Sparkline

A sparkline is an unlabelled line chart that is typically drawn without axes or coordinates. Unlike a regular chart, a sparkline is not intended to give a lot of information. It is used for depicting the trend or shape of the data in a compact format for the greatest impact. For example, the stock market trends are usually shown as a sparkline. Sparklines are typically small charts embedded in spreadsheets.
