繪圖成像與真實值

Question

我已經得到了包含實部和虛部的複數值列表。

我要繪製與域限制假想值（在y軸）從-1到+1 VS實際值（在x軸）與域限制爲-10到10

如何我能完成這個嗎？

在此先感謝。

使用matplotlib：

values = [ 
    -19.5-1.22j, -19-0.3j, -18.5+0.68j, -18+1.5j, -17.5+1.96j, -17+1.92j, 
    -16.5+1.42j, -16+0.58j, -15.5-0.42j, -15-1.3j, -14.5-1.86j, -14-1.98j,

] 

import matplotlib.pyplot as plt 
x = [min(max(v.real, -10), 10) for v in values] 
y = [min(max(v.imag, -1), 1) for v in values] 
plt.plot(x, y) 
plt.show()
