Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)
Each legend entry has two parts: the text of the entry, which is the name of the series or trendline associated with the legend entry; and the entry marker, which visually links the legend entry with its associated series or trendline in the chart. The formatting properties for the entry marker and its associated series or trendline are contained in the LegendKey object.
Use the LegendEntries method to return the LegendEntries collection.
Use LegendEntries(index), where index is the legend entry index number, to return a single LegendEntry object. You cannot return legend entries by name.
The index number represents the position of the legend entry in the legend. LegendEntries(1) is at the top of the legend; LegendEntries(LegendEntries.Count) is at the bottom.
