Interpret Data Values with Color and Size in Map Visualizations

You can use the color and size of a shape such as a polygon or a bubble, to interpret values in a map visualization.

  1. Create or open a project and confirm that you’re working in the Visualize canvas.
  2. Select a column and render it in a map view, doing one of the following:
    • Right-click a map-related column in the Data Element pane and click Pick Visualization, then select Map.
    • Drag and drop a map-related column from the Data Element pane to the blank canvas, or between visualizations on the canvas. On the visualization toolbar, click Change Visualization Type and select Map.
  3. Drag and drop columns to the following sections on the Visualization Grammar Pane:
    Section Description
    Color Change the color for geometries displayed in the corresponding map layer (for example, polygon fill color, bubble color) based on the values.
    Size (Bubble) Change color bubble size based on the measure column values.

    To change the size of the color bubble you’ve to drag and drop measure columns only. The size shows the aggregated measure for a specific geographic location in a map visualization.

    Trellis Columns / Rows Compare multiple map visualizations based on the column values using filters.

In the map visualization, you can also use the following to interpret measure columns and attribute values:

  • Legend - If a measure column or an attribute has multiple values, then the legend is displayed that shows values by size or color.
  • Tooltip - If you hover the mouse pointer over a color bubble or data point, then the values are displayed in a tooltip.
