Bottom Axis highlighting wrong hover over values

[Ando]

We've noticed that on all of our charts, when you hover the mouse over the bottom axis the incorrect value is highlighted. It always highlights the value to the left of the one you are hovering over.

As you can see from photo above the mouse is hovering over 08/04/2015 but 18/03/2015 is highlighted. There are hidden axis labels in here as they consecutive weeks in the data set but the wrong label is highlighted irrespective of how many labels are highlighted.

Hello Ando,

Using the code below and the latest Teechart Pro VCL/FMX v2017.21 the problem you're experiencing isn't occurs for us:

Code: Select all

Uses Series,TeeConst;
var Series1:TLineSeries;
procedure TForm3.FormCreate(Sender: TObject);
var t:Integer;
begin
        Series1 := TLineSeries.Create(Self);
        Chart1.AddSeries(Series1);
        Chart1.Title.Text.Text :=  TeeMsg_Version ;
Series1.XValues.DateTime := true;
       for t := 1 To 25 do
        Series1.AddXY(EncodeDate(2016, 4, t), Random(t));

       Chart1.Axes.Bottom.LabelsAngle := 90;

end;

Are you using latest Teechart Pro VCL/FMX version?

Thanks in advance,

[Ando]

This is what happens on my machine with the attached code

I copied your code and used that and now I get it the other way where the period to the right of the label I hover over is selected. I'm using the latest version and I'm using Delphi 10.1 Berlin Enterprise
