Calendar heatmaps

CDP Data Visualization enables you to create Calendar Heatmap visuals. A Calendar Heatmap uses colored cells, typically in a monochromatic scale, to show relative number of events for each day in a calendar view. Days are arranged into columns by week and grouped by month and years. This enables you to quickly identify daily and weekly patterns, and to recognize anomalies.

The following steps demonstrate how to create a new calendar visual on the SFPD Incidents dataset, based on data previously imported into CDP Data Visualization from the datafile.

For an overview of shelves that specify this visual, see Shelves for calendar heat maps.

  1. Start a new visual based on the SFPD Incidents dataset.
    For instructions, see Creating a visual.
  2. Select Calendar Heatmap in the VISUALS menu.
    The shelves of the visual changed. They are now Date (mandatory), Measures (mandatory), Tooltips, X Trellis, Y Trellis, and Filters.
  3. To show specific items, populate the shelves from the available fields (Dimensions, Measures) in the DATA menu.
    1. Under Dimensions, select date and drag it to the Date shelf.
    2. Under Measures, select Record Count and drag it to the Measures shelf.
  4. The field on the Date shelf should have a calendar icon to indicate that it is in the Date/Time category of data types. If the field is not automatically recognized as a date data type, convert it.
    On the Date shelf of the visual, click the date field, select Date/Time Function > Date.
    The default calendar heat map visual appears.
  6. Change the title of the visual to SFPD Incidents - Calendar Heat Map.
  7. Click SAVE at the top left corner of the Dashboard Designer.
