Description yeray alonso 2023-02-20 07:27:42 EST 
In the following example, the left axis shows labels from -0.8 to 0.8.
However, the bottom axis shows a single label at 0.
The customer expected both axes to show a similar set of labels.

uses Chart, TeeGDIPlus, TeEngine, Series;

procedure TForm1.FormCreate(Sender: TObject);
var Chart1: TChart;
begin
  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Self;
  Chart1.View3D:=False;

  Chart1.AddSeries(TLineSeries);

  Chart1.Axes.Left.SetMinMax(-0.855,0.855);
  Chart1.Axes.Bottom.SetMinMax(-0.855,0.855);
end;

Just added an extra check for XValues (with HasNoMandatoryValues method to support horizontal series), in commit 89c7b79.
