'''Yugang May 15, 2017
Get a archived PV value
Input:
start time: str, e.g., '2017-04-11 09:00',
end time: str, e.g., '2017-04-12 11:00'
label: str, a meaningful label for the pv
limit: integer, the limit data point
make_wave: if True, make a 'square-wave like' data
interpolation: 'raw', gives the raw archived data
Return: a pandas.dataframe with column as
datetime, float time, and value
data
An example:
data = get_archived_pv('XF:11IDA-OP{Mono:DCM-Ax:Bragg}T-I', '2017-04-11 09:00', '2017-04-11 11:00')
