How to specify values on y axis of a matplotlib plot
matplotlib, plot, python, python-2.7
Solution
import matplotlib.pyplot as plt
import numpy as np
x = np.array([0,1,2,3])
y = np.array([0.650, 0.660, 0.675, 0.685])
my_xticks = ['a', 'b', 'c', 'd']
plt.xticks(x, my_xticks)
plt.yticks(np.arange(y.min(), y.max(), 0.005))
plt.plot(x, y)
plt.grid(axis='y', linestyle='-')
plt.show()
Something like this should work.
Problem
I need to generate a graph using matplotlib like the one in the attached picture. So far I tried it like this: ``` import matplotlib.pyplot as plt import numpy as np x = np.array([0,1,2,3]) y = np.array([20,21,22,23]) my_xticks = ['John','Arnold','Mavis','Matt'] plt.xticks(x, my_xticks) plt.plot(x, y) plt.show() ``` How can I specify a different number of values on the y axis different from the number of values on the x axis? And maybe specify them as an interval with 0.005 difference instead of a list?
