how to make a pie chart in excel with group

Step 1: We add the frequency values together to get the total frequency. We will now calculate the percentage and degrees covered by each of the colors in the following simple steps.

To better explain the calculations involved in a pie chart, let us consider the example 1 above. To determine how many degrees should be covered by each pie sector, we use the following formula:ĭegree of each value =(ValueTotal value)360Īfter calculating the degrees covered by each pie, we can construct the pie chart by using a compass to draw the circle, and a contractor to measure the degrees covered by each component from the center point.

Percentage of each value =(ValueTotal value)100 When visualizing a dataset using percentage, the percentage of each value is calculated using the following formula: The portions that exist in the pie are measured as an angle of the total 360 degrees.ĭata can be visualized on a pie chart in degrees or percentages. The entire pie represents 100% of the dataset, while each sector/pie slices represents a portion of the whole dataset. In other words, the pie is divided into different slices, with each slice representing the frequency of the processes in the dataset. What is a Pie Chart?Ī pie chart is a circular graph divided into various sectors to illustrate numerical proportions. However, the amazing part is that you can enjoy multiple pizza slices while you learn about pie charts and how to create one using Excel. Unfortunately, the rest of this article may not necessarily have anything to do with pies or pizza slices. Originally created by William Playfair, this data visualization method is widely used in business and mass media. The pie chart is a graph named after a sliced pie, due to their semblance to each other. This is most likely going to be where your train of thoughts will go if you are not a data analyst, statistician, or mathematician. When you hear the word pie, the first thing that will probably come to your mind is a pizza slice, snack, or pie - literally everything else asides from a pie chart.
