我有一个包含大约3000个项目的列表（每个项目都是10个点的列表）。一个项目可能如下所示：
[['-19.05364812189936' '-8.078571934798015']
['-4.481956059532247' '10.88512402551382']
['-15.985506732813608' '-19.92397590361446']
['-1.2933416017009214' '-10.233128986534373']
['-19.640113394755492' '2.7974946846208364']
['-9.466119773210488' '1.8171420978029766']
['4.998052799433026' '-0.5782990786676117']
['-7.883010276399716' '-9.731805457122608']
['-2.754521615875266' '-18.244450744153085']
['-17.105912473423103' '13.09440644932672']
['right' '0']]
我最终想要的是绘制第一个项目，进行一些用户交互（为绘制的点指定标签），确认（保存到另一个列表：10个点+标签）并绘制下一个项目，依此类推。
这是我目前的代码：
import numpy as np
import Utils as utils
import matplotlib.pyplot as plt
methods = utils.ClusteringMethods()
db = utils.DbConnection()
formations = methods.readFromDump('testNewInterval')
formation_list = []
formation_list.append('5-3-2')
formation_list.append('4-4-2')
formation_list.append('4-3-3')
labelled_formations = []
def add_formation_def():
name = input('Please specify formation')
if(name not in formation_list):
formation_list.append(name)
else:
print('Already there, please try again')
def showOptionList():
for idx, item in enumerate(formation_list):
print(idx, ' - ', item)
def getCurrentFormation(index):
return formations[index]
def showClearPlot():
ax1.clear()
ax1.imshow(im, extent=[-55, 55, -35, 35], aspect='auto')
def nextPlot():
print('in next plot..')
global currentIndex
global currentFormation
currentIndex = currentIndex +1
ax1.clear()
ax1.imshow(im, extent=[-55, 55, -35, 35], aspect='auto')
currentFormation = getCurrentFormation(currentIndex)
showPlot(currentFormation)
def showPlot(currentFormation):
orientation = currentFormation[-1][0]
print('orientation: ', orientation)
currentFormation = currentFormation[:-1]
for point in currentFormation:
ax1.plot(float(point[0]), float(point[1]), '.', markersize=14, mfc='darkgreen', mec='k')
plt.show()
def on_key(event):
print('key: ', event.key)
if (event.key == ' '):
showOptionList()
if (event.key == 'f1'):
add_formation_def()
if(event.key == 'f2'):
nextPlot()
#Initialize Pitch
fig = plt.figure(figsize=(11,6))
ax1 = fig.add_subplot(111)
im = plt.imread('field.png')
ax1.imshow(im, extent=[-55, 55, -35, 35], aspect='auto')
#register events
cid = fig.canvas.mpl_connect('key_press_event', on_key)
currentIndex = 0
currentFormation = formations[currentIndex]
showPlot(currentFormation)
它适用于一些项目，但最终我收到以下错误：

我猜它是因为广泛使用
plt.show()
showplot()中的。
我还阅读了很多关于使用交互模式（ion()）并将.show()替换为.draw()的内容，这对我来说并不合适，因为它不会显示任何情节。
