ax2.scatter(X2, Y2, s=10, c='r', marker="o", label='second')
plt.legend(loc='upper right');
plt.show()

It gave me the figure as shown below: Figure 1:

But I want to achieve the following figure: Figure 2:

I want the Red curve reversed but with the axis of the Blue curve. I mean the high of Red and blue should be at the same position and the red one is reversed.

Please suggest me what I can do to achieve what I want.
