Pie
Also known as a Circle chart, the Pie chart is used to illustrate relative proportions and percentages of a whole data set. Pie charts illustrate information at a point in time, so it is not useful for visualizing trends or change over time.
The pie chart should give you a visually clear answer to your compositional questions; for example, the chart in this examples clearly tells us how spending is spread across departments. Avoid using too many pie slices that can be hard to decipher. Consider provide value labels on the chart for precision.
The Pie Chart Styles tab allows the designer to customize data labels, the legend, and the pie piece colors.
In the Data Configuration wizard, we can see that the dimension (represented by pie pieces) is "Department", while the metric, or value of those pie pieces, is summing the "GrandTotal" field from all Submissions, and displaying the value rounded to the nearest dollar.
The filter ensures only Submitted and approved orders are included in the data set. It also works with the "StartOfPeriod" and "EndOfPeriod" filter controls on the dashboard, which allows the user to alter the data set at run time.
Donut
A Donut chart is very similar to a Pie Chart, except the center is cut out. Like a pie chart, is used to illustrate relative proportions and percentages of a whole data set. However, generally donut charts work better with fewer categories than pie charts. This will allow the viewer to easily differentiate between the arc lengths to see the relationship between the categories and to the whole.
Donut Chart Styles and Data Configuration are similar to Pie charts.
The Dimension is the categories represented by the different arc colors on the donut, while the Metric determines the size/length of those arcs.
In this example, we have filters to narrow the data set to just those where the "ManagedVendor" T/F control is unchecked, or "is false."
