Specifies the TRSChartPanel that the legend should display charts and/or values for. Set the Panel property if you want the legend to display a legend similar to the Legend of the TRSChartPanel. In this case, the legend will display all the chart names if there is more than one chart attached to the panel. However, if there is only one chart attached to the panel, the legend would display the chart's values. To only display one chart's values, leave the Panel property blank and set the Chart property.
