Вы должны использовать self.ax.
для добавления элементов
self.ax.set_xlabel('teeeest')
self.ax.set_title('Graph test')
self.ax.set_xlabel("Time")
self.ax.set_ylabel("% SMS")
, но тогда возникает другая проблема, потому что self.ax.clear()
удаляет эти элементы.
Первый метод:
Если вы используете self.ax.clear()
, тогда вы удаляете ярлыки, и вам нужно снова и снова наносить ярлыки
def animate(self, i):
self.xs.append(self.xax)
#self.ys.append(datetime.datetime.now().second)
self.ys.append(random.randint(0, 10))
self.xax += 1
self.ax.clear()
self.ax.plot(self.xs,self.ys)
if self.xax > 90:
self.anim.event_source.stop()
self.ax.set_xlabel('teeeest')
self.ax.set_title('Graph test')
self.ax.set_xlabel("Time")
self.ax.set_ylabel("% SMS")
Второй метод:
Чтобы добавить элементы только один раз, вам нужно удалить self.ax.clear()
, а вместо plot()
вы должны создать пустой график в ` init
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")
self.line, = self.ax.plot([], [])
и в анимации set_data()
для обновления данных в существующем графике
self.line.set_data(self.xs, self.ys)
, но это не приведет к изменению масштаба графика, и вам придется сделать это вручную (если вы хотите изменить масштаб)
self.ax.relim() # recalculate limits
self.ax.autoscale_view(True,True,True) # rescale using limits
