AxisBehind and inverted axes

Post by Toreba » Tue Feb 12, 2019 12:59 pm

Hi,

Is there a setting somewhere that allows the axes to be drawn over the series lines, but the grid lines to remain under the series?

Regards

Toreba

Hello,

You could set the axes to be drawn on top setting DrawBehind to False. Then, you could Hide the Grids and manually draw them at OnBeforeDrawSeries event. Ie:

Code: Select all

uses Series;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=False;
  Chart1.Legend.Hide;

  Chart1.Axes.Behind:=False;
  Chart1.Axes.Left.PositionPercent:=50;
  Chart1.Axes.Left.Grid.Hide;
  Chart1.Axes.Bottom.PositionPercent:=50;
  Chart1.Axes.Bottom.Grid.Hide;

  Chart1.AddSeries(TBarSeries).FillSampleValues(3);

  Chart1.Draw;
end;

type TChartAxisAccess = class(TChartAxis);

procedure TForm1.Chart1BeforeDrawSeries(Sender: TObject);
begin
  Chart1.Axes.Left.Grid.Show;
  TChartAxisAccess(Chart1.Axes.Left).DrawGrids(Chart1.Axes.Left.Items.Count);
  Chart1.Axes.Left.Grid.Hide;

  Chart1.Axes.Bottom.Grid.Show;
  TChartAxisAccess(Chart1.Axes.Bottom).DrawGrids(Chart1.Axes.Bottom.Items.Count);
  Chart1.Axes.Bottom.Grid.Hide;
end;
