How to Create Pie Graphs from Data Charts - There is a wide variety of methods to display numeric or statistical data visually. Bar graphs, line plots, dot plots, scatter plots, histograms, and pie charts are some of the common ways of displaying data. Pie charts are circular graphs that use pie slices to show and compare data. Pie charts may seem complicated graphs, but they really are not. You can use these simple steps to create pie graphs using data charts. Step 1: Calculating the Angles - Pie charts are all about using sector angles to display data in the form of a pie. Therefore, the first thing to do is to use the values in the data chart to calculate the angles. If the total of the values is not provided, you need to start by totaling the values contained in the data chart. To calculate the angle of each slice you can use the following formula; (Value of the component)/(Total Value)×360˚ If the data is in the form of percentages, you can use the following formula; (Percent value of component)/100×100 Step 2: Draw a Circle - The next step is to draw a circle. You will need a pair of compasses for this step. You can choose the diameter of your choice and draw a circle. Once done, you can draw a horizontal radius at any point. Step 3: Start Drawing Angles - Using the horizontal radius as a reference point and mark the first angle. It will help you make a sector. Use the new line as a reference to mark the second angle and repeat the steps until you have divided the entire circle into sectors. These worksheets and lessons can be used to help students learn how to create a pie or circle graph from data sets.
