TypeError：尝试在python中调用子绘图时，无法调用“tuple”对象

Question

目前正在尝试用python制作一些子脚本。这段代码昨天就开始工作了，现在我得到了“TypeError:‘tuple’对象不可调用”

奇怪的是，它允许我在命令栏中分别运行所有这些图形，但当我运行完整的代码时，它只绘制了其中两个图形，然后给出了这个错误。我必须重新启动内核才能重新开始绘图，否则我尝试绘图的任何东西都会给出这个答案

以下是我试图编写的代码：

plt.subplot(2,2,1)
plt.plot(x_axis, avg_ANK_ang[:,0], color='red', linewidth=1, linestyle = '--')
plt.fill_between(x_axis, avg_ANK_ang[:,0]-angANKnvf_err, avg_ANK_ang[:,0]+angANKnvf_err, alpha=0.5,  facecolor='#FF9848')
plt.plot(x_axis, avg_ANK_ang[:,1], color='blue', linewidth=1)
plt.fill_between(x_axis, avg_ANK_ang[:,1]-angANKcvf_err, avg_ANK_ang[:,1]+angANKcvf_err, alpha=0.5,  facecolor='#089FFF')
plt.xticks([])
seaborn.despine(left=True, bottom=True, right=True)
plt.ylabel("Ankle")
plt.title("Angle (deg)")

plt.subplot(2,2,3)
plt.plot(x_axis, avg_MTP_ang[:,0], color='red', linewidth=1, linestyle = '--')
plt.fill_between(x_axis, avg_MTP_ang[:,0]-angMTPnvf_err, avg_MTP_ang[:,0]+angMTPnvf_err, alpha=0.5,  facecolor='#FF9848')
plt.plot(x_axis, avg_MTP_ang[:,1], color='blue', linewidth=1)
plt.fill_between(x_axis, avg_MTP_ang[:,1]-angMTPcvf_err, avg_MTP_ang[:,1]+angMTPcvf_err, alpha=0.5,  facecolor='#089FFF')               
seaborn.despine(left=True, bottom=True, right=True) 
plt.plot = (x_axis, 0)             
plt.ylabel("MTP") 
plt.xlabel("% stance")

plt.subplot(2,2,2)
plt.plot(x_axis, avg_ANK_mom[:,0], color='red', linewidth=1, linestyle = '--')
plt.fill_between(x_axis, avg_ANK_mom[:,0]-momANKnvf_err, avg_ANK_mom[:,0]+momANKnvf_err, alpha=0.5,  facecolor='#FF9848')
plt.plot(x_axis, avg_ANK_mom[:,1], color='blue', linewidth=1)
plt.fill_between(x_axis, avg_ANK_mom[:,1]-momANKcvf_err, avg_ANK_mom[:,1]+momANKcvf_err, alpha=0.5,  facecolor='#089FFF')             
plt.xticks([])
seaborn.despine(left=True, bottom=True, right=True)
plt.title("Moment (NM)")  

plt.subplot(2,2,4)
plt.plot(x_axis, avg_MTP_mom[:,0], color='red', linewidth=1, linestyle = '--')
plt.fill_between(x_axis, avg_MTP_mom[:,0]-momMTPnvf_err, avg_MTP_mom[:,0]+momMTPnvf_err, alpha=0.5,  facecolor='#FF9848')
plt.plot(x_axis, avg_MTP_mom[:,1], color='blue', linewidth=1)
plt.fill_between(x_axis, avg_MTP_mom[:,1]-momMTPcvf_err, avg_MTP_mom[:,1]+momMTPcvf_err, alpha=0.5,  facecolor='#089FFF')             
seaborn.despine(left=True, bottom=True, right=True)
plt.xlabel("% stance")

错误：

  File "/Users/Laura/Box/NVF/Biomechanics data/Compile/compile.py", line 130, in <module>
    plt.plot(x_axis, avg_ANK_mom[:,0], color='red', linewidth=1, linestyle = '--')

TypeError: 'tuple' object is not callable

另一件奇怪的事情是，它通常在给出错误之前绘制前两个图。（除非我将它们单独放在命令窗口中，否则前三个通常会打印）

Answer 1

plt.plot = (x_axis, 0)

这行代码就是问题所在。您已将plt.plot重新分配为元组变量，它不再是函数
