Hello MiketheLad,


I suggest you define the position of your values when you add it in the series, as do in next example of code:

Code: Select all

        Steema.TeeChart.Styles.Pie Series1;
        private void InitializeChart()
        {

            Series1 = new Steema.TeeChart.Styles.Pie(tChart1.Chart);
            Series1.Add(74);
            Series1.Add(6);
            Series1.Add(5);
            Series1.Add(8);
            Series1.Add(4);
            Series1.Marks.Style = Steema.TeeChart.Styles.MarksStyles.Percent;
   
        }
Can you tell us if previous code helps you to solve your problem?

Thanks,

I have treid changing the order, but seem unable to get the white to be at the top, also what about the box and font size of the labels next to the pie




Steema.TeeChart.TChart tChart2 = new Steema.TeeChart.TChart();
Steema.TeeChart.Styles.Pie pie = new Steema.TeeChart.Styles.Pie(tChart2.Chart);
tChart2.Legend.Visible = false;
tChart2.Header.Text = "";
tChart2.Chart.Panel.Color = System.Drawing.Color.White;
tChart2.Chart.Panel.Visible = false;
tChart2.Chart.Walls.Visible = false;
tChart2.Chart.Panel.Bevel.Outer = Steema.TeeChart.Drawing.BevelStyles.None;
tChart2.Chart.Panel.Bevel.Inner = Steema.TeeChart.Drawing.BevelStyles.None;
tChart2.Aspect.View3D = false;

pie.Add(Convert.ToInt32(ethnicperc1), ethnicperc1 + "%", Color.FromArgb(49, 151, 101));
pie.Add(Convert.ToInt32(ethnicperc3), ethnicperc3 + "%", Color.FromArgb(245, 152, 31));
pie.Add(Convert.ToInt32(ethnicperc4), ethnicperc4 + "%", Color.FromArgb(205, 205, 205));
pie.Add(Convert.ToInt32(ethnicperc5), ethnicperc5 + "%", Color.FromArgb(244, 243, 160));
pie.Add(Convert.ToInt32(ethnicperc6), ethnicperc6 + "%", Color.FromArgb(157, 197, 233));
pie.Add(Convert.ToInt32(ethnicperc2), ethnicperc2 + "%", Color.FromArgb(255, 255, 255));

Hello MikeTheLad,

Using last version of TeeChart2011 and next code:

Code: Select all

        private void InitializeChart()
        {
           Steema.TeeChart.Styles.Pie pie = new Steema.TeeChart.Styles.Pie(tChart1.Chart);
           tChart1.Legend.Visible = false;
           tChart1.Header.Text = "";
           pie.Circled = true;
           tChart1.Chart.Panel.Color = System.Drawing.Color.White;
           tChart1.Chart.Panel.Bevel.Outer = Steema.TeeChart.Drawing.BevelStyles.None;
           tChart1.Chart.Panel.Bevel.Inner = Steema.TeeChart.Drawing.BevelStyles.None;

           tChart1.Aspect.View3D = false;
           Random rnd = new Random();
           int ethnicperc1, ethnicperc2, ethnicperc3,ethnicperc4, ethnicperc5, ethnicperc6;
           ethnicperc1 = 74;
           ethnicperc2 = 4;
           ethnicperc3 = 6;
           ethnicperc4 = 2;
           ethnicperc5 = 5;
           ethnicperc6 = 8;
           pie.Add(ethnicperc1, ethnicperc1.ToString() + "%", Color.FromArgb(49, 151, 101));
           pie.Add(ethnicperc3, ethnicperc3.ToString() + "%", Color.FromArgb(245, 152, 31));
           pie.Add(ethnicperc4, ethnicperc4.ToString() + "%", Color.FromArgb(205, 205, 205));
           pie.Add(ethnicperc5, ethnicperc5.ToString() + "%", Color.FromArgb(244, 243, 160));
           pie.Add(ethnicperc6, ethnicperc6.ToString() + "%", Color.FromArgb(157, 197, 233));
           pie.Add(ethnicperc2, ethnicperc2.ToString() + "%", Color.FromArgb(255, 255, 255));
}
I have gotten next results:

Can you try again run previous code and tell us if you can get a good results? On the other hand, If you doesn't use last version of TeeChartFor.Net, please tell us which version are you using now.
On the numbers around the graph, require no box and the font to bigger
Sorry I forgot answer this question. If you want as the boxs of Marks don't appear and font of Marks is to bigger, you need use next properties of Marks to modify their aspect:
  • - Series.Marks.Pen.Visible = False or True;
    - Series.Marks.Color.Transparency= 100. You have indicate the % of transparency you want to marks. And also you can use Series.Marks.Transparent = true; where you indicate as if you want Mark transparent or not.
    - Series.Marks.Font.Size = 12. To Change the size of font.
I have added some of previous properties in your code:

Code: Select all

          ....
           //Marks;
           pie.Marks.Transparent = true;
           pie.Marks.Transparency = 100;
           pie.Marks.Pen.Visible = false;
           pie.Marks.Arrow.Visible = false;
           pie.Marks.Font.Size = 12;
And I have gotten next results:

Can you tell us, if previous lines of code works as you expected?

Hello MikeTheLad,

Series have a method that allow rotate the Series. To achieve as you want I recommend rotate your Series an angle of 180º as do in next line of code:

Code: Select all

 pie.Rotate(180);
Can you tell us, if previous line works as you expected?

Thanks,
