滑块不工作并更新图中的值
Slider not working and updating values in graph
当我更改滑块时，以下代码不会更新图表。滑块由我想更改的两个变量 Ao 和 Au 组成。最初 Ao 设置为 600，Au 设置为 800。随着滑块的移动，我预计图形会发生变化，但这是行不通的。我在做什么错？如果可能的话，请告诉我制作四个滑块的方法，当我改变它们时它们可以一起工作，它们是 Ao、Au、Bo 和 Bu。

先提一个普遍的建议：这段代码真的很难读。考虑把它拆成更小的部分，也许你可以重复使用一些部分。
所以对于你的问题：slider.on_change(fun) 需要一个函数，当滑块的值发生变化时应该调用该函数。现在你只是传递了一个 int/float.
为了执行此更新，您需要一个函数，它为您提供要为给定的 (Ao, Au, Bo, Bu) 组合绘制的值。为了快速修复，我只是将所有内容放在一个函数中 fun，但你真的应该考虑以更有意义的方式构建它：
def fun(Ao, Au, Bo, Bu):
inten=[]
wave=[]
rrrinten=[]
if deltaJ == 0:
...
elif deltaJ == 1:
...
elif deltaJ == -1:
...
else:
...
s1 = np.size(wave)
print("no of waves=", s1)
...
s = z*rrrinten1.reshape((-1, 1))
s = s.sum(axis=0)
return (wave, rrrinten), (xvalues, s)
有了这个函数我们可以先初始化绘图：
Ao_init = 600
Bo_init = 0
Au_init = 800
Bu_init = 0
(x1, y1), (x2, y2) = fun(Ao=Ao_init, Au=Au_init, Bo=Bo_init, Bu=Bu_init)
fig, ax = plt.subplots()
plt.subplots_adjust(bottom=0.30)
h_stem = plt.stem(x1, y1, use_line_collection=True)
h_plot = plt.plot(x2, y2, '--r')[0]
和滑块，然后编写更新函数：
axcolor = 'lightgoldenrodyellow'
ax_bu = plt.axes([0.2, 0.25, 0.65, 0.03], facecolor=axcolor)
ax_bo = plt.axes([0.2, 0.2, 0.65, 0.03], facecolor=axcolor)
ax_ao = plt.axes([0.2, 0.15, 0.65, 0.03], facecolor=axcolor)
ax_au = plt.axes([0.2, 0.1, 0.65, 0.03], facecolor=axcolor)
s_bu = Slider(ax_bu, 'Bu', -100, 100, valinit=Bo_init, valstep=1, valfmt='%i')
s_bo = Slider(ax_bo, 'Bo', -100, 100, valinit=Bu_init, valstep=1, valfmt='%i')
s_ao = Slider(ax_ao, 'Ao', 0, 1000, valinit=Au_init, valstep=1, valfmt='%i')
s_au = Slider(ax_au, 'Au', 0, 1000, valinit=Ao_init, valstep=1, valfmt='%i')
def on_changed(event):
# Get new values
(x1, y1), (x2, y2) = fun(Ao=s_au.val, Au=s_ao.val, Bo=s_bo.val, Bu=s_bu.val)
ax.set_xlim((min(min(x1), min(x2)),
max(max(x1), max(x2))))
# update plot
h_plot.set_ydata(y2)
h_plot.set_xdata(x2)
# update stem
h_stem[0].set_ydata(y1)
h_stem[0].set_xdata(x1)
h_stem[1].set_paths([np.array([[x, 0], [x, y]]) for (x, y) in zip(x1, y1)])
h_stem[2].set_xdata([np.min(x1), np.max(x1)])
fig.canvas.draw_idle()
s_au.on_changed(on_changed)
s_ao.on_changed(on_changed)
s_bo.on_changed(on_changed)
s_bu.on_changed(on_changed)

当我更改滑块时，以下代码不会更新图表。滑块由我想更改的两个变量 Ao 和 Au 组成。最初 Ao 设置为 600，Au 设置为 800。随着滑块的移动，我预计图形会发生变化，但这是行不通的。我在做什么错？如果可能的话，请告诉我制作四个滑块的方法，当我改变它们时它们可以一起工作，它们是 Ao、Au、Bo 和 Bu。

先提一个普遍的建议：这段代码真的很难读。考虑把它拆成更小的部分，也许你可以重复使用一些部分。
所以对于你的问题：slider.on_change(fun) 需要一个函数，当滑块的值发生变化时应该调用该函数。现在你只是传递了一个 int/float.
为了执行此更新，您需要一个函数，它为您提供要为给定的 (Ao, Au, Bo, Bu) 组合绘制的值。为了快速修复，我只是将所有内容放在一个函数中 fun，但你真的应该考虑以更有意义的方式构建它：
def fun(Ao, Au, Bo, Bu):
inten=[]
wave=[]
rrrinten=[]
if deltaJ == 0:
...
elif deltaJ == 1:
...
elif deltaJ == -1:
...
else:
...
s1 = np.size(wave)
print("no of waves=", s1)
...
s = z*rrrinten1.reshape((-1, 1))
s = s.sum(axis=0)
return (wave, rrrinten), (xvalues, s)
有了这个函数我们可以先初始化绘图：
Ao_init = 600
Bo_init = 0
Au_init = 800
Bu_init = 0
(x1, y1), (x2, y2) = fun(Ao=Ao_init, Au=Au_init, Bo=Bo_init, Bu=Bu_init)
fig, ax = plt.subplots()
plt.subplots_adjust(bottom=0.30)
h_stem = plt.stem(x1, y1, use_line_collection=True)
h_plot = plt.plot(x2, y2, '--r')[0]
和滑块，然后编写更新函数：
axcolor = 'lightgoldenrodyellow'
ax_bu = plt.axes([0.2, 0.25, 0.65, 0.03], facecolor=axcolor)
ax_bo = plt.axes([0.2, 0.2, 0.65, 0.03], facecolor=axcolor)
ax_ao = plt.axes([0.2, 0.15, 0.65, 0.03], facecolor=axcolor)
ax_au = plt.axes([0.2, 0.1, 0.65, 0.03], facecolor=axcolor)
s_bu = Slider(ax_bu, 'Bu', -100, 100, valinit=Bo_init, valstep=1, valfmt='%i')
s_bo = Slider(ax_bo, 'Bo', -100, 100, valinit=Bu_init, valstep=1, valfmt='%i')
s_ao = Slider(ax_ao, 'Ao', 0, 1000, valinit=Au_init, valstep=1, valfmt='%i')
s_au = Slider(ax_au, 'Au', 0, 1000, valinit=Ao_init, valstep=1, valfmt='%i')
def on_changed(event):
# Get new values
(x1, y1), (x2, y2) = fun(Ao=s_au.val, Au=s_ao.val, Bo=s_bo.val, Bu=s_bu.val)
ax.set_xlim((min(min(x1), min(x2)),
max(max(x1), max(x2))))
# update plot
h_plot.set_ydata(y2)
h_plot.set_xdata(x2)
# update stem
h_stem[0].set_ydata(y1)
h_stem[0].set_xdata(x1)
h_stem[1].set_paths([np.array([[x, 0], [x, y]]) for (x, y) in zip(x1, y1)])
h_stem[2].set_xdata([np.min(x1), np.max(x1)])
fig.canvas.draw_idle()
s_au.on_changed(on_changed)
