[英]How to put text inside a box on a plot in matplotlib
Here is the code from the example : 以下是示例中的代码:
# these are matplotlib.patch.Patch properties
props = dict(boxstyle='round', facecolor='wheat', alpha=0.5)
# place a text box in upper left in axes coords
ax.text(0.05, 0.95, textstr, transform=ax.transAxes, fontsize=14,
verticalalignment='top', bbox=props)
Matplotlib coordinates Matplotlib坐标
Using transform=ax.transAxes
we can put elements inside a plot in using coordinate system in which point (0, 0) is lower left corner, (0, 1) upper left, (1, 1) upper right, and so on. 使用
transform=ax.transAxes
我们可以使用坐标系将元素放入绘图中,其中点(0,0)是左下角,(0,1)左上角,(1,1)是右上角,依此类推。
To be specific: if we put a text box using position (0, 0) a specific point called anchor
will be placed in lower left corner. 具体来说:如果我们使用位置(0,0)放置一个文本框,则会在左下角放置一个名为
anchor
的特定点。 To change anchor you need to add two arguments to the function call: verticalalignment
(possible values: center
, top
, bottom
, baseline
) and horizontalalignment
(possible values: center
, right
, left
). 要更改锚点,您需要为函数调用添加两个参数:
verticalalignment
(可能的值: center
, top
, bottom
, baseline
)和horizontalalignment
(可能的值: center
, right
, left
)。
So to put box in lower left corner, you need to put lower left corner of the box in the lower left corner of the figure: 因此,要将框放在左下角,您需要将框的左下角放在图的左下角:
# place a text box in lower left in axes coords
ax.text(0.05, 0.05, textstr, transform=ax.transAxes, fontsize=14,
verticalalignment='bottom', bbox=props)
Anyways here is the link to ipython-notebook with example for all placements . 无论如何,这里是ipython-notebook的链接, 其中包含所有展示位置的示例 。
