sales and units on the same chart, and using the left axis for the sales and the right axis for the units data.
- Adding a fourth quibble: time series data is best visualized by a line graph.
A better graph than the first one, but with the same problems of having no vertical scale.
