What is a stripe chart?
A graph for displaying the distribution of a category variable or a whole-number variable that uses parts of a rectangular strip to represent the frequencies for each category or value.
What colors should not be in charts?
It is confusing and distracting. Also, don't use red and green or orange and green to make comparisons on the same chart. About 10% of men are color blind with red/green being the most common form of color blindness. Orange is close to red, making these colors completely indiscernible.
