Pie charts
You can use a pie chart to show the relationship of parts to the whole. Data in columns or rows on a sheet can be transformed into a pie chart.
Pie charts show the sum of the items in one data series
and the proportion of each item to the sum of items. In a pie chart,
the data are displayed as a percentage of the whole pie.
You can use a pie chart in the following
cases:
- You have only one data series to display.
- The categories represent parts of the whole pie.
- None of the values are negative.
- Almost none of the values are zero values.
