Problem on BottomAxis ticks and labels

[PS Soluções]

Whenever I activate a VolumeSeries in my chart, the BottomAxis labels and ticks change to accomodate the series' Marks.

How do I disable that?

Hello PS Soluções,

I couldn't reproduce your problem using last version of TeeChartVCL 2010 and next code:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1.View3D:=false;
Series1.Active:=False;
Series2.FillSampleValues(10);
Series2.Marks.visible:=True;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
Series1.Active:=True;
Series2.Active:=False;
Series1.FillSampleValues();
Series1.Marks.Visible := True;
end;

Could you say us if previous code works as you want? Moreover, Can you say us which version of TeeChartVCL are you using?

Thanks,

Hi,

I'm using TeeChart Pro ActiveX v8.0.0.8 .

Plase, try sample my code. When showing only FastLineSeries, ticks behave as usual. When VolumeSeries is also Active, the evenly spaced "ticks" on bottom axis disappear, showing only ticks for the "labels" of the volume series. I don't know if this is a BUG or a feature. If it is a feature, I can't find a way to disable it.

Here's a sample code in C#.

Code: Select all

using System;
using System.Collections.Generic;

using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using TeeChart;

        {

            {

Hello PS Soluções,

If you want values of both series appears on the axes Bottom you need change labels style. You can do it using labels property style TChart1.Axis.Bottom.Labels.Styleand change default style for talValue as do next code:

Code: Select all

Private Sub Form_Load()
InitializeChart
End Sub
Private Sub InitializeChart()
TChart1.AddSeries scFastLine
TChart1.AddSeries scVolume
TChart1.Aspect.View3D = False
TeeCommander1.Chart = TChart1
'Add Fastlin series
TChart1.Series(0).FillSampleValues (10)
TChart1.Series(0).Marks.Visible = True
TChart1.Series(0).Marks.Style = smsXValue
TChart1.Series(0).Color = vbBlue
'Add Volum Series values
Dim s As Long

With TChart1.Series(1)

s = .AddXY(1, 100, "#1", vbRed)
s = .AddXY(2, 500, "#2", vbRed)
s = .AddXY(3, 248, "#3", vbRed)
.ColorEachPoint = True
.ShowInLegend = False
.VerticalAxis = aLeftAxis
.Marks.Visible = True
.Marks.MultiLine = False
.Marks.Shadow.Visible = False
End With
With TChart1.Series(1).asVolume
.UseYOrigin = True
.YOrigin = 0
.LinePen.Width = 3
End With
TChart1.Axis.Bottom.Labels.Style = talValue
End Sub

Could you say if previous code works as you want?

I hope will helps.

It works! Thanks for the help.
