python - Matplotlib tick frequency -


i have list of dates plotting against list of scores. 

date = ['5/25/2015', '5/25/2015', '5/3/2015', '2/4/2015', '2/1/2015', '1/25/2015', '12/31/2014', '10/9/2014', '8/26/2014', '7/24/2014', '7/3/2014', .....]`  scores = [6.497, 14.915, 9.911, 9.908, 11.99, 10.993, 14.987, .... ]

with equal number of both.

i generating graph follows: 

figscore = plt.figure()  plt.plot(range(len(scores)), scores) plt.xticks(range(len(scores)), date, size = "small", rotation = 90) plt.tight_layout()  name = 'plot.png' figscore.savefig(name)

(no image due <10 rep)

however, can not change tick frequency. x-labels appear every 5 dates on x-axis. have tried multiple methods fix , not work.

not sure if simplest way it, 1 way make list blank except every fifth date. instance:

plotdate = [] idx, val in enumerate(date):     if idx%5 == 0:         plotdate.append(val)     else:         plotdate.append('')

and use plotdate list in call plt.xticks rather date variable. seemed work me.
