I need text at the x-axis in Matplotlib graph. I have:
import matplotlib.pyplot as plt
x=[1,2,3,4,5,6,7,8,9,10,11,12]
y=[5.3, 6.1, 25.5, 27.8, 31.2, 33.0, 33.0, 32.8, 28.4, 21.1, 17.5, 11.9]
plt.bar(x,y, color='g')
plt.xlabel('x')
plt.ylabel('y')
plt.title("Max Temperature for Months")
plt.legend()
plt.show()
And my output is:
I don't know how to replace x=[ ] list with text (strings), it gives me error.
My desired graph is:
Use the plt.xticks() function as follows:
import matplotlib.pyplot as plt
x=[1,2,3,4,5]
y=[1,2,3,4,5]
plt.bar(x,y, color='g')
plt.xlabel('x')
plt.ylabel('y')
Generate some labels to go on your graph. The list of strings must be the same length as your x and y lists:
LABELS = ["M","w","E","R","T"]
Plot them with the following:
plt.xticks(x, LABELS)
plt.title("Max Temperature for Months")
plt.legend()
plt.show()
See example here: http://matplotlib.org/examples/ticks_and_spines/ticklabels_demo_rotation.html
Edit: For information on adjusting the location/orientation/position of your labels, see the matplotlib api documentation, and this question: matplotlib ticks position relative to axis.

Edit: To achieve the location and orientation that you need, you will find a great example in this question: Matplotlib Python Barplot: Position of xtick labels have irregular spaces between eachother.
Implementing:
b = plt.bar(x,y, color='g')
xticks_pos = [0.5*patch.get_width() + patch.get_xy()[0] for patch in b]
plt.xticks(xticks_pos, LABELS,rotation = 45)
