自定义ZedGraph的LineItem的符号类型 [英] Customize symbol type of a ZedGraph LineItem

问题描述

我绘制这样一个图<​​/ P>

I plot a graph like this

LineItem lineItem = new LineItem("label", pointList, Color.Black, SymbolType.Triangle);
lineItem.Line.IsVisible = _graphLineVisible;
zgc.GraphPane.CurveList.Add(lineItem);

我注意到，SymbolType有称为枚举元素用户定义，是有办法使用这个怎么样？

I notice that SymbolType have an enum element called UserDefined, is there a way to use this and how?

在理想情况下我会希望能够实现自己的符号，并用它来绘制的LineItem，这是可能的，我怎么会去这样做？

Ideally I would want to be able to implement my own Symbol and use it to draw a LineItem, is this possible and how could I go on about doing this?

推荐答案

下面是如何使用previously公布答案创建自定义箭头向下的符号，行了详细的说明：

Here is a detailed illustration of how to create custom arrow-down symbols, in line with the previously published answer:

var curve = zgc.GraphPane.AddCurve(null, new[] { 2.1, 2.6, 2.8 }, new[] { 1.8, 1.3, 1.1 }, Color.Blue);

curve.Symbol = new Symbol(SymbolType.UserDefined, Color.Red);
curve.Symbol.UserSymbol = new GraphicsPath(
    new[]
        {
            new PointF(-0.6f, -0.6f), new PointF(-0.6f, 0.6f), new PointF(-1.0f, 0.6f), new PointF(0f, 1.6f), 
            new PointF(1.0f, 0.6f), new PointF(0.6f, 0.6f), new PointF(0.6f, -0.6f),
            new PointF(-0.6f, -0.6f)
        },
    new[]
        {
            (byte)PathPointType.Start, (byte)PathPointType.Line, (byte)PathPointType.Line,
            (byte)PathPointType.Line, (byte)PathPointType.Line, (byte)PathPointType.Line,
            (byte)PathPointType.Line, (byte)PathPointType.Line
        });

运行此code会产生以下的输出：

Running this code would yield the following output:
