The Heatmap Chart is a visual representation of the data using colors to indicate the values.
Lexicon currently provides a series of color sets for the Experience Cloud analytics design. For the heatmap, you must use a single color value and white for the time-spots.
To improve the activities readability, you can use up to seven different circle items (bubbles) inside the chart: 0, 4, 8, 12, 16, 24, 32.
