Vertical
To draw a chart in a vertical manner, change the orientation of the axis using the isTransposed property, which is supported by all series types.

];Binding data with series
You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

];Empty points
Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.
Mode
Use the mode property to control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

Series render
The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.
