Pie graphs

Pie graphs typically show one series of data points with each data point displayed as a percentage of a whole. The following pie graph shows the sales for Stellar printers for each quarter. You can easily see the relative values in each quarter. (PocketBuilder automatically calculates the percentages of each slice of the pie.)

Figure 24-3: Pie chart example

The example depicts a pie graph titled Printer Sales. It has a color key to the left for the four quarters represented in the graph. The circle of the pie is divided into four segments whose sizes represent a percentage of total printer sales. Each segment is shaded to indicate which quarter it refers to and labeled to show what percentage it represents.

You can have pie graphs with more than one series if you want; the series are shown in concentric circles. Multiseries pie graphs can be useful in comparing series of data.
