Pie chart calculator plots the pie graph on the basis of the percentage of each data type in the dataset. Due to the calculation of percentages, this tool is also known as the pie chart percentage calculator which is useful for visualizing the proportional distribution of various categories for a dataset with separate slices and different colors of each category in a pie chart.

This tool makes it easier to interpret the relative significance of each category by simply entering the data values and calculating the percentages automatically with respect to the segment value of every data. The accurate pie chart gives a detailed visually appealing and allows data analysts to draw results by comparing the whole data at a glance.

## What is a Pie Chart?

A **pie chart** is a circular chart that is divided into slices or wedges, each of which represents a proportion of the whole. The size of each slice is proportional to the quantity it represents. Pie charts are commonly used to show how much of a total is represented by each category, making it easy to compare the sizes of different categories.

## The History of the Pie Chart:

The pie chart was first developed by William Playfair in 1801, although he did not call it a pie chart. Playfair called it a "circle diagram," and it was later renamed a "pie chart" in the early 20th century. Since its creation, the pie chart has become a standard tool for data visualization.

## Use of Pie chart in data analysis:

As data analysis has become increasingly important for businesses and organizations, the pie chart has emerged as an essential tool for visualizing data. Pie charts are a popular choice for displaying data because they are easy to read and understand, even for non-experts.

## How can we create a Pie Chart manually?

Creating a pie chart is relatively simple. Follow these steps:

**Step 1: Determine Your Data**

The first step in creating a pie chart is to determine the data you want to display. This could be anything from sales figures to website traffic.

**Step 2: Calculate Percentages**

Once you have your data, calculate the percentage that each category represents of the total. This can be done using a calculator or spreadsheet program.

**Step 3: Draw Your Chart**

Using a program like Excel or Google Sheets, create your pie chart. Make sure to label each category and include a legend.

**Step 4: Analyze Your Data**

Once your pie chart is complete, analyze your data to draw conclusions and make decisions. Use the chart to identify trends and patterns in your data.

## Tips for Creating Effective Pie Charts:

To create an effective pie chart, keep the following tips in mind:

**Keep It Simple:**

Don't include too many categories in your pie chart. Stick to the most important ones to avoid cluttering your chart.

**Use Color Strategically:**

Use color to highlight important categories and make your chart visually appealing.

**Label Your Chart Clearly:**

Make sure to label each category and include a legend to make it easy to understand.

**Consider Alternative Charts:**

In some cases, other types of charts, such as bar charts or line charts, may be more effective than a pie chart. Consider your data and choose the chart that best fits your needs.

## Advantages of Using Pie Charts:

Pie charts have several advantages over other types of data visualization:

**Easy to Understand:**

Pie charts are easy to understand, even for people who are not familiar with data analysis. The circular shape and simple design make it easy to see how much of a total is represented by each category.

**Good for Comparing Data:**

Pie charts are good for comparing data because they clearly show the proportion of each category. This makes it easy to see which categories are larger or smaller than others.

**Attractive Design:**

Pie charts have an attractive design that makes them visually appealing. They can be used to add color and interest to reports and presentations.

## Frequently Asked Questions

**What is the Percentages and Degrees/angles** **Formula to make the pie chart?**

The formula to calculate the **percentages** to make the pie chart is stated as follows:

`Percentage (%) = [(Frequency or number value of one data variable)/ (Total Frequency)] x 100`

The formula used to calculate the **Degrees/angles** of the given data to create the pie chart is written as:

`Angles values = (Given number/ Total number Value of Data) x 360`^{o}

** How to make a pie chart? **

To make the pie chart, find the percentage values of every number or data input by using the percentage formula and using the angle formula to find the angle value of each slice in the pie chart. After finding the Angle value of each slice then draw the pie chart by dividing the 360-circle according to the angle value of the slices and give a separate color to each slice for perfect visualization. Moreover, use our above Pie chart calculator to make an accurate pie chart by just entering the value in the given input fields.

**How to calculate probability in a Pie Chart?**

To calculate the value of the probability of any data in a pie chart then convert the percentage value of every input data segment into the decimal value divided by “100”. The percentage pie chart calculator uses these percentages to calculate the angle of each sector in the pie chart. i.e., if the percentage of the segment is **40%** then the probability of this segment is “**0.4”**.

**Is a Pie Chart the Same as a Donut Chart?**

**No**, in graphical mode both are not the same. A Donut chart is known as a variation of the pie chart. The primary difference between the donut chart has a hole in the center of its visualization graph and uses one data segment/single percentage for the graph. But both have some similarities such as both are used for the same purpose for the visualization of data and allow to see more clearly visual effects.

**How to make a pie chart with percentages?**

- First calculate the total percentage of the given data.
- Then calculate the angle size of each slice of the pie chart by using the angle formula for a pie chart.
- Finally, draw a pie chart with the use of a compass to draw a circle of 3600 and a ruler for the boundary of each slice.

Also, use our above pie chart calculator to make the pie chart of any data quickly and accurately without following any steps.
