本文介绍了ZedGraph标签的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在ZedGraph中,如何显示每个点和 XAxis
中的文本标签?
In ZedGraph, how do I show text labels for each point and in the XAxis
all together?
如果我这样做
myPane.XAxis.Type = AxisType.Text;
myPane.XAxis.Scale.TextLabels = array_of_string;
我在XAxis上得到这样的标签
I get labels on the XAxis like this
如果我do
for (int i = 0; i < myCurve.Points.Count; i++)
{
PointPair pt = myCurve.Points[i];
// Create a text label from the Y data value
TextObj text = new TextObj(
pt.Y.ToString("f0"), pt.X, pt.Y + 0.1,
CoordType.AxisXYScale, AlignH.Left, AlignV.Center);
text.ZOrder = ZOrder.A_InFront;
text.FontSpec.Angle = 0;
myPane.GraphObjList.Add(text);
}
我在曲线上得到标签,如下
I get labels on the curve, like this
但是如果我同时做这两个,曲线上的标签消失。
But if I do both at the same time, labels on the curve disappear.
有没有办法组合这两种标签?
Is there a way to combine both kind of labels?
推荐答案
在您澄清问题后,我已经更改了我的答案。
您只需要记住正确定位标签:
I've changed my answer after you clarified the question. You just have to remember to position the labels correctly:
<%
System.Collections.Generic.List<ZedGraphWebPointPair> points = new System.Collections.Generic.List<ZedGraphWebPointPair>();
for (int i = 0; i < 15; i++)
{
// Let's have some fun with maths
points.Add(new ZedGraphWebPointPair
{
X = i,
Y = Math.Pow(i - 10, 2) * -1 + 120
});
}
System.Collections.Generic.List<string> XAxisLabels = new System.Collections.Generic.List<string>();
TestGraph.CurveList.Add(new ZedGraphWebLineItem { Color = System.Drawing.Color.Red });
TestGraph.XAxis.Scale.FontSpec.Size = 9;
int j = 1;
foreach (ZedGraphWebPointPair point in points)
{
// Add the points we calculated
TestGraph.CurveList[0].Points.Add(point);
// Add the labels for the points
TestGraph.GraphObjList.Add(new ZedGraphWebTextObj
{
Location =
{
CoordinateFrame = ZedGraph.CoordType.XChartFractionYScale,
// Make sure we position them according to the CoordinateFrame
X = Convert.ToSingle(j) / points.Count - 0.05f,
Y = Convert.ToSingle(point.Y) + 3f,
AlignV = ZedGraph.AlignV.Top
},
Text = point.Y.ToString(),
FontSpec = { Angle = 90, Size = 9, Border = { IsVisible = false } }
});
// Add the labels for the XAxis
XAxisLabels.Add(String.Format("P{0}", j));
j++;
}
TestGraph.RenderGraph += delegate(ZedGraphWeb zgw, System.Drawing.Graphics g, ZedGraph.MasterPane mp)
{
ZedGraph.GraphPane gp = mp[0];
gp.XAxis.Type = ZedGraph.AxisType.Text;
gp.XAxis.Scale.TextLabels = XAxisLabels.ToArray();
};
%>
该代码将生成此图形:
