Radar Chart

Learn how to create a radar chart in Semaphor

Radar charts are useful for comparing multiple quantitative measures across different categories. Each category is represented as a label on the chart, while numerical measures define the values plotted along each axis.

You can create a radar chart using the following query structure.

  • The first column (categorical) is mapped to the label.
  • The subsequent columns (numerical) are mapped to the measure.
Card SQL
SELECT ship_mode, -- label
AVG(profit) as Avg_Profit, -- measure
AVG(sales) as Avg_Sales -- measure
FROM sales_data
GROUP BY ship_mode
Results
| Ship Mode      | Avg_Profit | Avg_Sales |
| -------------- | ---------- | --------- |
| Standard Class | 227.58     | 237.58    |
| Second Class   | 236.09     | 246.09    |
| Same Day       | 236.40     | 246.40    |
| First Class    | 228.50     | 238.50    |

This example shows two series of data, Avg_Profit and Avg_Sales. You can add as many series as you would like. Each series should be a seperate measure column in the query.
