Pie Chart

A Pie chart is a circular statistical graph that is divided into sectors to illustrate proportions. Each pie slice or sector represents a category and its contribution, in terms of size, to the whole.

In this example, a Pie chart with “Assignee” as a category is created to analyze Jira issues.

To create a Pie chart:

• Right-click on the ‘Priority’ column > Select View > Change > Pie.

Refer here to learn more about creating a visualization.

The following figure shows the resulting Pie chart.

Configure Pie Chart #

• Select the Pie chart and open the Visualizations Panel.

The following configuration options are available for Pie chart:

1. Data Configuration: It lets you choose columns for the following settings:

   • Category

   • Sector size

   • Color Saturation

   • Sorting

2. Visual Configuration: It lets you configure the visual appearances and interactions of the Pie chart.

   • Label

   • Legend

   • Decimal Precision for Values

   • Container Settings

   • Visual Interactions

3. Visualization Level Filters: It lets you filter the data in the visualization without impacting other visualizations.

Refer here to learn more about Visualization Level Filters.

4. User-Defined Colors : It lets you add meaning to a data point by associating a specific color to it or, differentiate a data point from the rest.

   • Colors for Individual Data Item

   • Color Saturation

Data Configuration #

• Click on the icon for data configuration options.

Categorize By #

Specify the column whose values should be displayed as categories in the Pie chart.

To change the column for the category:

1. Click on to remove the existing column.

2. Drag the desired column from the Data Panel and drop it onto the Visualizations Panel’s “Categorize By” section.

Note: You can also type the column name in the Data Panel to quickly find it.

Sector Size By #

Specify the column to calculate the size of the sectors. The sector size can be calculated using an aggregate function (COUNT, SUM, AVERAGE, etc.) applied to the given column.

To change the column for sector size:

1. Follow the same steps as shown in “Categorize By”.

2. Click on the icon to select the aggregate function.

• Aggregate functions for textual data: Count, Unique Count

• Aggregate functions for numerical data: Count, Unique Count, Sum, Min, Max, Avg

In this example, sector size is calculated based on the count of issues resolved by the Assignee.

Color Saturation #

You can use color gradients to show the progression of data from high to low values. Each sector will be colored with a shade of the spectrum between the two colors defined as ‘Minimum’ and ‘Maximum’.

To apply color gradients:

1. Drag the desired column from the Data Panel and drop it on the Visualizations Panel’s “Color Saturation” section.

2. Select the aggregate function by clicking on the icon.

In this example, notice how slices in the Pie chart reflect the gradient with light colors for low values and dark colors for high values calculated as Count (Type).

To customize the shades of color saturation, refer to section-Color Saturation Settings.

Sorting #

You can sort the slices of the Pie chart on the basis of either Sector Size or Category.

Note: By default, the Pie chart is sorted by the Sector Size.

To change the sorting order:

1. Click on icon and select the column from the dropdown.

2. Click on the or icon to select the sort order (ascending or descending).

Numeric Values are calculated from the column selected for ‘Color Saturation’ (in this example- count (Type)). You can provide custom values representing ‘Minimum’, ‘Center’, ‘Maximum’ Values.

All sectors beyond the defined range will be represented with colors defined as Maximum/Minimum respectively.

Diverging Color Scales #

1. Turn on the toggle switch for ‘Diverging’. An additional color selector for mid-range value, called Center, appears.
