How to update heatmap TTMSFNCMapsWeightedCoordinates?

[Shen_Jige]

I have created a heatmap and I would like to update the point coordinates and point weights. Is it a way to do that without re-creating the heatmap?
Thanks!

Yes, after updating the heatmap set Recreate to True and use BeginUpdate and Endupdate calls on the map.

procedure TForm1.Button1Click(Sender: TObject);
var
  hm: TTMSFNCMapsHeatMap;
  I: Integer;
begin
  hm := TMSFNCGoogleMaps1.HeatMaps[0];
  TMSFNCGoogleMaps1.BeginUpdate;
  for I := 0 to hm.WeightedCoordinates.Count - 1 do
  begin
    hm.WeightedCoordinates[I].Coordinate.Latitude := hm.WeightedCoordinates[I].Coordinate.Latitude + 1;
    hm.WeightedCoordinates[I].Coordinate.Longitude := hm.WeightedCoordinates[I].Coordinate.Longitude - 1;
  end;
  hm.Recreate := True;
  TMSFNCGoogleMaps1.EndUpdate;
end;

That works! Thanks!
