关于如何添加颜色的散点图？

Question

The code could plot but it just has one color. So it could not figure out the color of 4 areas.

What should be added for it?

  from matplotlib import pyplot as plt 
  %matplotlib inline

  plt.title("rate in four areas")
  plt.ylabel("rate") #Y axis label
  plt.xlabel("Year")
  plt.scatter(df['Year'], df['rate'])

  plt.tight_layout()
  plt.legend(bbox_to_anchor=(1, 1))
  plt.show()

Answer 1

Is df_three a tuple containing lists, such that df_three['Year'] is a list in itself? Or does df_three['Year'] have three lists in each element, and you're plotting them all together at the same time.

If the latter is true, try

plt.scatter(df_three['Year'][0], df_three['co2'])
plt.scatter(df_three['Year'][1], df_three['co2'])
plt.scatter(df_three['Year'][2], df_three['co2'])
plt.scatter(df_three['Year'][3], df_three['co2'])

Not the most elegant solution but I'm not sure what you're doing because you haven't provided enough information.
