"""Plots that represent data with sound and can be checked interactively
You can interactively check the data in graph form by moving the mouse cursor.
When you enter or leave the graph image, you will be notified by voice.
Also, when you move the mouse left or right on the graph image,
the y-axis value corresponding to that location will be expressed with a high or low tone.
A single click will read out the value corresponding to that location.
Also, double-clicking switches the group according to the label specified as an option.
Parameters
----------
y : list
A list of values to be graphed.
x : list
A list of x-axis values corresponding to y-axis values.
If not specified, it is substituted by the value of the equal interval. Optional.
label : list
A list of grouping numbers for each value, which must start with zero.
You can compare the graph data by sound, switching between each number. Optional.
width : int
Width of the graph image (in pixels). Optional.
height : int
Height of the graph image (in pixels). Optional.
title: str
Graph name to be read out. Optional.
multiple_axes: bool
Set to True if you want each label to have a separate y-axis. Optional.
Examples
--------

>>> plot(x=[0, 1, 2], y=[4, 5, 6], label=[0, 0, 1])
