Plotting transformed datasets does not work #79

Closed thouska closed 3 years ago

thouska commented 3 years ago

Tested with #1 groundwater head level and #13 discharge Both result in

Error

'DataFrame' object has no attribute 'time'

philippkraft commented 3 years ago

Problem was: handling of empty timeseries (in case of transformed timeseries, source dataset outside the query time).

Plotting of groundwater head level works fine now. Thx. However, transformed datasets of discharge still produce an error when plotted (e.g. ds370 and ds371 and site13 and 18):

where function returns an array instead of a Series. Fixed by transforming to series always.
