clist=[(-1.2720626442476508, 0.023952387163360456),
      (1.509233613482305, -1.196551723413994),

fig = plt.figure()
ax = plt.axes(xlim=(-2, 200), ylim=(-2, 2))
plt.plot(clist,'ro')
plt.show()

如您所见,x坐标超过值2.y坐标是正确的.

Answer 1

plt.plot(array)将在x坐标序列上绘制假定y坐标的数组.您需要明确传递plt.plot(xdata,ydata)以正确绘图.

在这种情况下plot(array),将输入表示:x = 0处的(y值,y值),x = 1处的(y值,y值)等.
