Highcharts - Heat Maps
Section titled “Highcharts - Heat Maps”Heat maps represent matrix data where individual values are visualized using color. They are excellent for showing patterns and concentrations across two categorical axes.
Key aspects of heat maps include:
| Sr. No. | Feature / Description |
|---|---|
| 1 | Basic Heat Map: Displays values in a grid format, with cell color intensity representing the magnitude of the value. |
| 2 | Large Heat Map Optimization: Efficient rendering techniques for heat maps with a large number of rows and columns. |
| 3 | Categorical Axes: Both X and Y axes typically represent categories (e.g., days of the week vs. hours of the day, products vs. regions). |
| 4 | Color Axis: A configurable color gradient (colorAxis) maps values to colors, often with a legend explaining the scale. |
| 5 | Data Labels: Option to display the actual value within each cell. |
Heat maps are commonly used in areas like web analytics (user activity), biology (gene expression), and finance (market correlations).
