React PieChart - legend
The PieChart widget can include a legend. It helps you distinguish and identify the points of the displayed series. Each point is presented by an item on the legend. An item marker identifies the point's (slice's) color. An item label displays a value corresponding to the point. Use the legend property to set up PieChart legend options to the required values. To learn more about the legend and its options, refer to the Legend topic.

Use the HorizontalAlignment
enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: Left

hoverMode
In the PieChart widget, legend items represent series points. When a legend item is hovered over, the corresponding series point is highlighted. To prevent this behavior, set the hoverMode property to 'none'.
You can set a custom 'hover' style for series points. To do this, use the series.hoverStyle configuration object.

margin
Specifies the distance between the legend and surrounding widget elements or container borders in pixels.
When this option is set to a number, the specified margin applies to all the sides of the legend. Alternatively, the margin option can be set to an object. This object specifies margins for each side of the legend separately.
Whether or not the specified margin is applied to a particular side of the legend depends on the legend's location. The location is determined by the horizontalAlignment and verticalAlignment options. Refer to the top, bottom, left and right options' description to discover when the margin applies to the corresponding side of the legend.
orientation
When this option is set to 'vertical', legend items are displayed vertically (i.e., in a column). When this option is set to 'horizontal', legend items are displayed horizontally (i.e, in a row). When this option is not defined, the legend orientation is chosen automatically.
