Specifies the minimum value for the range of the axis. The    Minimum and    Maximum properties specify the full range of the axis, regardless of whether the axis is zoomed or not. The    ZoomMinimum and    ZoomMaximum properties return the zoomed range of the axis - when the axis is not zoomed, these properties equal the minimum and maximum properties.

Use the Minimum property to set the full mnimum range of the axis. Alternatively, you can include axAutomaticMinimum in the    Options property and the axis will automatically calculate the minimum value based on the chart values ( FMX.RS.ChartPanel.TRSChartValues class). Setting the Minimum property manually causes the axis to remove the axAutomaticMinimum member from the Options set.

The following code sets the Minimum and Maximum range before addings some points to a chart:

Delphi

var
   i: Integer;
 begin
   // set range from 0 to 100 and 0 to 1
   RSPointChart1.HorizontalAxis.Minimum := 0;
   RSPointChart1.HorizontalAxis.Maximum := 100;
   RSPointChart1.VerticalAxis.Minimum := 0;
   RSPointChart1.VerticalAxis.Maximum := 1;
    // now add 10 points
   for i := 0 to 9 do
     RSPointChart1.Values.Add(Random(100), Random);
 end;
