An area chart is very similar to a line chart except that the areas under each line are filled in (coloured), and it is possible to display them as stacked. The chart is recommended for displaying absolute or relative (stacked) values over a time period.
Adding data
- In the Widget Designer, click + Select Data to select the field(s) whose values will be placed on the X-Axis.
Typically, the X-Axis of an Area Chart is used to represent time. You must add at least one item to the X-Axis. You can add at most two items. When you add two X-axis items, the chart’s two X-Axis are combined. - In the Values area, click Add+ to select the field whose value determines the height of the area in the chart. Typically, the Y-Axis of an Areas Chart is used to represent numeric data.
You must add at least one field to Values. When you add more than one Value, then each item is represented in the chart by its own colour and area. - Break by (optional): Click Add + to select a field by which to break up (group) the data represented in this chart.
Each field added to Break By is represented by its own area in the chart and is automatically added to the chart’s legend.
This is an optional field, and operates under the following conditions:
- You can add at most one Break by field.
- The Break by option is available only when a single field was added to Values (Y-Axis).
- You can add only a single field to Values, if the Break by option was used.

- Area Types: Select how areas are represented in the widget:
- Classic: Areas overlap, meaning that smaller areas appear on top of larger areas and cover them. The colours indicate the distribution between the values.
- Stacked: Areas are stacked on top of each other and do not overlap. Hover over the columns to see the percentage distribution among the values.
- Stacked 100: Areas are stacked on top of each other (but do not overlap). The combined area is stretched to the top in order to represent 100%. This option is most commonly used when the relative distribution of the values is more important than their aggregation.
- Line Type: Select how the line appears in the widget: Straight (Default) or Smooth.
- Line Width: Select either Thin, Bold (Default) or Thick.
- Legend: Specify whether to show or hide the Legend and its position.
