A tiny script to draw a sparkline graph in canvas. IE9+, Chrome & FF tested.
IE8 is supported with a polyfill. ( https://code.google.com/p/explorercanvas/downloads/list )
I've added the ability to display a colour gradient as the sparkline moves left-to-right.
Usage: <canvas class="sparkline" data-sparkline="1,2,4,7,8,8,5,3,2,1"></canvas> where data-sparkline is a comma-delimited list of values.
Enjoy! Feel free to make suggestions for improvements. I have made an angular directive version which I may add to this git repository in the future.
