One way to hide data in a chart is in the scale. By blowing up the scale, it is possible to conceal variation in the data. In this example, the two bar charts show the production of poisoned apples through the years of the Evil Queen’s tyranny, being year 4 the point where Snow White was hiding in the dwarfs’ house.

This chart’s vertical axis show values from 0 to 400. The number of apples produced is so small comparing to those values, that the bars almost disappear, becoming lines. It is hard to visualize even major changes. Looking at this chart, the viewers may assume the conflict between Snow White and the Queen had no influence in the production of poisoned apples.

The vertical axis on this chart, on the other hand, shows values between 0 and 8 (8 being the value of the bar on the far right). Using this scale, it is clear that the production of poisoned apples increased significantly in year 4. From this chart, the viewers may deduce that the Queen’s vendetta against Snow White affected directly the production of poisoned apples.
