How can I display labels for each point plotted in a ZedGraph chart?
Since that site is down now, here's a code snippet to give an example of how to do it:
myLine.GetRange(out other, out other, out minY, out maxY, false, false, myPane);
double Yinterval = Math.Abs(maxY - minY) / 25;
// Loop to add text labels to the points
for (int i = 0; i < tempPoints.Count; i++) {
// Get the pointpair
ZedGraph.PointPair pt = tempPoints[i];
// Create a text label from the Y data value
ZedGraph.TextObj text = new ZedGraph.TextObj(pt.Y.ToString(), pt.X, pt.Y + Yinterval,
ZedGraph.CoordType.AxisXYScale, ZedGraph.AlignH.Left, ZedGraph.AlignV.Center);
text.FontSpec.FontColor = tempHolder.Color;
text.ZOrder = ZedGraph.ZOrder.A_InFront;
// Hide the border and the fill
text.FontSpec.Border.IsVisible = false;
text.FontSpec.Fill.IsVisible = false;
text.FontSpec.Size = 10f;
text.FontSpec.Angle = 45;
string lblString = "name";
Link lblLink = new Link(lblString, "#", "");
text.Link = lblLink;
myPane.GraphObjList.Add(text);
}
For each point, create a text object with your label text, and add it to the graph.
