Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.

When would you use a pie chart?
There are two primary use cases for a pie chart:
- If you want your audience to have a general sense of the part-to-whole relationship in your data and comparing the precise sizes of the slices is less important.
- To convey that one segment of the total is relatively small or large.
When should you use a pie chart or a bar graph?
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.
When should a pie chart not be used?
If you still feel the urge to use them, make sure you only use them for a percentage breakdown where each slice represents a certain percentage out of 100% and order the slices in size to make it easier to read. Never use a pie chart if it has more than 5 slices and never-ever make it 3D.
What is a pie chart used for in statistics?
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.
How does a pie chart work?
A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole.
What is the difference between pie chart and pie graph?
A Pie Chart (or Pie Graph) is a special chart that uses “pie slices” to show relative sizes of data. The chart is divided into sectors, where each sector shows the relative size of each value.
What is the difference between bar graph and pie graph?
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.
What’s the difference between column chart and pie chart?
CHART BASICS
Column chart: for comparing data across categories. Pie Chart: for showing the relative shares of categories in a total. Line Chart: for showing trends in a series over time. Scatter Plot: for showing the relationship between two series (given later).
What are the problems with using a pie chart to display these data?
Pie charts are typically used to tell a story about the parts-to-whole aspect of a set of data. That is, how big part A is in relation to part B, C, and so on. The problem with pie charts is that they force us to compare areas (or angles), which is pretty hard.
Are pie charts misleading?
Pie chart. Comparing pie charts of different sizes could be misleading as people cannot accurately read the comparative area of circles. 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 should I use instead of a pie chart?
Simple bar chart or Stacked bar chart
Definitely, the best alternative for a pie chart/ donut chart is a simple bar graph because in that case we only have to compare one dimension, length with more clarity and less cutter.
How do you use pie?
Word
- Click Insert > Chart.
- Click Pie and then double-click the pie chart you want.
- In the spreadsheet that appears, replace the placeholder data with your own information.
- When you’ve finished, close the spreadsheet.
- Click the chart and then click the icons next to the chart to add finishing touches:
How do you explain a pie chart in a presentation?
A pie chart divides data into separate sections to show which individual parts make up the whole. To describe the chart, compare each “slice” of the chart to the others to determine what share of the total each category has.
What is an advantage of a pie chart?
Advantages of a Pie Chart
A pie chart presents data as a simple and easy-to-understand picture. It can be an effective communication tool for even an uninformed audience, because it represents data visually as a fractional part of a whole.
How do you analyze a pie chart?
To interpret a pie chart, compare groups.
- When you interpret one pie chart, look for differences in the size of the slices.
- When you compare multiple pie charts, look for differences in the size of slices for the same categories in all the pie charts.
What is the most important aspect of pie charts and bar graphs?
The most important part of your chart is the information, or data, it contains. Pie charts represent data as part of 100 (a percentage). Each slice represents a different piece of data.
What is the difference between pie chart and Doughnut chart?
A pie chart is a circular graph that shows individual categories as slices – or percentages – of the whole. The donut chart is a variant of the pie chart, with a hole in its center, and it displays categories as arcs rather than slices. Both make part-to-whole relationships easy to grasp at a glance.
What is the main differences between a column chart and a bar chart?
Column and Bar charts are effectively the same. The difference is that Column charts display vertical columns and Bar charts display horizontal bars. On a Column chart, the values are on the vertical (y) axis, while on a Bar chart, the values are on the horizontal (x) axis.
Do you think pie charts are an effective visualization tool?
After all, pie charts aren’t evil. But more often than not, they’re not the most effective choice for visualizing your data, especially when working with many data points.
