The bar/column chart excels at showing discrete data while comparing one data-point vs. another, while the pie chart is the classic way to show how various parts makes up a whole. Both make it easy to for readers compare values relative to each other.
What are the advantages of bar chart?
- show each data category in a frequency distribution.
- display relative numbers or proportions of multiple categories.
- summarize a large data set in visual form.
- clarify trends better than do tables.
- estimate key values at a glance.
- permit a visual check of the accuracy and reasonableness of calculations.
What is the difference between a pie chart and a bar chart?
Pie charts show how much each category represents as a proportion of the whole, by using a circular format with different-sized “slices” for different percentages of the whole. Bar graphs use a series of rectangular bars to show absolute values or proportions for each of the categories.

The usage of thin slices, which are hard to discern, may be difficult to interpret. The usage of percentages as labels on a pie chart can be misleading when the sample size is small.
What are the advantages and disadvantages of pie graph?
If too many pieces of data are used, pie chart becomes less effective. They themselves may become crowded and hard to read if there are too many pieces of data, and even if you add data labels and numbers may not help here. You need a series to compare multiple sets as this chart only represents one data set.
