Timeplot is a DHTML-based AJAXy widget for plotting time series and overlay time-based events over them (with the same data formats that Timeline supports). Here is a live example:
New Legal Permanent Residents in the U.S. (per year) vs. U.S. Population vs. U.S. History

More Live Examples

  • Energy Prices in the U.S. since 1975: this timeplot shows how the cost of gasoline in the US is strongly correlated with oil import from foreign countries, while the cost of electricity is not as strongly correlated.
  • Housing vs. Stock Market in the U.S. since 1975: this timeplot shows the trends of growth for two of the biggest investment sectors in the U.S., housing and the stock market, in relationship with monetary inflation.
  • Immigration in the U.S. since 1820: this timeplot shows the amount of people that legally obtained permanent residency in the U.S. over almost 200 years.
  • George W. Bush Approval Ratings: this timeplot shows the sampled approval ratings of George W. Bush's job as president of the U.S. over his 2 terms until until today.
  • SIMILE Project Statistics: this series of timeplots shows the statistics of the SIMILE project collected by analyzing web server and mail server logs. This example shows how Timeplot is able to post-process the data to plot things like differences between two columns or the moving average of a time series on the fly.
