由於需要分析機械加工過程中各個軸的速度，於是用軟體匯出了資料，寫了這個python指令碼來顯示速度曲線。
效果圖如下：

file = open(path, 'r')
amat = ; bmat = ;xmat = ;ymat = ;zmat = ;
for line in file.readlines():
linearr = line.strip().split()
amat.append(int(linearr[0]))
bmat.append(int(linearr[1]))
xmat.append(int(linearr[2]))
ymat.append(int(linearr[3]))
zmat.append(int(linearr[4]))
