Python matplotlib how to scale synchronously on different plots of the same figure?

Question

Python

Hello, I'm recently using the matplotlib library. There was a need to analyze graphical data. There are several different data on the y-axis, and on the x-axis the data is 100% identical. Data is collected from different instruments at the same time. Then they are analyzed. And for the convenience of analysis, it is necessary to stretch the graph (zoom in) of a certain section along the X axis, simultaneously (synchronously) on two or more graphs, namely, stretch the same section along the X axis on other graphs automatically. How can I implement or maybe there are some other tools to do this?
Python 3.4.4, matplotlib 2.2.2

Graphs like this, you need to simultaneously increase the
piece of code where I build graphs, but there is nothing ordinary here.

self.angle = []  # угол наклона рамы
        self.angle_r = []  # угол наклона ролика
        self.pressure = []  # задаваемое давление
        self.c_pressure = []  # текущее давление
        self.c_pressure0 = []
        self.speed_rolika = []  # текущая скорость ролика
        self.nn1 = []

# Пропускаю код обработки получиченных значений
# массивы данных пипа float

# строим выбранные графики
        k = 0
        fig = plt.figure()
        fig.add_subplot(111)
        if self.ui.checkBox.isChecked():
            k += 1
            subplot(int(str(n) + str(1) + str(k)))
            plot(self.angle, self.pressure)
            plot(self.angle, self.c_pressure0)
        if self.ui.checkBox_2.isChecked():
            k += 1
            fig.tight_layout()
            subplot(int(str(n) + str(1) + str(k)))
            plot(self.angle, self.pressure)
            plot(self.angle, self.c_pressure)
        if self.ui.checkBox_3.isChecked():
            k += 1
            subplot(int(str(n) + str(1) + str(k)))
            plot(self.angle1, self.pressure1)
            plot(self.angle1, self.c_pressure_correct1)
        if self.ui.checkBox_4.isChecked():
            k += 1
            subplot(int(str(n) + str(1) + str(k)))
            plot(self.angle, self.speed_rolika)
        if self.ui.checkBox_5.isChecked():
            k += 1
            subplot(int(str(n) + str(1) + str(k)))
            plot(self.angle, self.nn1)
        plt.show()

The subplots function has key parameters ```sharex``` and ```sharey```. Well, there you can set ```all``` as a value so that the scale/shift across the entire grid is synchronized, or ```col`` and ```row``` so that only the current column or column is synchronized. Well, sort of like this for two graphs glued vertically.

fig, (ax1, ax2) = plt.subplots(2, 1, sharex='all', figsize=(640/my_dpi, 2*480/my_dpi), dpi=my_dpi)
