Heat map in Yandex DataLens

A heat map shows the density of point distribution. Map areas are colored with a gradient ranging from green to red: the more points are grouped in an area, the closer its color is to red.

What you need to know about heat mapsWhat you need to know about heat maps

• Heat maps are used to display clusters of large numbers of points.

  Note

  If there are few points, using this type of map may distort the detected dependencies.

• A heat map is at its most effective when representing a dataset of many points within a small geographical area.

  If there are few points, their values can be expressed through the intensity of their color: the higher the value, the closer the color is to red.

• A heat map helps you find dependencies that might otherwise be hidden due to overlapped points on the map (in case of a point map).

  For example, you can use a heat map to determine the districts where customers order for delivery most often.

Creating a heat mapCreating a heat map

1. Go to the DataLens home page.

2. In the left-hand panel, select Charts.

3. Click Create chart → Chart.

4. At the top left, click Select dataset and specify the dataset to visualize. If you do not have a dataset, create one.

5. Select Map for chart type.

6. Select the Heat map (Geopoints) layer type.
7. Drag a dimension of the Geopoint type from the dataset to the layer type selection section.
8. Change the weight of the points on the heat map. To do this, drag the measure to the Colors section.
9. Optionally, update the color settings for the measure.

You can also:

• Add, rename, and delete a layer.
• Apply a filter to the whole chart or one layer.

Color settingColor setting

To change the color settings:

1. Click in the Colors section (the icon appears when you hover over the section).

2. In the color settings, specify:

   • Gradient type: Select two or three colors.
     • Gradient color: Select a color palette for the gradient from the list.
     • Gradient direction: Change the gradient direction using the icon.
   • Set threshold values: Set numeric thresholds for each color.

3. Click Apply.

RecommendationsRecommendations

• Use a heat map if your dataset has many enough points. If there are few points, using this type of map may distort the detected dependencies.
• The intensity of point and area fill on a heat map varies depending on the map's scale. Please keep this in mind.
