X axis type is DateTime
. I want to know how to extract original DateTime
value from the double value on the x axis corresponding to the point in my series?
I can add point with
point->SetValueXY(xdateTime,yvalue);
chart1->Series[0]-Add(point);
Try this C# code, it should give you a start. I use it to add text to a Label
thats shows the x value as date and the yvalue as a number. Hope this helps
public void Cht_Click(object sender, System.Windows.Forms.MouseEventArgs e)
{
//Call HitTest()
HitTestResult result = sender.HitTest(e.X, e.Y);
//If the mouse if over a data point
if (result.ChartElementType == ChartElementType.DataPoint) {
//Reset Data Point Attributes
DataPoint point = default(DataPoint);
//Find selected data point
point = result.Series.Points(result.PointIndex);
//extract x value
System.DateTime _date = System.DateTime.FromOADate(point.XValue);
Label24.Text = "Date: " + Strings.Format(_date, "dd/MM/yy") + " Value: " + point.YValues(0);
}
}
