Pie

The Pie Chart represents data as slices of a circle, where each slice’s size is proportional to its value relative to the total.
This chart is ideal for showcasing proportional relationships within a dataset.

It can be configured as a standard pie or Rose (Nightingale) chart, where slice radii or areas can vary based on value magnitude.

Use cases:

• Displaying percentage share or contribution of categories.
• Highlighting dominant or minor segments in a distribution.
• Using rose-type mode to compare category magnitude via radius or area.

Note

Use Pie Charts for proportion-based visualizations involving up to 5–8 categories for clarity.
Avoid with too many categories or for precise comparisons.

⚙️ Setup

1. Drag the Pie Chart widget from the chart library onto your designer workspace.
2. Select the chart.
3. Go to the Widget Configuration tab in the Configuration panel.
4. Under the Configuration panel tab, select the Basic Configuration option to access essential settings for the Pie Chart.
5. Select the Source from which the chart will fetch its data.
6. Map:
   • Measure — Numeric value representing the size of each slice.
   • Dimension — Categorical value determining each slice.
7. Optionally add a Date field for time-based filtering.

📊 Basic Configuration

Configuration Item	Description
Source	The data source to query for chart values.
Measure	Numeric value plotted as each slice’s size.
Dimension	Categorical value determining each slice.
Date Field (optional)	Enables date-based filtering and drilldown capability.

Note

Assign a Dimension field to split the pie into categories and a Measure to set the relative size of each slice.
