Radar viewer
Radar viewer (a spider chart) compares multivariate data across several dimensions. It plots numerical values of the table columns on axes that radiate out of a center: the higher value is, the further it is from the center. The values from the same table row are connected across axes with lines.
On radar viewer, you can compare the numerical values of different columns within a row and rows' values within a dataset. Radar viewer is commonly used in the comparison, decision-making, and analysis, for example, in elemental analysis in cheminformatics.
You can use a radar viewer as a standalone chart or as an inline viewer in summary column of grid.
Note: To use a radar viewer, install the package Charts.
Add a radar viewer
- As a standalone viewer:
- On the menu ribbon, click the Add viewer icon. A dialog opens.
- In the dialog, select Radar viewer.
- As an inline viewer:
- Right-click a grid viewer. The context menu appears.
- Select Add > Summary columns > Radar.
Developers: To add the viewer from the console, use:
grok.shell.tv.addViewer('Radar');
Initially, a radar viewer picks up the first 20 numerical columns in the corresponding table. For each column, it forms an axis and calculates the min and max percentiles (5th and 95th). As row values, percentiles are also connected across axes forming two color-filled areas.
Configuring a radar viewer
To configure a radar viewer, click the Gear icon on top of the viewer and use the Misc and Color info panels on the Context Pane.
For example, you can:
- Set the min and max percentiles by choosing their values from the dropdown lists in Min and Max.
- Toggle the display of percentiles using the Show Min and Show Max checkboxes.
- Set the background color for the percentiles' areas using the Background Min Color and Background Max Color settings.
- Toggle value labels using the Show values checkbox.
Interaction with other viewers
A radar viewer responds to the current row selection and doesn't respond to data filters.
