我正在使用 ZedGraph
http://www.codeproject.com/Articles/5431/A-flexible-charting-library-for-NET?fid=26087&fr=11#xx0xx
我想绘制垂直条，然后在整个绘图区域上画一条水平线。
它似乎只到了酒吧的尽头！
我尝试添加一些 x 轴和 y 轴的值来达到这个效果，但它不起作用。
是否可以？
这是我的代码：
private void CreateGraph( ZedGraphControl zgc )
{
// get a reference to the GraphPane
GraphPane myPane = zg1.GraphPane;
// Set the Titles
myPane.Title.Text = "My Test Bar Graph";
myPane.XAxis.Title.Text = "Label";
myPane.YAxis.Title.Text = "My Y Axis";
// Make up some random data points
string[] labels = { "Panther", "Lion" };
double[] y = { 100, 115 };
double[] x = {0, 900 };
double[] y4 = { 90, 90};
// Generate a black line with "Curve 4" in the legend
LineItem myCurve = myPane.AddCurve("Curve 4", x, y4, Color.Black, SymbolType.Circle);
// Generate a red bar with "Curve 1" in the legend
BarItem myBar = myPane.AddBar("Curve 1", null, y, Color.Red);
myBar.Bar.Fill = new Fill(Color.Red, Color.White, Color.Red);
// Fix up the curve attributes a little
myCurve.Symbol.Size = 8.0F;
myCurve.Symbol.Fill = new Fill(Color.White);
myCurve.Line.Width = 2.0F;
// Fix up the curve attributes a little
myCurve.Symbol.Size = 8.0F;
myCurve.Symbol.Fill = new Fill(Color.White);
myCurve.Line.Width = 2.0F;
// Draw the X tics between the labels instead of
// at the labels
myPane.XAxis.MajorTic.IsBetweenLabels = true;
// Set the XAxis labels
myPane.XAxis.Scale.TextLabels = labels;
// Set the XAxis to Text type
myPane.XAxis.Type = AxisType.Text;
// Fill the Axis and Pane backgrounds
myPane.Chart.Fill = new Fill(Color.White, Color.FromArgb(255, 255, 166), 90F);
myPane.Fill = new Fill(Color.FromArgb(250, 250, 255));
// Tell ZedGraph to refigure the
// axes since the data have changed
zg1.AxisChange();
}
