Use Heatmaps in Salesforce Maps to Visualize Record Density

This article explains how to turn on and configure a Heatmap for a Marker Layer in Salesforce Maps, so you can visualize record density by color instead of individual pins.

Prerequisites

• Plotting a Marker Layer

Steps to Render a Heatmap in Salesforce Maps

Follow these steps to turn a Marker Layer into a Heatmap:

1. Select the Marker icon to open the Marker styles.
    
2. Select Render Heatmap. You may also want to disable the markers by turning off Render Markers. This lets you view only the Heatmap.
3. Your Heatmap should now render on the map.
4. Optional: Use Heatmap Options to quickly customize how your Heatmap appears.
5. Optional: Click the three vertical dots and select Edit to view more detailed Heatmap display options.
    
6. Select the Heatmap Options tab to view the settings below.

Heatmap Options Explained

• Radius: The radius of influence for each data point, in pixels. The recommended value for the radius is 15.
• Opacity: The opacity of the Heatmap, expressed as a percentage between 0 and 100%. The recommended value for opacity is 80%.
• Maximum Intensity: The maximum intensity of the Heatmap. By default, Heatmap colors are dynamically scaled according to the greatest concentration of points at any pixel on the map. This property lets you specify a fixed maximum, which is helpful when your dataset contains a few outliers with unusually high intensity. The recommended value for max intensity is 5, unless you assign a weighted value. If you assign a weighted quantitative value, set the max intensity to 90% of the maximum value of the field you choose. For example, if you choose Annual Revenue as your weighted value, and the maximum annual revenue value in your org is 1,000,000, set the max intensity to 900,000. If you don't make this change, your Heatmap will plot poorly. See the Weighted Value option below for more information.
• Fade heat map with zoom: Specifies whether Heatmaps dissipate on zoom. When dissipating is unchecked, the radius of influence increases with zoom level so that color intensity is preserved at any given geographic location.
• Weighted Value: Displays a dropdown list of fields on the object you're enabling a Heatmap for. You can choose any value to assign a weight to your Heatmap. By default, the Heatmap depicts the number of records in a location. Other useful options include Annual Revenue or Opportunity value. By default, higher-density areas are colored red and lower-density areas are colored black, but you can change these colors by clicking the color you want to change and choosing a different one.
• Color Gradient: The color gradient of the Heatmap, specified as an array of CSS color strings. All CSS3 colors, including RGBA, are supported except for extended named colors and HSL(A) values.
