Hmm. Normally I would expect matplotlib to pop up a graph there. Are you running this from a terminal, or from some sort of GUI? It might make a difference to how it brings up the graph. Interestingly, I'm not able to run your example on my system: >>> pd.__version__ '0.17.1' >>> pd.date_range('1/1/2000', periods=1000) ValueError: Error parsing datetime string "1/1/2000" at position 1 During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.6/site-packages/pandas/tseries/index.py", line 1923, in date_range closed=closed, **kwargs) File "/usr/local/lib/python3.6/site-packages/pandas/util/decorators.py", line 89, in wrapper return func(*args, **kwargs) File "/usr/local/lib/python3.6/site-packages/pandas/tseries/index.py", line 237, in __new__ ambiguous=ambiguous) File "/usr/local/lib/python3.6/site-packages/pandas/tseries/index.py", line 379, in _generate start = Timestamp(start) File "pandas/tslib.pyx", line 299, in pandas.tslib.Timestamp.__new__ (pandas/tslib.c:8973) File "pandas/tslib.pyx", line 1163, in pandas.tslib.convert_to_tsobject (pandas/tslib.c:22522) File "pandas/tslib.pyx", line 1271, in pandas.tslib.convert_str_to_tsobject (pandas/tslib.c:24121) File "pandas/src/datetime.pxd", line 141, in datetime._string_to_dts (pandas/tslib.c:80505) SystemError: <class 'str'> returned a result with an error set So it's possible you've run into something that's changed between versions. Your original example works on my 2.7, although it doesn't pop up a graph. So now I'm a bit lost. :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
