我如何更改Tkinter窗口中具有图形的子图参数？例如，我想添加xlabel和ylabel

Question

我有一个应用程序，应该将来自传感器的数据获取到实时图形中，并将其添加到图形中。添加子图后，我现在有一个问题，我不知道如何将图参数更改为xlabel，ylabel。如果导入plt，此方法有效，但如果导入将进一步添加到Tkinter窗口中的图形，则无效。

class liveGraph:

    #by default define the interval as being 1000 mSec
    intervalAnim = 1000

    def __init__(self,fig):
        self.xax = 0
        self.xs = []
        self.ys = []

        self.ax = fig.add_subplot(111)
        self.ax.set_xlabel('teeeest')
        #fig.title('Graph test')
        #fig.set_xlabel("Time")
        #fig.ylabel("% SMS")

        self.anim = animation.FuncAnimation(fig, self.animate, interval = self.intervalAnim)

    def animate(self,i):

        self.xs.append(self.xax)
        self.ys.append(datetime.datetime.now().second)
        self.xax+=1

        self.ax.clear()
        self.ax.plot(self.xs,self.ys)

        if self.xax > 90:
            self.anim.event_source.stop()

Answer 1

您可以使用self.ax添加元素

    self.ax = fig.add_subplot(111)
    self.ax.set_xlabel('teeeest')
    self.ax.set_title('Graph test')
    self.ax.set_xlabel("Time")
    self.ax.set_ylabel("% SMS")

但是您必须从动画中删除self.ax.clear()，然后将其删除
