Annotation String Position

I need to center the string on an annotation horizontally. If I use AnnotationChart.Shape.TextAlign = StringAlignment.Center, the string should be centered horizontally? However, I can only get it positioned in the left near position?

Hello lilo,
If you use the Annotation tool property TextAlign and choose Center option, the text is Centered in the center of the Annotation tool, if you choose near option, it is aligned to left bound of rectangle and if you choose far option, the text is aligned to right bound of rectangle. See next code to check it:
Code: Select all
Steema.TeeChart.TChart tChart1;
public Form1()
{
InitializeComponent();
tChart1 = new TChart();
this.Controls.Add(tChart1);
// tChart1.Dock = DockStyle.Fill;
tChart1.Top = 150;
tChart1.Left = 100;
tChart1.Height = 400;
tChart1.Width = 550;
tChart1.Aspect.View3D = false;
InitializeChart();
}
private void InitializeChart()
{
Steema.TeeChart.Styles.Bar bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
Steema.TeeChart.Tools.Annotation an = new Steema.TeeChart.Tools.Annotation(tChart1.Chart);
bar1.FillSampleValues();
an.Text = " Steema Software";
an.TextAlign = StringAlignment.Center;
button1.Click += button1_Click;
checkBox1.Checked = true;
checkBox2.Checked = false;
checkBox3.Checked = false;
checkBox1.CheckedChanged += checkBox1_CheckedChanged;
checkBox2.CheckedChanged += checkBox2_CheckedChanged;
checkBox3.CheckedChanged += checkBox3_CheckedChanged;
}
void checkBox3_CheckedChanged(object sender, EventArgs e)
{
Steema.TeeChart.Tools.Annotation tool = (tChart1.Tools[0] as Steema.TeeChart.Tools.Annotation);
if (checkBox3.Checked)
{
tool.TextAlign = StringAlignment.Far;
checkBox1.Checked = false;
checkBox2.Checked = false;
}
}
void checkBox2_CheckedChanged(object sender, EventArgs e)
{
Steema.TeeChart.Tools.Annotation tool = (tChart1.Tools[0] as Steema.TeeChart.Tools.Annotation);
if (checkBox2.Checked)
{
tool.TextAlign = StringAlignment.Near;
}
checkBox1.Checked = false;
checkBox3.Checked = false;
}
void checkBox1_CheckedChanged(object sender, EventArgs e)
{
Steema.TeeChart.Tools.Annotation tool = (tChart1.Tools[0] as Steema.TeeChart.Tools.Annotation);
if (checkBox1.Checked)
{
tool.TextAlign = StringAlignment.Center;
}
checkBox2.Checked = false;
checkBox3.Checked = false;
}
void button1_Click(object sender, EventArgs e)
{
tChart1.ShowEditor();
}
Please, could you check my code and tell us if it works in your end? If you consider it doesn't work properly for you, could you please tell us why?
Thanks,

Hi Sandra,
I struck another problem, the centering works fine for a text string with two characters or more, but does not work with one character. How can I center one character?

Hello lilo,
I have changed the Annotation Tools string
Steema Software to
A and it is centered correctly, you can check it in my attached project. If in my project your problem doesn't occurs, but in your project the problem appears, could you please send us your project and tell us which version are you using, because can suggest you a good solution?
Thanks,

Thanks Sandra,
I can't open your project, as I am still using Visual Studio 2010...I might have to download an express version. In the meantime, I am able to workaround the problem by setting the annotation width and height manually to the character width and height.

Hello lilo,
I have modified my project, because you can use it in VS2010. Could you test my attached project?
Thanks,

Hi Sandra,
Thanks, your project works fine. My project(s) will not work. I am using Visual Basic Net 2010 TeeChart V 4.1.2012.1312.
I am creating the annotation tools at runtime without the edit window.
Private Sub TChart1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TChart1.MouseDown
NumText = NumText + 1
ReDim Preserve AnnotationChart(NumText)
AnnotationChart(NumText) = New Steema.TeeChart.Tools.RectangleTool(TChart1.Chart)
AnnotationChart(NumText).PositionUnits = Steema.TeeChart.PositionUnits.Pixels
AnnotationChart(NumText).Shape.TextAlign = StringAlignment.Center
AnnotationChart(NumText).AllowResize = True
AnnotationChart(NumText).AllowEdit = True
AnnotationChart(NumText).AllowDrag = True
AnnotationChart(NumText).AutoSize = True
AnnotationChart(NumText).ClipText = True
AnnotationChart(NumText).Shape.Transparent = True
AnnotationChart(NumText).Shape.Font.Color = FontColor
AnnotationChart(NumText).Shape.Font.Name = NewTextFont
AnnotationChart(NumText).Shape.Font.Size = NewTextSize
AnnotationChart(NumText).Shape.Font.Bold = NewTextBold
AnnotationChart(NumText).Shape.Font.Italic = NewTextItalic
AnnotationChart(NumText).Shape.Font.Underline = NewTextUnderline
AnnotationChart(NumText).Shape.CustomPosition = True
AnnotationChart(NumText).Text = SymbolType
AnnotationChart(NumText).EndEdit()
AnnotationChart(NumText).Left = e.X - (AnnotationChart(NumText).Width / 2)
AnnotationChart(NumText).Top = e.Y - (AnnotationChart(NumText).Bounds.Height / 2)
AnnotationChart(NumText).Shape.Visible = True

Hello lilo,
I have found your problem. It seems appears when you access to the RectangleTool TextAlign property, using the Shape of this tool as do in next line of code:
Code: Select all
AnnotationChart(NumText).Shape.TextAlign = StringAlignment.Center
In this point, you must know you can access to RectangleTool TextAlign property directly, without using shape. I have changed it in your code and the problem of align disappears. You can see the modification, in next lines of code:
Code: Select all
Private Sub TChart1_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles TChart1.MouseDown
NumText = NumText + 1
ReDim Preserve AnnotationChart(NumText)
AnnotationChart(NumText) = New Steema.TeeChart.Tools.RectangleTool(TChart1.Chart)
AnnotationChart(NumText).PositionUnits = Steema.TeeChart.PositionUnits.Pixels
AnnotationChart(NumText).TextAlign = StringAlignment.Center
AnnotationChart(NumText).AllowResize = True
AnnotationChart(NumText).AllowEdit = True
AnnotationChart(NumText).AllowDrag = True
AnnotationChart(NumText).AutoSize = True
AnnotationChart(NumText).ClipText = True
'Change Shape.
AnnotationChart(NumText).Shape.Visible = True
AnnotationChart(NumText).Shape.Pen.Visible = True
AnnotationChart(NumText).Shape.Transparent = False 'True
AnnotationChart(NumText).Shape.Font.Color = Color.Black
AnnotationChart(NumText).Shape.Font.Name = "Arial" 'NewTextFont
AnnotationChart(NumText).Shape.Font.Size = 26 'NewTextSize
AnnotationChart(NumText).Shape.Font.Bold = False 'NewTextBold
AnnotationChart(NumText).Shape.Font.Italic = False 'NewTextItalic
AnnotationChart(NumText).Shape.Font.Underline = False 'NewTextUnderline
AnnotationChart(NumText).Shape.CustomPosition = True
AnnotationChart(NumText).Text = "+"
AnnotationChart(NumText).EndEdit()
AnnotationChart(NumText).Left = e.X - (AnnotationChart(NumText).Width / 2)
AnnotationChart(NumText).Top = e.Y - (AnnotationChart(NumText).Bounds.Height / 2)
End Sub
Could you tell us if previous code solve your problem?
I hope will helps.
Thanks,
