Add functions to configure both axis

[ediordna]

Consider adding functions for configuring x- and y-axis:

    def configure_x_axis(self, position: float = 4.9, horizontal_time: int = 10):
        '''Configures the horizontal x-axis to the correct range and position.
        It is only possible to configure it in this order, otherwise an error is raised.

        :param position: interval between trigger and reference point in seconds, defaults to 4.9
        :type position: int, optional
        :param horizontal_time: full-scale horizontal time in seconds, defaults to 10
        :type horizontal_time: int, optional
        :raises ValueError: If writing of Position wasn't successful
        :raises ValueError: If writing of Range wasn't successful
        '''
        # sets the full-scale horizontal time range in seconds for the main window
        self.write_raw(f':TIMebase:RANGe {horizontal_time}')
        if float(self.query_raw(':TIMebase:RANGe?')) != float(horizontal_time):
            raise ValueError('Osci: Timebase:RANGe not set successful!')
        # sets the time interval between trigger event and display reference point on the screen
        self.write_raw(f':TIMebase:POSition {position}')
        if float(self.query_raw(':TIMebase:POSition?')) != float(position):
            raise ValueError('Osci: TIMebase:POSition not set successful!')

    def configure_y_axis(self, channel: int, v_range: int, v_offset: int=0):
        '''Defines the full-scale vertical axis (8 parts) of the selected channel.

        :param channel: choose a channel from 1 to 4
        :type channel: int
        :param v_range: defines the vertical range, e.g. 8 for 1A/
        :type v_range: int
        :param v_offset: defines the vertical offset from the center screen to the bottom,
                         defaults to 0
        :type v_offset: int
        '''
        self.write_raw(f':CHANnel{channel}:RANGe {v_range}')
        if float(self.query_raw(f':CHANnel{channel}:RANGe?')) != float(v_range):
            raise ValueError('Osci: CHANnel:RANGe not set successful!')
        self.write_raw(f':CHANnel{channel}:OFFSet {v_offset}')
        if float(self.query_raw(f':CHANnel{channel}:OFFSet?')) != float(v_offset):
            raise ValueError('Osci: CHANnel:OFFSet not set successful!')
