Save the Pies for Dessert: Stephen Few's articulate discussion about why we shouldn't use pie charts.Įxcel charts: pie charts: an excellent summary of the arguments for and against, with guidelines on how to use pie charts properly. Pie charts, Activities: this web page describes the process for creating a pie chart from raw data. When creating a pie chart, sort the slices from greatest to least, with the left side of the greatest slice beginning at the top, at 0 degrees. Pie charts should be displayed in two dimensions.
The complications described above, especially related to human ability to judge and compare areas, are exacerbated when pie charts are rendered in three dimensions. Even then, comparing across multiple pie charts is difficult unless they have very few slices, like the example shown above.Īdvice for USING this option (tips and traps)

In the last case, a line graph would be a better format to use.Īnother limitation of pie charts is that they do not show changes over time, unless displayed as a series of small multiples. Pie charts should not be used to show increases and decreases, numbers in each category, or direct relationships between categories in which one set of numbers depends on another. Bar charts represent data size more accurately and allow for easier comparisons between data sets. The area of the slices of pie charts better represent relative size. However, the length of bars in bar charts offer a better option to show subtle differences between categories than pie charts. Pie charts are effective for comparing a given category (a slice of the pie) with the total (the whole pie), particularly when the category is close to 25 or 50 percent. This example represents the age of program participants as proportions of a whole.Īdvice Advice for CHOOSING this option (tips and traps)ĭeciding whether to use a pie chart depends on the properties of the data. Source: Elizabeth Zelesny - In this example, the proportion of homeowners and renters for each area are represented through pie graphs. Despite that, they remain a popular type of data visualisation. Many in the data visualisation field believe pie charts are always inappropriate because of their interpretation difficulties. Limiting a pie chart to four slices results in a more interpretable visualisation.
It can be difficult to judge comparisons between slices of the pie, particularly when there are many slices or the slices are thin slivers. However, some of the advantages of visualising data are lost when figures or a separate table are required to understand the data. Additional information can be added into pie charts by inserting figures (e.g., percentages) into each segment of the chart, or by providing a separate table as a reference tool. Thus, you are asked to select the cells containing the title (file name) and footnote with source (see figure hereafter).Pie charts can provide a quick overall impression of a data set, but do not offer very detailed information. In addition to the chart titles (Exports and Imports), the PNG for the group of charts should contain the overall title describing the data (the figure title). Select both pies (select the first and press Ctrl when selecting the second pie). You can also use the Align command in Excel by selecting page layout and align on the Format ribbon to have both pies at the same level. Arrange both pies on the Excel sheet next to each other in such a way that you would like them to appear in the PNG. Please note that each pie should have his own title (for example Exports and Imports). Create the second pie chart and make the layout as above. Then open the Layout menu by clicking on the lower triangle and then select the Chart Group command.
