Sparklines are small charts, typically drawn without axes or axes labels. They display the changes’ trends in general; usually those changes are in temperature, rates or prices, in a simple and compressed form. They can be embedded in text or grouped together in a table. Whereas the typical charts are supposed to show as much as possible, sparklines are designed to show as less as possible without loss of information content.
This Sparkline Line chart shows exchange rates changed over a period of time from January 1994 till April 2006 in different countries. Actually, there are a lot of different sparkline charts organized in one table, so it looks as one big chart. All sparklines in the table are of line series type and have the same number of points. The most important points (min and max) are marked. Nothing is hovered or selected: those options are not quite necessary for sparklines.
