Zedgraph 是一个非常好的图表库，用于在Windows应用程序中绘制图表.此代码项目文章

The Zedgraph is a very good charting library for drawing charts in Windows application. It is explained here in this Code Project article

从我链接到的网站上获取最高系数:

Take the top coefficients from the website I linked to:

// For np = 5 = 5 data points
var h = 35.0;
var coeff = new float[] { 17, 12, -3 }; // coefficients from the site
var easyCoeff = new float[] {-3, 12, 17, 12, -3}; // Its symmetrical
var center = 2; // = the center of the easyCoeff array
// now for every point from your data you calculate a smoothed point:

smoothed[x] = 
   ((data[x - 2] * easyCoeff[center - 2]) +
    (data[x - 1] * easyCoeff[center - 1]) +
    (data[x - 0] * easyCoeff[center - 0]) +
    (data[x + 1] * easyCoeff[center + 1]) +
    (data[x + 2] * easyCoeff[center + 2])) / h;

使用5个点时，前2个点和后2个点将无法平滑.

The first 2 and last 2 points you cannoth smooth when using 5 points.
