问题描述
下图是使用 MATLAB 创建的.我想在 Windows 窗体中有完全相同的图.
The following plot was created with MATLAB. I want to have the excact same plot in windows forms.
但是,将多个 y 值绘制为一个 x 值(在本例中为 0)是行不通的.
However, it does not work out to plot several y-values to one x-value (in this case: 0).
我的代码
this.chart3.Series["Series1"].Points.Clear();
this.chart3.Series["Series1"].Points.AddXY(0, doubleValueArray); //length is 1600
this.chart3.Update();
但我收到错误
Exception was thrown: Series data points do not support values of type
System.Double[] only values of these types can be used: Double, Decimal,
Single, int, long, uint, ulong, String, DateTime, short, ushort.
...我不明白,因为基于 文档 AddXY 的第二个参数接受双数组.
...what I do not understand, because based on the documentation the second parameter of the AddXY accepts an double array.
我是否需要设置其他东西,例如在属性?
Do I need to setup something else e.g. in the properties?
感谢您的帮助
推荐答案
AddXY
函数需要两个数组:
this.chart3.Series["Series1"].Points.AddXY(xArray, yArray);
在 xArray 中有单个数据点的 x 值.所以在你的情况下,它应该是一个有 1600 个零的数组.
In xArray there a the x-values of the single data points. So in your case it should be an array with 1600 zeros.
更新:
你必须添加
this.chart3.Series["Series1"].CustomProperties = "IsXAxisQuantitative=True";
否则它不会在 x=0 轴上工作
otherwise it will not work on the x=0 axis
我在自己的问题中表述了该轴上的问题:在 MS 图表控件中为 x=0 绘制两个 y 值
I formulated the problem on that axis in an own question: Plotting two y-values for x=0 in a MS Chart control
