    In This Topic

    Xuni FlexPie provides the option to display legend for denoting the type of the data presented  in the pie slices. The position of legend is by default set to "Auto", which means the legend positions itself automatically depending on the real estate available on the device. This allows the pie to efficiently occupy the available space on the device.   

    Users have the option to customize the appearance of the legend to enhance the visual appeal of the FlexPie control. To customize the legend, you can set the following properties at design time.

    Property Description
    LegendPosition

    This property accepts the following values from the ChartPositionType enumeration:

    • Auto - This is the default value that enables responsive positioning of the legend by setting it in the best possible way depending upon the space available on the plot area. 
    • Bottom - Positions the legend at the bottom of the pie in the plot area.
    • Left - Positions the legend to the left of the pie in the plot area.
    • Right - Positions the legend to the right of the pie in the plot area.
    • Top - Positions the legend to the top of the pie in the plot area.
    • None - hides the legend.
    LegendStyle Sets the different styles of the legend.
    LegendItemStyle Sets the item style of the legend.

    The image below shows how the FlexPie appears after these properties have been set.
