如何根据 x 轴上的值绘制多种颜色

Question

Hey guys let's say I have a pandas DataFrame

   Year  Delta_T
0  2000       23
1  2001       25
2  2002       22
2  2002       22
4  2004       30
5  2005       21

and I want to plot delta_T in function of time but I want to plot one color for the dates from 2000 to 2003 and another color from 2004 to 2005 Can someone please tell me how I can do it?

I have tried this

plt.figure()
plt.scatter(delta_T_all.iloc[:,0].pd.Timestamp('2010-04-17'),
pd.Timestamp('2016-01-01'),delta_T_all.iloc[:,1], label= '220-250m'),
plt.scatter(delta_T_all.iloc[:,0].pd.Timestamp('2016-01-01'),
pd.Timestamp('2019-09-14'),delta_T_all.iloc[:,1], label= '220-250m')
plt.xlabel('Time')
plt.setp(plt.gca().get_xticklabels(), rotation=60, ha="right")
plt.ylabel('Delta_T')
plt.legend()
plt.title('Delta_T in function of time')

Answer 1

This is the answer

plt.figure()
plt.scatter(delta_T_all.iloc[0:2,0],delta_T_all.iloc[0:2,1],color='r')
plt.scatter(delta_T_all.iloc[2:5,0],delta_T_all.iloc[2:5,1],color='b')
plt.xlabel('Time')
plt.ylabel('Delta_T')
plt.legend()
