Bad Data-ink ratio
There are a couple of elements which are not important or even warping to the graph, like: the background pattern (image), the images showing the development. These just overload the graph, so without them, the graph would be a lot simpler, and clearer.
Using nearly the same color for two different data sources (Units shipped & Chip speed) can be obscuring and misguiding.
- Lie-Factor
The Y - Axis should start at zero, and the single graphs should be aligned accending.
The X & Y - Axis is not proportionaly represented.
Example I
The two points on the average price scale "2.0" and "1.9" are on the same hight. This can not be real.
Example II
(Chip Speed) The distance between 66 MHz and 1100 MHz is just slightly smaller than between 1100 and 3000 MHz.
- Chart-Junk
The Illustrations are unnecessary, because they are nonserious.
