Angular Charts - Bar Sparklines

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