To magnify a picture, the artist must increase both height and width to
avoid distortion of the image. By increasing both the height and width of
the Dyson vacuum, it appears to be 4 x 4 = 16 times larger. Remember a
bar graph should have bars of equal width-only the heights of the bars
should vary. Replacing the bars on a bar graph with pictures is tempting,
but it is difficult to keep the "bar" width equal without distorting the

Figure 10.6 is a pictogram. It is a bar graph in which pictures replace the
bars. The graph is aimed at consumers shopping for a vacuum. It claims
that a Dyson vacuum has more than twice the suction of any other
vacuum. Although not clearly labeled, type of vacuum is shown along the x
axis or horizontal axis, and the y axis or vertical axis, gives the calculated
number of air watts for each vacuum. We see the Dyson vacuum (far right)
has roughly 4 times the air watts (160 is roughly 4 times 43) of the vacuum
on the far left. However, this graphic makes it appear as though there is a
much larger difference. Why is this?
