【问题描述】：
代码中需要注意的锚点很少。
每次下拉值更改时，update_observation() 函数都会更新。每当更改下拉列表值时，我希望图表也随之更改。在任何时候我都只想要一个图形窗口的实例。我想更新图形窗口内的信息。我尝试使用动画，但我相信使用跟踪方法可以替代它。
按钮只是用来打开和关闭窗口。它没有解决其他目的。它一直绑定到同一个窗口没有关闭。如何在 update_observation() 函数中使用 artifact_graph_window 的值。
def tab_two_load(self,tab1_open_observations):
def update_observation(a,b,c):
proj_name,mod_name = observation_project_value.get().split(" -- ")
observations_fr_project = db.query_findings_by_project(proj_name,mod_name)
##CONFIG
fig = Figure(figsize=(6,6))
a = fig.add_subplot(111)
## DATA
x_cat = [x[1] for x in db.query_artifact()]
x_cat = x_cat[:-2]
y_count = {}
for i in x_cat:
y_count[i] = 0
for i in observations_fr_project:
y_count[i[2]] = y_count[i[2]] + 1
print(y_count)
x = y_count.keys()
y = y_count.values()
## PLOT
a.bar(x,y,color='blue')
## SHOW
a.set_title ("Artifact Breakdown", fontsize=16)
a.set_ylabel("Breakdown", fontsize=14)
a.set_xlabel("Artifact Type", fontsize=14)
a.yaxis.set_major_locator(MaxNLocator(integer=True))
