Question

Quizplus · Accepted Answer

Major tick marks provide clear reference points on an axis, making it easier to read and interpret the data. A legend would be useful for identifying which data series corresponds to which precinct, but it would not necessarily assist with reading the scale. Colors could help differentiate between the data series, but they would not help with reading the scale. Adding more numbers might clutter the axis and make it harder to read.
