Bug report

Bug summary

Unlike the doc, the intervd dictionary has keys of integers, so the example in the doc ("only show every 3 hours") did not work.

Code for reproduction

import matplotlib.dates as mdates
locator = mdates.AutoDateLocator()
print(locator.intervald)

Actual outcome

{
0: [1, 2, 4, 5, 10, 20, 40, 50, 100, 200, 400, 500, 1000, 2000, 4000, 5000, 10000], 
1: [1, 2, 3, 4, 6], 
3: [1, 2, 4, 7, 14, 21], 
4: [1, 2, 3, 4, 6, 12],
5: [1, 5, 10, 15, 30], 
6: [1, 5, 10, 15, 30], 
7: [1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000, 20000, 50000, 100000, 200000, 500000, 1000000]
}

Expected outcome

{
    YEARLY  : [1, 2, 4, 5, 10, 20, 40, 50, 100, 200, 400, 500,
               1000, 2000, 4000, 5000, 10000],
    MONTHLY : [1, 2, 3, 4, 6],
    DAILY   : [1, 2, 3, 7, 14],
    HOURLY  : [1, 2, 3, 4, 6, 12],
    MINUTELY: [1, 5, 10, 15, 30],
    SECONDLY: [1, 5, 10, 15, 30],
    MICROSECONDLY: [1, 2, 5, 10, 20, 50, 100, 200, 500,
                    1000, 2000, 5000, 10000, 20000, 50000,
                    100000, 200000, 500000, 1000000],

Oh my bad, it imports (in the source code)

from dateutil.rrule import (rrule, MO, TU, WE, TH, FR, SA, SU, YEARLY,
                            MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY,
                            SECONDLY)

So it's not a typo. I thought string like keyword for the dict such as intervd["HOURLY"], but it was not.

But I guess a bit of explanation in the doc may be helpful :)
