如何使用跟踪“实时”更新matplotlib图 - python

代码中很少有锚点需要注意。

每次下拉值更改时，update_observation()函数都会更新。每当下拉列表值更改时，我也希望图形也更改。我在任何时候都只想要一个图形窗口实例。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trace方法可以替代动画。

该按钮仅用于打开和关闭窗口。它没有解决任何其他目的。它将绑定，直到未关闭同一窗口。如何在artifact_graph_window函数中使用update_observation()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))

参考方案

要注意的是要保持动画功能的范围正确，并且对于不同的窗口，画布，图形和轴的名称也必须不同。您可以设置interval和blit参数以使更新更有效。
