Example: The following tiny program resizes the data container, fills it with normally distributed random numbers and shows a histogram of the data in plot window 1: 

program PlotData;

var
  Plt1 : TFrmPlots;

begin
DStore.Resize (10,40);
Dstore.FillRandomNormal (0,0,0,0,3,1.3);  // create data
if CreatePlot (1, Plt1) > 0 then
  begin
  Plt1.WindowState := wsNormal;           // make the plot visible
  Plt1.ShowHistogram (hrAll, 0,0,0,0,0, true, 'Histogram of all data');
  Plt1.PlotParams.SetDefaultColors;
  Plt1.PlotParams.ColorFill := clRed;     // adjust the colors
  Plt1.PlotParams.ColorBGnd := $EEFFDD;
  Plt1.Refresh;
  end;
end.
