Adding a chart
You can add a static or interactive chart to a cell on a harness, section, or flow action form.
- Create or identify a data source.
- Add the chart control to a harness, section, or flow action.
- Configure the chart control.
- Test the chart's display and functions.
1. Create or identify a data source
2. Add the chart control
On the Design tab, from the Data display list, drag Chart to the work area. If the destination cell is not empty, the chart replaces the current contents of the cell.
3. Configure the chart control
Click the View properties icon on the cell to display the Cell Properties panel.
The panel has a preview image of the chart, and tabs where you configure the chart's display and data source.
The preview reflects the choices you make on the tabs. If you have not yet set a data source for the chart and properties for some of its elements, a static image of a chart displays. Notifications appear above the image to remind you what you need to do. These notifications vary according to the chart type you choose.
The number and names of tabs vary according to the chart type you select:
The tab has three sections: Chart, Data source, and Other/Identifier.

In the Other area, you specify visibility and loading behavior:
Visibility – Set the chart to display:

individual chart elements (such as bars, columns, lines, and pie slices) based on either
the numeric value represented by the element or the label associated with the element.
For many lists of colors you create in the sections described below, you can drag a color higher or lower on the list. A higher color takes precedence over a lower color.The sections available vary depending on the chart type you choose. They may include:
- Column, Row, Line, Area, or Wedge values – Change the color of a chart element based on the value.
- Column or Row labels, or Wedge names – Change the color of chart elements based on the label. Note that colors based on values take precedence over colors based on labels.
- Gauge colors – Specify the upper and lower values for a color range. Ranges cannot overlap.
For charts such as bar, column, area, and line that display chart elements on a grid, you can define thresholds (colored lines or regions on the grid). For gauges you can specify lines that radiate from the center of the gauge, or arcs between the values you specify.
Click Add new and, if there is an option, select the threshold type to add. Specify the value or the value range, and provide a label; then click the swatch to select a color from the color picker.
