pie chart

segmented chart, diagram which shows the break up of figures or statistics in the form of a circle that is sliced into separate segments

A pie chart is a circular chart divided into sectors, illustrating relative magnitudes or frequencies or percents. In a pie chart, the arc length  of each sector (and consequently its central angle and area), is proportional to the quantity it represents. Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced.

Pie charts (the term first used by Haskell, 1922) are useful for representing proportions. Individual data values of the X variable are represented as the "wedges" of the pie.

Unlike the values pie chart, this type of pie (this term was first used by Haskell, 1922) chart (sometimes called frequency pie chart) interprets data like a histogram. It categorizes all values of the selected variable following the selected categorization technique and then displays the relative frequencies as pie slices of proportional sizes.

The multi-pattern bar plot is designed to display the same type of data as the values pie chart (see Pie Chart - Values or 2D Histograms ), however, the consecutive values are represented by the height of vertical bars (of different colors and patterns) and not areas of pie slices.

Their advantage over pie charts is that they may allow for more precise comparisons between presented values (e.g., small pie slices may be difficult to compare if they are not adjacent). This type of graph may also have advantages over regular histograms (where one fill pattern and color is used for all columns), in cases when quick identification of specific columns is desired.

The sequence of values from the selected variable will be represented by consecutive slices of the pie (this term was first used by Haskell, 1922); the size of each slice will be proportional to the respective value. The values should be greater than 0 (0's and negative values cannot be represented as slices of the pie). This simple type of pie chart (sometimes called data pie chart) interprets data in the most straightforward manner: one case = one slice.
