A Heat Map Chart renders data as a color-coded grid, making it easy to spot highs, lows, and trends across two categorical axes. Heat maps work especially well for time-series data broken into discrete periods.
This sample combines four heat maps into a single climate dashboard for White Plains, NY. The top chart covers record high, average high, average low, and record low temperatures in both Fahrenheit and Celsius. Below it, separate charts show average precipitation in inches and millimeters, average snowfall, and the number of precipitation and snowy days per month. Each section uses its own ordinal color scale so patterns within each metric stand out clearly. Hover any cell to see detailed values in the tooltip.
Follow the step-by-step Heat Map Tutorial to learn how such charts are built. See the Heat Map documentation for all configuration options.
