" We think they tried to say something simple, but ended up saying very little.
What is the message of that chart?
Investment went up and down, number of deals has varied, what about the average disclosed deal size? What is it they try to get across?
It appears that they have indexed each variable to 100 = 2001, and hence all three vertical scales are percentages. This is a rare instance where superimposing the first two lines on the same chart would prove insightful (the third line is a derivative of the other two). Indexing harmonizes the scales therefore the superimposed chart works with only one vertical axis.
