Many of the 'Radar Diagram' features can be customized including the colors, background shape, grid lines, and the positioning of the Characteristics around the radar.
To edit the 'Radar Preferences', click the '[icon name="cubes" prefix="far"] Edit Radar Preferences' button in the diagram toolbar.
From the 'Radar Preferences' modal that pops up, you may change the radar display settings including the 'Show Grid' (turning this off removes the circular background lines), 'Show Spokes' (turning this off removes just the lines that go to each Characteristic around the radar), 'Angle Offset' (sets how many degrees to rotate the radar - default is 90), 'Grid Type' (either 'Circular' as shown or 'Polygonal'), and the 'Number of Ticks' (alters the axis step count and interval).
You can also customize which colors to use for each of the 'Radar Diagram' attributes by clicking on the colorful '[icon name="pencil" prefix="far"] Pencil' button to open the color picker.
Once your settings changes are ready, click 'Apply' to update the 'Radar Diagram' with the new preferences.
With the preference changes we just made above, our 'Radar Diagram' now looks like this:
Sorting Radar Vertices
By default, 'Radar Diagram' vertices are sorted by the entity 'Number and Name'; however, this can easily be changed by clicking the [icon name="wrench" prefix="far"] wrench in the top right corner of the diagram. Expand the 'Sort Entities' dropdown header and then click the sort option you wish to apply.
The 'Name', 'Number', and 'Number and Name' options all update the radar vertices automatically when one of its entities' names or numbers are changed. However, the sort 'Manually' option allows you to place each vertex in a specific order, regardless of any of the entity attributes.
After clicking the 'Manually' option, select one of the vertices. Notice that the toolbar now has both 'Move CCW' (counter-clockwise) and 'Move CW' (clockwise) buttons.
Click either of these buttons to move the currently selected entity around to the desired position on the 'Radar Diagram', as demonstrated below:
