在.NET环境下绘制模糊数学中隶属函数分布图

在.NET情况下绘制隐隐数学中附属函数散播图的全部源代码如下:

此中:unit代表图形放大年夜倍数,数值越大年夜图形放大年夜倍数越大年夜。

interval代表步进刻度,值越小越正确(必须大年夜小0),但速率也越慢。

首先:重载 pictureBox1_Paint 函数

进行画图时思惟很简单,确定肇端位置,停止位置,本法度榜样中我用System.Drawing.PointF工具存储点坐标。

应用 e.Graphics.DrawLine(Pens.Black, 坐标1, 坐标2)进行线条的绘制。

下面我将拿绘制正态散播图形先容下:

法度榜样段如下:

for (d = a; d

先确定肇危坐标(x1,y1),再结合正态散播在增添一个步进刻度的环境下确定(x2,y2),接下来调用e.Graphics.DrawLine进行画图。

着末还有一点,因为每次从新画图的时刻都要调用private void pictureBox1_Paint(object sender,PaintEventArgs e),其不是用户定义措施,以是用户句柄从新获取PictureBox_Paint措施,从新绘制图形,代码段如下:

Graphics g = Graphics.FromHwnd(this.pictureBox1.Handle);

PaintEventArgs e1 = new PaintEventArgs(g, this.pictureBox1.ClientRectangle);

this.pictureBox1_Paint(this.pictureBox1, e1);

g.Dispose();
