Args:
master (Widget): Parent widget
arcoffset (int): The amount to offset the arc's starting position in degrees; 0 is at 3 o'clock.
arcrange (int): The range of the arc in degrees from start to end.
amounttotal (int): The maximum value of the meter.
amountused (int): The current value of the meter; displayed if ``showvalue=True``.
interactive (bool): Enables the meter to be adjusted with mouse interaction.
labelfont(Font or str): The font of the supplemental label.
labelstyle (str): The ttk style used to render the supplemental label.
labeltext (str): Supplemental label text that appears `below` the center text.
metersize (int): The size of the meter; represented by one side length of a square.
meterstyle (str): The ttk style used to render the meter and center text.
metertype (str): One of **full** or **semi**; displays a full-circle or semi-circle.
meterthickness (int): The thickness of the meter's progress bar.
showvalue (bool): Show the meter's value in the center text; default = True.
stripethickness (int): The meter's progress bar can be displayed in solid or striped form. If the value is
greater than 0, the meter's progress bar changes from a solid to striped, where the value is the
thickness of the stripes.
textappend (str): A short string appended to the center text.
textfont (Font or str): The font of the center text.
textprepend (str): A short string prepended to the center text.
wedgesize (int): If greater than zero, the width of the wedge on either side of the current meter value.
