Calendar View v4

Full Screen

This example demonstrates loading of CSV data, which is then quantized into a diverging color scale. The values are visualized as colored cells per day. Days are arranged into columns by week, then grouped by month and years. Colors by Cynthia Brewer. Layout inspired by Rick Wicklin and Robert Allison. Dow Jones historical data copyright Yahoo!
