[lilo]

How to set the points style property in code?

To change points from square, circle etc...

[lilo]

for ternay plot

OK, I have the solution.

Use pointer.style

Hi,

After checking, this does not seem to do what i need. How can I change the ppoints style in code, without the editor?

[lilo]

This changes all the points. Is it possible to change the style of individual points?

Hello lilo,

Could you please, check next lines of code works as you want:

Code: Select all

  private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            Steema.TeeChart.Styles.Ternary series1 = new Steema.TeeChart.Styles.Ternary(tChart1.Chart);
            series1.FillSampleValues();
            series1.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Circle;
           
        }

I hope will helps.

Thanks,

That seems to be a random point generator. It fills the chart with a random set of points, but they are all circles. I am trying to specify a different shape for each data point. The data points are not randomly generated. they are read from input file.

I use this code:
For i= 1 to TotalPoints
Ternary1.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Circle
Ternary1.Add(X(i), Y(i), ZA(i), SymbWeight(i), Color(i))
Next TotalPoints

But all the points on the plot change to circles.

[lilo]

I use this code:
For i= 1 to TotalPoints
If symbol(i)=1 Then Ternary1.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Circle
If symbol(i)=2 Then Ternary1.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Cross
Ternary1.Add(X(i), Y(i), ZA(i), SymbWeight(i), Color(i))
Next TotalPoints

OK, I have the solution. Use a series of ternary plots, assigning each series a different symbol.

Hello lilo,

I am glad that you have found a solution . On the other hand, I have made for you a simple code using GetStylePoint event for change style of each pointer:

Code: Select all

private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            Steema.TeeChart.Styles.Ternary series1 = new Steema.TeeChart.Styles.Ternary(tChart1.Chart);
            series1.FillSampleValues();
            series1.GetPointerStyle += new Steema.TeeChart.Styles.Ternary.GetPointerStyleEventHandler(series1_GetPointerStyle);
        }

        void series1_GetPointerStyle(Steema.TeeChart.Styles.Ternary series, Steema.TeeChart.Styles.GetPointerStyleEventArgs e)
        {
            if (series[e.ValueIndex].X > 80)
            {
                e.Style = Steema.TeeChart.Styles.PointerStyles.Circle;
            }
            else
            {
                e.Style = Steema.TeeChart.Styles.PointerStyles.Rectangle;
            }
        }

Also you can find more examples as you have done for use this events in this threads:

I hope will helps.

This may be a silly question...how is the GetPointerStyle(ByVal series As Steema.TeeChart.Styles.Ternary, ByVal e As Steema.TeeChart.Styles.GetPointerStyleEventArgs) triggered?

is it called directly?

[Narcís]

Hi lilo,

No, this is an event that is automatically fired by TeeChart when series pointers are painted. Have you seen its runtime assignment at Sandra's example?

[lilo]

Thanks, its now working

[lilo]

I can only get it working for symbols with solid color fill. Does not work with other symbols
