asp.net - How to change chart legend alignment

Change a Chart legend’s alignment
The Chart class serves as the root class of the Chart control. The Chart class exposes all of the properties, methods, and events of the Chart Web server control. The Chart Series collection property stores Series objects which are used to store data that is to be displayed, along with attributes of that data. The Chart ChartAreas collection property stores ChartArea objects, which are primarily used to draw one or more charts using one set of axes.

The following asp.net c# web development tutorial code demonstrates how we can change a Chart legend’s alignment. Here we will use the Chart class Legends property to get the legend collection. Then we will get the specified legend instance by its id. And then we will change the Chart legend’s alignment by setting the Legend class Alignment property value.

The Chart Legends property gets or sets a LegendCollection object that is used to store all Legend objects used by the Chart control. This property value is a LegendCollection that is used to store all Legend objects. This Chart collection property stores all Legend objects used by the Chart control.

The Legend class represents the legend for the chart image. The Legend class encapsulates all the functionality of the Chart control's legend and is exposed using the Legends collection property of the root Chart object. In a Chart object can be any number of legends for a chart image.

The Legend class Alignment property gets or sets the alignment of the legend. This property value is a StringAlignment which is a .NET Framework StringAlignment enumeration value that represents the alignment of the legend. The default value is Near.

The Chart legend can be aligned so that it is Near, Center, or Far. Its alignment is also affected by the Docking property setting. But setting the Legend Alignment property will have no effect if the Position property is not set to Auto.

The StringAlignment enumeration specifies the alignment of a text string relative to its layout rectangle.
