Heatmaps for node.js and the browser, groovy!
var heatmap = ;var heat = ;for var i = 0; i < 5000; i++var rho = Math * 2 * MathPI;var z = Math * 200;var x = 250 + Math * z;var y = 250 + Math * z;heat;heat;var fs = ;fs;
var heatmap = require('heatmap');
Create a new heatmap from an existing canvas element, a numeric width and height, or an option object with canvas or width and height fields.
Optionally, you can set the
opts.threshold to control the
rendering a little.
Add a point to the heatmap with a
params can have:
Scale the canvas by the coefficients
y is undefined, scale both x and y by the first parameter,
Render all the points onto the canvas element.
The HTML Canvas element.
Protip: with the canvas module for
node you can
heat.canvas.buffer() to get a Buffer with a PNG file all up in it.
With npm, just do:
npm install heatmap2
