What is a Pie Chart?
A pie chart is a type of chart used to show how a total amount is divided between levels of a categorical variable. It is a circle divided into radial slices, with each slice representing a categorical value. The size of each slice indicates the proportion of the whole that each category level takes.
Structure and Purpose
In a pie chart, each radial slice corresponds to a single category level. The primary purpose is to visually represent the distribution of categories or values within a whole, making it easy to compare each group's contribution.
Usage
Pie charts are widely used to express metrics, illustrate percentage representation, and emphasize the proportionality of categories within a whole. They are ideal when focusing on dominant categories and the overall composition of a dataset.
Advantages
Pie charts provide a simple and easy-to-understand picture, allowing for immediate analysis and quick comprehension of information. They are effective in communicating data comparisons at a glance.
When to Use a Pie Chart
Pros of Using Pie Charts
Pie charts effectively display the composition of a whole by illustrating proportional parts of a dataset. They're best for showing simple proportions and percentage distributions, making them easy for audiences to understand.
Cons of Using Pie Charts
Pie charts can become cluttered and hard to read with too many categories. It's difficult to compare similar-sized segments. For detailed data comparison, other charts may be more effective.
Comparisons with Other Graphs
Bar charts are preferable for comparing multiple categories or showing changes over time. Unlike pie charts, bar charts handle large datasets efficiently and make it easier to distinguish between similar values.
Line graphs excel in showing trends and changes across time, offering clear visualization of data progression. They're superior to pie charts for time-series data.
Scatter plots display relationships between two variables, providing insight into data correlation. Pie charts lack the capability to represent such relationships effectively.
Conclusion
Use pie charts for simple compositions and when visual clarity on proportional data is needed. For more complex data comparisons, bar charts, line graphs, or scatter plots offer better alternatives.

How to Generate a Pie Chart in Excel and Google Sheets
Creating a Pie Chart in Excel
To create a pie chart in Excel, start by selecting your data series. For example, to chart the 2017 data series, select the range A1:D2.
Next, go to the Insert tab and click on the Pie symbol within the Charts group. Then, click "Pie" to insert your chart.
If you'd like to create a second pie chart, select the range A1:D1. Hold down the CTRL key and select the range A3:D3. Follow the same steps to insert the chart.
For customization, click the legend at the bottom and press Delete. To add data labels, click the + button on the right side of the chart and check the Data Labels box. Customize further by clicking the paintbrush icon to change color schemes or right-clicking the pie chart to format data labels by checking Category Name, unchecking Value, and checking Percentage. You can center the labels and modify the font size and color through the Font options.
Creating a Pie Chart in Google Sheets
In Google Sheets, open a spreadsheet and format your data. Enter a label or category in the first column and positive numeric data in the second column. Each row will represent a slice of the pie.
Optionally, add a label name in the first row for clarity. Ensure that every data point is positive since pie charts represent parts of a whole.
After entering your data, use the chart tools in Google Sheets to generate the pie chart.
Best Practices for Pie Charts
Pie charts are ideal for showing how individual amounts contribute to a total. Examples include quarterly versus annual sales figures. They work best with a single data series and when data values are above zero.
For readability, limit to no more than seven categories. For visual clarity in smaller values, consider other types like 3-D pie charts, pie of pie, or bar of pie charts.

What are some best practices when using pie charts?
Best practices for pie charts include adding annotations, considering the order of slices, limiting the number of pie slices, and avoiding distorting effects.
Why are pie charts often considered bad for data analysis?
Pie charts are often considered bad for data analysis because they are difficult to read, do not accurately represent quantities, and humans struggle to estimate quantities based on angles. Additionally, matching labels and slices can be challenging, and they have trouble showing small percentages.
How is the central angle calculated for each sector in a pie chart?
The central angle for each sector in a pie chart is calculated using the formula (Given Data/Total of all the data) * 360 degrees.
What are some alternatives to pie charts for part-to-whole comparisons?
