I'm trying to get a single cursor working with multiple series (with Datetime x-axis) on a recent teechart.net version (2.0.2546.16099) and it seems that it is not working. It seems that the problem I'm having is same as that in the topic "Cursortool tied to multiple series" i.e. problem with the XValues.IndexOf not working with DateTime. And I do not want to implement the CPU-intensive solution suggested in that topic. Is there some way around this problem? My test code is attached:
Code: Select all
private void button2_Click(object sender, EventArgs e)
{
tChart1.Aspect.View3D = false;
DateTime[] a = new DateTime[400];
double[] b = new double[400];
DateTime[] c = new DateTime[200];
double[] d = new double[200];
Random r = new Random();
for (int i = 0; i < 400; i++)
{
a[i] = new DateTime(1, 1, 1, 5, 5, 0) + new TimeSpan(0, 0, i);
b[i] = r.NextDouble() * 10;
}
for (int j = 0; j < 200; j++)
{
c[j] = new DateTime(1, 1, 1, 5, 5, 0) + new TimeSpan(0, 0, j + 200);
d[j] = r.NextDouble() * 10;
}
fastLine1.Clear();
fastLine1.Add(a, b);
fastLine2.Clear();
fastLine2.Add(c, d);
cursorTool1.XValue = (new DateTime(1, 1, 1, 5, 5, 0)).ToOADate();
}
private void cursorTool1_Change(object sender, Steema.TeeChart.Tools.CursorChangeEventArgs e)
{
int i = fastLine1.XValues.IndexOf(e.XValue);
if (i >= 0)
label5.Text = fastLine1.YValues[i].ToString();
i = fastLine2.XValues.IndexOf(e.XValue);
if (i >= 0)
label6.Text = fastLine2.YValues[i].ToString();
}
