Controls the appearance of the built-in legend of a chart panel. The legend is the box in chart graphics where the points of a chart are labeled or all the charts being displayed are labeled. The Legend has properties including BoxSize, Lines, and LegendStyle. Use the Visible property to hide or show the Legend.
Usually, the legend dynamically chooses and updates the Lines property to determine what to show. By using the OnGetLegendStrings event, you can add lines to the top of the legend. By using the Fixed property, you can update the Lines and the legend will not overwrite them.

Use the stand-alone legend controls (TRSLegendListBox and TRSChartLegendBox) for more control and visual appeal than the built-in legend. |
