A sparkline is a tiny chart that provides a simple overview of data. Use sparklines to show trends in a series of values, such as seasonal increases or decreases, economic cycles, or to highlight maximum and minimum values.
How do I create a sparkline?
Resize the chart to make it smaller. That's all
Anythng else I should know?
Sparklines can only show a single data series. If you have more than one series (column) then we only show the first.
