How to Make a Pie Chart How to Make a Pie Chart In mathematics there are various types of charts and graphs to represent the data values in the diagrammatic form. In the general life diagrammatical representation of information makes any person able to understand easily. There various types of graphs and charts, some of them are easy to understand while others can be quite tricky. Each and every type of graph or chart has a fairly specific use in a different field. From one of them pie chart is special one. Pie chart can be used to show the percentage of a whole numbers or either fractional numbers and represent percentage at a set point in time. These are the type of charts that do not show the changes over time. Pie chart plays an important role in the field where the certain activity depends in the analysis of the records. Like business world or educational field both require the analysis of the data. If we want to show the percentage of the increase or decrease in sales of the product or school students for particular time period then we can use the concept of pie chart to show the information in the diagrammatic form.

Pie chart is a circular chart which is used to show the data in the form of slices. To create a pie chart, we need to supply a value for each slice. In pie chart, it is also good to provide a name for each slice. In the pie chart there is no limit how many slices are created? But one thing must be remembered that if number of slices is very large then each should be specified by different color. In the below example let’s see How to Make a Pie Chart by the multiple steps. Example: Suppose Albert earns $48000 from his salary. He spends his salary into different household related expenses, which are given below. Create the pie chart from the following given data of Albert’s salary? a)
$ 2400 for loan
b)
$ 4800 other expenses
c)
$3840 Household expenses
d)
$5760 daily transportation
e)
$7200 bank deposit
f)
$14400 housing
g)
$ 9600 for food material
Step a) In the first step we need to arrange the available data in increasing or decreasing order. Step b) After that add all the available data,

$ 2400 for loan + $ 4800 other expenses + $3840 household expenses + $5760 daily transportation + $7200 bank deposit + $14400 housing + $ 9600 for food material _____________________________ =
$ 48000 total
Step c) In this step we consider each value as a numerator by taking each part of the data. Step d) In this step we need to convert the fractional value into a decimal value. This can be done by dividing the numerator to the denominator value. Like
Numerator / Denominator, $2400 / $48000
The above given value is the fractional form of loan amount.
