Polar Charts plot values around a circular axis rather than a straight one.
Radar Charts Copy Link
Radar Line Chart uses lines on a radar layout to compare multiple variables at once.
Radar Area Chart fills the area on a radar layout to emphasise coverage across dimensions.
The example below compares three jackets across six rated attributes. Each jacket is a field in the Radius slot, so each draws its own series.
Radial Charts Copy Link
Radial Column Chart arranges bars in a circle, which suits cyclical or categorical data.
Nightingale Chart uses sectors of varying radius to emphasise differences in value.
Radial Bar Chart uses concentric circular bars for compact category comparisons.
The example below plots orders for each day of the week in all three. In Store and Online are separate fields, so each day has two series.

The categories go around the circle on most Polar Charts, and the values extend out from the centre. The Radial Bar Chart is the other way round: each category is a ring, and its value sets how far the bar runs around the circle. Its slot names are swapped to match.
| Slot | Required | Accepts | What it does |
|---|---|---|---|
| Angle (Radial Bar Chart: Radius) | Yes | One category | Places one category for each value of the field. |
| Radius (Radial Bar Chart: Angle) | Yes | One or more numeric fields | Sets the size of each category's point, bar or sector. Each field adds a series. |
| Legend | No | One category | Gives each value of this field its own series and colour. Not offered on the Nightingale Chart. |
| Tooltip | No | Any fields | Shows the fields in the tooltip without plotting them. |
In the Radial Charts example above, Day is in the Angle slot, and In Store and Online are two fields in the Radius slot. On the Radial Bar Chart, the same fields are in the Radius and Angle slots respectively.
Legend Copy Link
A Legend splits each numeric field into a series for each value of a category. Use it when the values to compare are rows in the data, such as one row per region, rather than separate fields. The Nightingale Chart has no Legend slot.
The example below has Region in the Legend slot of every chart. The left column has one field, In Store, so each department has one series per region. The right column adds Online, so each region has a series for each field. Each row is one Widget: Radar Line, Radar Area, Radial Column and Radial Bar.
See Group By Legend for how the series are named and coloured.
Tooltip Copy Link
Fields in the Tooltip slot appear in the tooltip when you hover over the chart, but are not plotted. Use the slot for context that would clutter the chart, such as the revenue behind each day's orders.
In the example below, each column shows the orders for a day of the week, and the Setup tab is open beside the chart. Hover over a column to see its Revenue and Returns, which are in the Tooltip slot.
Format Copy Link
Polar Charts have these settings of their own on the Format tab, beside the title and appearance settings every chart has. Your developer can change the defaults shown.
| Setting | Where | Default | What it does |
|---|---|---|---|
| Legend | Elements | Off | Shows the legend. Position places it around the chart, at the bottom by default. |
| Data Labels | Elements | Off | Shows each value on the chart. Font and Color change the label text. |
| Segment Borders | Elements | Off | Radial Column, Nightingale and Radial Bar Charts only. Draws a border around each bar and sector. Width and Color change the border. |
Segment Borders separate neighbouring sectors, which helps when they share a colour. The border is 1 pixel wide and matches the page's Widget background colour until you change it.
The example below shows each setting turned on in its own chart, over the same data. Data Labels are on a Radar Line and a Radial Bar Chart, Segment Borders are on each of the three charts that offer them, and the legend is moved to the right on a Radar Area Chart. The Radial Bar Chart with Segment Borders plots In Store only.
