Use a pie visualization to highlight proportions.
Each slice shows the relative relationship of each part to the whole at a set point in time. The larger the size of a slice, the higher the percentage of the whole it represents. Pie charts are suitable to use with both nominal and categorical data sets.
To highlight actual values, use another chart type, such as a stacked chart. Additionally, pie charts plot a single data series. If you need to plot multiple data series, use a 100 percent stacked chart.
