CKSparkline is an open source library that provides your application easy access to Sparkline Graphs. Sparklines are well suited to visualizing information in the screen resolution available to the iPhone and iPod Touch. Use CKSparkline in conjunction with a table view to present vast amounts of information in a small space.
Provide CKSparkline with your dataset and away you go. Optionally customize background and line colours to tailor CKSparkline to fit your own application's look and feel.
