Point visible in some values and not in others

[acastro]

Hello,

If I set points visible in a serie, it shows points in all the values of the serie.
Is it possible to show the points only in some points programming?


Thanks in advance

Hi wakeup,

You can use null points to hide those you want. Add your points with Color.Transparent or change their state with SetNull method.

Hello wakeup,

I suggest other option using GetPointerStyle that I think you could use it too, if you want. Please, see next code and check if works as you want.

Code: Select all

public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }
        private Steema.TeeChart.Styles.Line line1;
        private void InitializeChart()
        {
            line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
            line1.FillSampleValues(10);
            line1.Pointer.Visible = true;
            line1.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(line1_GetPointerStyle);
        }
        void line1_GetPointerStyle(Steema.TeeChart.Styles.CustomPoint series, Steema.TeeChart.Styles.GetPointerStyleEventArgs e)
        {
            if (e.ValueIndex < 3)
            {
                e.Style = Steema.TeeChart.Styles.PointerStyles.Nothing;
            }
            else
            {
                e.Style = Steema.TeeChart.Styles.PointerStyles.Rectangle;
            }
        }

I hope will helps.

Thanks,
