Sparkline Charts

Bar Sparklines

Documentation

This demo illustrates the sparklines of the bar type. A number of options for each sparkline is changed. Most of these options define the appearance of specific sparkline elements. Note that in this demo, the Sparkline widget obtains data using the DataSource object. You can change filtering conditions for the data using the drop-down menu under the table.
