Hello Sir,
I want to display the nearest Axis values of X,Y,Z on right clicking at a particular point of surface,in a small dialog.
How can i get these values using Steema Chart.
I have uploaded image "3D Plot.JPG" , which shows an arrow highlighting the desired value.
Please help.Thanks in Advance.
Regards,
Sanyog

Hi Sanyog,
Here there is an example of how I think you could do this:
Code: Select all
public Form1()
{
InitializeComponent();
InitializeChart();
}
Steema.TeeChart.Styles.Surface surf1;
Steema.TeeChart.Tools.Annotation annotation1;
private void InitializeChart()
{
tChart1.Aspect.Chart3DPercent = 50;
chartController1.Chart = tChart1;
annotation1 = new Steema.TeeChart.Tools.Annotation(tChart1.Chart);
annotation1.Active = false;
surf1 = new Steema.TeeChart.Styles.Surface(tChart1.Chart);
surf1.FillSampleValues(25);
surf1.Click += new MouseEventHandler(surf1_Click);
}
void surf1_Click(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
int ValueIndex = ((Steema.TeeChart.Styles.Surface)sender).Clicked(e.X, e.Y);
if (ValueIndex > -1)
{
annotation1.Left = e.X;
annotation1.Top = e.Y;
annotation1.Text = "X: " + surf1.XValues.Value[ValueIndex].ToString() + " Y: " + surf1.YValues.Value[ValueIndex].ToString() + " Z: " + surf1.ZValues.Value[ValueIndex].ToString();
annotation1.Active = true;
}
}
else
{
annotation1.Active = false;
}
