4. Definition A Pie Chart is a circular chart which is divided into sectors in which the area of each sector represents the size of the data. It is also known as circle graph. Remember that there are 360 degree in a circle so each group in the pie chart will be a proportion of 360 degree.

5. What Is a Pie Chart? What do you think of when you hear the word 'pie?' You more than likely think of the delicious dessert with a flaky crust and the filling of your choice. A 'pie' is certainly different than a 'pie chart,' although, oddly enough, both can be divided up into slices. A pie chart displays data, information, and statistics in an easy-to-read 'pie-slice' format with varying slice sizes telling you how much of one data element exists. The bigger the slice, the more of that particular data was gathered. Let's take, for example, the pie chart shown below. It represents the percentage of people who own various pets. As you can see, the 'dog ownership' slice is by far the largest, which means that most people represented in this chart own a dog as opposed to a cat, fish, or other animal.

6. Uses of A pie chart The main use of a pie chart is to show comparison. When items are presented on a pie chart, you can easily see which item is the most popular and which is the least popular. Various applications of pie charts can be found in business, school, and at home. For business, pie charts can be used to show the success or failure of certain products or services. They can also be used to show market reach of a business compared to similar businesses. At school, pie chart applications include showing how much time is allotted to each subject. It can also be used to show the number of girls to boys in various classes. You can also use pie charts to see how much money you spend in different areas.At home, pie charts can be useful when figuring out your diet. There are many applications of pie charts and all are designed to help you to easily grasp a bunch of information visually.

7. When to use a pie chart A pie chart is best used when trying to work out the composition of something. If you have categorical data then using a pie chart would work really well as each slice can represent a different category. A good example of a pie chart can be seen below. Another good use for a pie chart would be to compare areas of growth within a business such as turnover, profit and exposure. A pie chart is a circular graph that is broken down into segments (i.e slices of pie).These segments represent each category's contribution to display parts of a whole. So if your data does not represent this then you should choose another chart. Also when there are similar sized categories, it can be difficult to interpret, so keep that in mind. Although they are very aesthetically pleasing and easy interpret and very powerfu

8. Types of pie chart TYPES : 1. 2-D Pie > Pie, Pie of Pie, Bar of Pie 2. 3-D Pie 3. Doughnut USAGE: Pie chart is used to show data in proportion. It is used to display contribution of each value (slice) to a total (pie) The 2-D Pie used to show the proportions of a whole. It is used when numbers equal 100%. The chart contains only a few pie slices (many slices make the angles hard to estimate).

In pie of pie we can take some values from first pie and combine them in second pie to make smallSplercentage more readable or highlight the value in second pie.

In Bar of pie we can take some values from first pie and combine them in stacked bar to makessmall percentage more readable or highlight the value in stacked bar .The illustration of Bar of pie >> 1st Qtr2nd Oer3rd Qtr4th Qtr

10. The 3-D Pie used to show the proportions of a whole. It is used when numbers equal 100%. The chart contains only a few pie slices (many slices make the angles hard to estimate).

12. Tips to be considered 1. On a pie chart, although the axis is not apparent, it does have one. It is in fact the perimeter of the circle that serves as the axis. 2. A pie chart only really works well when you only have one set of data. 3. If this is the case then you should stay clear of a pie chart as each segment is equal to its value then when totaled equal to the whole, so using negative values can be rather confusing. 4. Useful for displaying data that is classified into nominal or ordinal categories. Generally used to show percentage or proportional data. Try not use any zero values, as they cannot be represented. 5. It is best practice to never have any more than 7 categories as it becomes harder for the eye to distinguish relativity of size between each section.

13. How to read a Pie Chart 1. Reading a pie chart is as easy as figuring out which slice of an actual pie is the biggest. 2. Usually, you have several bits of data, and each is pictured on the pie chart as a pie slice. 3. You will see that some data have larger slices than others. 4. So you can easily decipher which data is more important to your audience than others.
