A random chart on Twitter made me pause to see what is actually graphed. The chart title suggested a positive correlation, but the line is actually sloping down.
On closer inspection you see that the vertical axis is “low is good, high is bad”, and the horizontal axis is “left is bad, right is good”, also the horizontal axis talks about “decline” instead of “growth”, so a positive number is actually a decline.
To analyze data, it is OK to ponder and study a chart. In a presentation of final results, not.
