python 100 days 61 pie function to draw pie chart effect control

Continuing the basics of pie charts above, if you want to continue to control the effect color of pie charts, etc

The default color is like this

At this point we need to define a color for the first pie chart area

Add a color configuration item.

mycolors = ["black",
                    "hotpink",
                    "b",
                    "#4CAF50"
           ]

plt.pie(y, labels = mylabels, \
          startangle = 90, \
          explode = myexplode
          ,colors = mycolors
)           

What if you want to achieve such an effect?

plt.pie(y, labels = mylabels, \
startangle = 90, \
explode = myexplode
,colors = mycolors
)
plt.legend()
           

• plt.legend() plus this method adds a summary to the diagram

If you want to achieve the following effect?

plt.legend(title = "Four Fruits :")

plt.show()           

Finally, what effect would it have if Chinese title was added? You can try it in the cloud.
