How to set xlim

I have this code:

import matplotlib.pyplot as pl
pl.plot(np.log(alphas_lasso),coefs_lasso.T) #this generate a plot which xlim=[-8,-2]
for alpha in alpha_min:
    pl.axvline(np.log(alpha),0,1) #add vertical line for every value of alpha
pl.xlim([-10,0]) # the xlim value I would like to set
pl.xlabel('Log(alpha)')
pl.ylabel('coefficients')
pl.title('Lasso Path')
pl.axis('tight')
pl.show()
print "log(alpha_min)=",log(alpha_min)

It works but the x axis goes from -8 to -2 while I would like from -10 to 0 Where is the error?

You set back your xrange to default with pl.axis('tight'). Try to remove that line, or put it before the xlim command.

The pyplot documentation says for pl.axis('tight'): "changes x and y axis limits such that all data is shown."
