Contains the collection of points that make up a line chart. Each FMX.RS.Charts.TRS2DChartValue item in the collection defines one point (X and Y). The line chart connects the points using the LineStyle. Use the Values collection to add, delete, and modify points in the chart.

Property Value
Type: TRS2DChartValues
The following code sets the line style connecting chart points and then adds 2 chart points:
Delphi
|
var
Value: TRS2DChartValue; // note, this type should be the same that the chart uses (e.g., TRS2DChartValue, TRSArrowChartValue, etc)
begin
RSLineChart1.LineStyle := lsStairStep;
RSLineChart1.Enabled := [bcLine];
// Add first point
Value := RSLineChart1.Values.Add;
Value.Color := clRed;
Value.X := 10.0;
Value.Y := 15.0;
// Add second point
Value := MyChart.Values.Add;
Value.Color := clRed;
Value.X := 20.0;
Value.Y := 15.0; // y value is the same so this will be a horizontal line segment
end;
