Bind to Data
In this demo, series is bound to data directly. See the Bind Series to Data article for information. The "state" field name is assigned to the argumentField property of the commonSeriesSettings object since the stacked bar chart contains series with the same argument field.
Specify Common Series Settings
To configure settings for all series in the chart, use the commonSeriesSettings object. For example, specify the series type.
Customize Stacked Bar Chart
Use the verticalAlignment and horizontalAlignment properties of the legend object to specify the legend position in the chart. You can specify the text's position relative to the marker in a legend item in the itemTextPosition property.
To configure tooltips in the chart, use the tooltip object. To enable the tooltips, assign true to the enabled property of this object. If you want to customize a specific tooltip, assign a function to the customizeTooltip property. In this demo, the function returns the tooltip's text that shows the series name and point value.
