Description
This a minor enhancement proposal. At the moment I cannot submit a pull request. I will probably have time to create one during the next week.
This is a snippet from tools/plotting.py: https://github.com/pydata/pandas/blob/master/pandas/tools/plotting.py#L2269-2283
def _plot(data, x=None, y=None, subplots=False,
ax=None, kind='line', **kwds):
kind = _get_standard_kind(kind.lower().strip())
if kind in _all_kinds:
klass = _plot_klass[kind]
else:
raise ValueError('Invalid chart type given %s' % kind)
from pandas import DataFrame
if kind in _dataframe_kinds:
if isinstance(data, DataFrame):
plot_obj = klass(data, x=x, y=y, subplots=subplots, ax=ax,
kind=kind, **kwds)
else:
raise ValueError('Invalid chart type given %s' % kind)Which results in following error message:
C:\Anaconda3\lib\site-packages\pandas\tools\plotting.py in plot_series(series, label, kind, use_index, rot, xticks, yticks, xlim, ylim, ax, style, grid, legend, logx, logy, secondary_y, **kwds)
2231 klass = _plot_klass[kind]
2232 else:
-> 2233 raise ValueError('Invalid chart type given %s' % kind)
2234
2235 """
ValueError: Invalid chart type given hist
I would suggest using the format string "Invalid chart type given: '%s'" instead.
