Note

Now I use Google Docs to record the number, see this doc. It’s easier to add a data point, the only problem is it’s too ugly. (2010-06-03)

The chart below is the weekly users of Keep Last Two Tabs, a Chrome Extension of mine. This extension does what it claims, it’s silly and amazingly to see the number of users is actually growing up.

A week ago, I stumbled upon Flot, a pure JavaScript plotting library for jQuery. It produces nice and pretty chart comparing to Google Visualization API’s Annotated Time Line, a Flash based. Here is a post about how I used it.

I feel Annotated Time Line is more easier (or less customizable) to use because you don’t need some functions, but Flot is more comprehensive library (and it’s Open Source), you can have more types of chart and make the chart do whatever you want if you know JavaScript.
