How Can I Change The X-axis Labels In A Python Plot?

I have this code : import numpy as np import pylab as plt a = np.array([1,2,3,4,5,6,7,8,9,10]) b = np.exp(a) plt.plot(a,b,'.') plt.show() The code works fine, but I need to modi

Solution 1:

import numpy as np
import pylab as plt

a = np.array([1,2,3,4,5,6,7,8,9,10])
# this is it, but better use floats like 10.0, 
# a integer might not hold values that big
b = 10.0 ** a 
plt.plot(a,b,'.')
plt.show()

Solution 2:

This code probably is what you need:

import numpy as np
import pylab as plt

a = np.asarray([1,2,3,4,5,6,7,8,9,10])
b = np.exp(a)
c = np.asarray([10**i for i in a])
print(list(zip(a,c)))
plt.xticks(a, c)
plt.plot(a,b,'.')
plt.show()

By using plt.xtick() you can customize your x-label of plot. I also replaced 10^i with 10**i.
