The floating toolbar for the Label element is almost the same as the Header/Footer toolbars except that it has an Edit text command for its text and different command items in its drop-down menu. Its drop-down menu has an Attached by Coordinate, Attached By Data Coordinate, and an Attached By Data Index command item. The Attached By Coordinate attaches the label anywhere on the chart. The number of pixels can be specified between the top-left corners of the chart to the ChartLabel. The Attached By Data Coordinate item attaches the label anywhere inside the PlotArea. The data coordinates can be specified. The Attached By Data Index item attaches the label to a specific data point on the chart. The series and point indices and the ChartGroup can be specified. For more information on how to use these attachment methods at design time please see Attaching and Positioning Chart Labels. If you would like to see how to use these attachment methods programmatically through code, please see Attaching the Chart Label by Pixel Coordinate, Attaching the Chart Label by Data Coordinate, Attaching the Chart Label by Data Point, or Attaching the Chart Label by Data Point and Y Value. The figure below illustrates the unique command buttons in the Label toolbar.
