matplotlib.pyplot.text(x, y, s, fontdict=None, withdash=<deprecated parameter>, **kwargs)[source]

向坐标轴添加内容，x,y代表添加文字的位置的坐标。

Add text to the axes.

Add the text s to the axes at location x, y in data coordinates.

Parameters:	x, y : scalars The position to place the text. By default, this is in data coordinates. The coordinate system can be changed using the transform parameter. s : str The text. fontdict : dictionary, optional, default: None A dictionary to override the default text properties. If fontdict is None, the defaults are determined by your rc parameters. withdash : boolean, optional, default: False Creates a TextWithDash instance instead of a Text instance.
Returns:	text : Text The created Text instance.
Other Parameters:	**kwargs : Text properties. Other miscellaneous text parameters.

Examples

Individual keyword arguments can be used to override any given parameter:

>>> text(x, y, s, fontsize=12)

The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords (0,0 is lower-left and 1,1 is upper-right). The example below places text in the center of the axes:

>>> text(0.5, 0.5, 'matplotlib', horizontalalignment='center',
...      verticalalignment='center', transform=ax.transAxes)

You can put a rectangular box around the text instance (e.g., to set a background color) by using the keyword bbox. bbox is a dictionary of Rectangle properties. For example:

>>> text(x, y, s, bbox=dict(facecolor='red', alpha=0.5))
