String X or Y ticks label in plotting graph of Python using matplotlib

In usual case, we are plotting graphs about integer or float x or y values, but sometimes you need to plot some graphs using string x or y values such as dates, categories.

In this case, you can easily draw plot with string values by using xticks or yticks module.


In this post, I will show you an example using x string values.


Just for integer plot

-----------------------------------------------------------------------------

from pylab import *

x = [ 1, 2, 3 ]
y = [ 2, 5, 10 ]

plot(x, y)

show()

-----------------------------------------------------------------------------

The results is like below

Now, for string x values

---------------------------------------------------------------------
from pylab import *

x = [ 'Mon', 'Tue', 'Wed' ]
y = [ 2, 5, 10 ]

plot(range(len(y)), y)
xticks(range(len(y)), x, size='small')
show()

--------------------------------------------------------------------

Eventually, you can get the graph with string x labels described as below

Thanks,

Have Fun!
