Hi Anushree,

Could you give a short example of the code that is failing? I have no idea what "cursor" is in this context.

Yours sincerely,

dear Simon,

        I just want to know the exact xy position of a point in  a figure and that's why I wanted to import Cursor, like we did in python3.

'from qutip import *
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import Cursor'

then to add this feature in a figure,I did

fig,ax=plt.subplots()
p,=plt.plot(time,np.real(Qt),color='red', linestyle='dashed', linewidth = 3)
cursor=Cursor(ax,horiZon=True,verTon=True,useblit=True,color='r',
             linewidth=2)
plt.show()

But I could not manage to add it. My aim is to just know the exact xy position of any point of a plot. if there is any other option in which we can do this or any references, please  let me know.

regards

Anushree

Hi Anushree,

I see. I guess this is more of an issue using matplotlib than QuTiP,
but what was the error you got or what went wrong?

Simon
