HeatMap, an open source data visualization component for Adobe Flex

A heatmap represents data on a two-dimensional plane using color. Examples in common usage include weather precipitation maps, mouse click and eye tracking on websites, and visualizations used by doctors in the medical field.

• Technology: Adobe Flex 3 "Halo"

Features

• Horizontal and vertical position values can be generated from the items in the data provider using fields or functions (similar to how Flex's List control uses labelField and labelFunction).
• Each item may be weighted to allow more complex calculations. Additionally, this feature may be used to combine items for increased performance when working with very large data sets.
• Colors and ratios may be customized as styles, and the default colorFunction may be replaced to use a different algorithm, if needed.

Examples

• Click Tracker (source) - Click multiple on the controls in the panel to see a heatmap created in real time.
• Sine + Cosine Data (source) - A programmatically-generated heatmap using weight values.
