How to Graph a Pie Chart When the Categories Overlap

Some graphs, such as this pie chart, are displayed in three dimensions.

Graphs and charts show statistical information in a visual format. Graphs make it easy to compare data and process it quickly. You can make a bar graph to compare two or more amounts in relation to each other or a pie chart to compare parts to a whole. If categories overlap in a pie chart, you need to create a new category including both topics.

    Create a list of the items or categories you need to include on the pie chart. For an example, use expenses in a household of $575 for rent, $70 for electric, $45 for heat and $25 for water.

    Add all expenses together for a total of $715 in expenses for the month. Convert each number to a percent of the whole by dividing it by $715. Rent is 80.4 percent, electric is 9.8 percent, heat is 6.2 percent and water makes up 3.6 percent of your monthly expenses. Each section has a portion on the graph.

    Combine the two expenses you want to overlap into a single category, such as electric and heat. The new total is $115 and makes up 16 percent of the monthly expenses. The new graph eliminates two separate categories for heat and electric and links them together in a new category.


    • Not all graphs are ideal for all situations. You may be better suited to make a bar or line graph with the data. Experiment to see which type displays the data most effectively.
