Radar graph
Radar graphs visualize tabular data that has one or more numerical columns. Typically, the visualized data also has one non-numerical column whose values are used as graph labels that uniquely identify each row.
A radar graph can visualize data in either of two ways:
*Row series visualization: The graph displays one radial grid line for each numeric column of the visualized data, and one trace for each row of the data. A given trace intersects a given radial grid line at a distance (from the graph’s center) that is proportional to the value of the grid line’s corresponding column for the trace’s corresponding row. A marker is displayed at the point of intersection.
*Column series visualization: The graph displays one radial grid line for each row of your data attachment, and one trace for each numeric column of your data attachment. A given trace intersects a given radial grid line at a distance (from the graph’s center) that is proportional to the value of the trace’s corresponding column for the grid line’s corresponding row. A marker is displayed at the point of intersection.
Use the valueTable property to attach data to a radar graph. Use the rowSeriesFlag property to specify row series or column series visualization.
When a radar graph is selected in the Builder canvas, the Object Class Name that appears at the top of the Object Properties pane is obj_radar.
The Object Properties panel organizes radar graph properties into the following groups:
*Radar graph: Alert group
*Radar graph: Background group
*Radar graph: Column group
*Radar graph: Data group
*Radar graph: Data Format group
*Radar graph: Data Label group
*Radar graph: Historian group
*Radar graph: Interaction group
*Radar graph: Label group
*Radar graph: Legend group
*Radar graph: Marker group
*Radar graph: Object group
*Radar graph: Plot Area group
*Radar graph: Radial Axis group
*Radar graph: Trace group
*Radar graph: Value Axis group
