Heat Map Algorithm Based on Value

Question

I am looking for documentation on a heatmap algorithm. I found some implementations, but they do not calculate the gradient the way I look. Instead of calculating with hits, I want to associate data points with a value.

The only thing I found is the openheatmap.com source code . This is great stuff, but I'm looking to create gradients on the fly, not from a dataset.

I am looking to create a real-time heat map similar to the tweet world .

Exponential decay means that even very active pixels will have the final result - in other words, it is stable.
