Why Are Graphics Effective?
Think about stock information. A financial reporter covering a stock for the
first six months of the year would be unlikely to simply list changes in the
trading price for each month, like this:
|
January +3
|
April +4
|
|
February -5
|
May -2
|
|
March +6
|
June -1
|
The list gives some information, but it’s challenging to see trends, make
comparisons, or draw conclusions from this list. In contrast, take a look at
the following display of the same information.
XYZ Stock Performance Comparison to Previous Months, January-June
Does the bar graph give you a better overall picture of what’s happening with
this stock? Can you easily draw a conclusion at a glance?
A graphic display is a powerful way to help readers understand and interpret
data.
