[FIXED] How to display a text with matplotlib

Issue

I would like to do this :

I have this python code :

import numpy as np
import pylab as plt

a = np.array([1,2,3,4,5,6,7,8,9,10])
b = np.array([7,8,6,3,2,1,5,8,4,15])
c = plt.plot(a,b,'.')
d = 5
plt.text(2,3, "d = "+d) #This line is the problem because i have not the value of d !
plt.show()

So actually I just want to display the value of d and also I want to display the value of d but relatively for instance at the bottom right but not with some coordinates. Is it possible to do this with Python ?

Solution

You can use the transform argument to place in relative coordinates from 0.0 to 1.0 for example

plt.text(0.5,
         0.67,
         "d = {}".format(d),
         transform=plt.gca().transAxes)

In this local system (0, 0) is the lower-left and (1, 1) is the upper-right of the plot. Here is a good reference for placing and rotating text at various locations on the plot.
