summary
Prefacematplotlib The default position of the drawing example is in every corner of the drawing , But sometimes the legend position will block the image and do not meet our needs , The legend position needs to be adjusted . The code is as follows ：
1.loc=‘String or Number’plt.legend(loc=‘String or Number’, bbox_to_anchor=(num1, num2))
This parameter is used to locate the approximate position of the legend ,string Parameters include
best （ Automatically find the best position , But sometimes it doesn't meet our expectations ）
upper right（ Upper right corner ）
upper left （ top left corner ）
lower left （ The lower left corner ）
lower right （ The lower right corner ）
right （ Right , and center right Same position ）
center left （ Center left ）
center right （ Center right ）
lower center（ Center down ）
upper center（ Above the middle ）
center（ precise middle ）
Its position in the table is as follows ：
Of course, parameters can also be passed in numbers as shown in the figure .
Sometimes the first parameter alone can not meet our expectations , For example, legends are stacked together , At this time, you need to adjust the second parameter .
num1 Used to control the legend Moving left and right , The bigger the value is. , Move to the right ;
num2 Used to control the legend Moving up and down , The bigger the value is. , Moving up .
3. Take a chestnut ：（1） plt.legend([‘ legend ’],loc=‘center’) or loc=10
（2） plt.legend([‘ legend ’],loc=‘center left’) or loc=6
Fine tune again
