.NET Heat Map Chart

Choose the Right Data
Heat map charts work best with large datasets with a clear structure. Be sure to choose data that can be quickly sorted and displayed in a grid-like format.

Use a Palette Scheme That Makes Sense
Color is a critical element of heat map charts so using the appropriate palette is critical. For example, if displaying a temperature you should use warmer colors for higher values and colder colors for lower values. This will make the chart more intuitive to the user.

Label Your Axes and Legend
Clearly label your heat map chart's x and y axes so that viewers can easily understand the data. Also, provide a legend that explains the color scale.

Use Heat Maps to Identify Patterns
Heat map charts are especially useful for identifying patterns in data, such as hotspots or clusters.
