问题描述
还有其他人对此有疑问吗？我关注了文档，但未显示按钮。它只是创建一个空的div。控制台中没有错误。

import numpy as np
x = [1,2,3,4,5,6,7,8,9,10]
y = [700,-700,710,-710,720,-720,730,-730,740,-740]
x = np.array(x)
y = np.array(y)
mask = y >= 0 # positive mask
pos_y = y[mask] # get the positive values
neg_y = y[~mask] # get the negative values; ~ is not
fig,(ax1,ax2) = plt.subplots(2,1,figsize=(7,5))
ax1.bar(x[mask],pos_y) # also mask x to plot the bar at the correct x-tick
ax1.set_title('Positive Values')
ax1.set_ylim(min(pos_y),max(pos_y))
ax1.set_xticks(range(0,12)) # buffer the number of x-ticks,so the x-ticks of the two plots align.
ax2.bar(x[~mask],neg_y)
ax2.set_title('Negative Values')
ax2.set_ylim(min(neg_y),max(neg_y))
ax2.set_xticks(range(0,12))
plt.tight_layout() # better spacing between the two plots

解决方法
我知道了。所以我不得不将HelloButton函数放在$（document）.ready（）
