plotting in pandas is not picking the list of colors passed, it only gets the first value · Issue #16822 · pandas-dev/pandas (original) (raw)

Code Sample, a copy-pastable example if possible

df = pd.DataFrame({"A": range(4), "color": ['red', 'blue', 'blue', 'red']}) ax = df.plot.bar(y='A', color=df['color']) [p.get_facecolor() for p in ax.patches] [(1.0, 0.0, 0.0, 1.0), (1.0, 0.0, 0.0, 1.0), (1.0, 0.0, 0.0, 1.0), (1.0, 0.0, 0.0, 1.0)]

Problem description

It plots correctly but it does not pick the right color per bar. it only pick the color of the first value in the list.
it was working perfectly in pandas 0.19.2

Expected Output

the plot should contain a different color as the list is being passed. Similar to matplotlib behavior and the old pandas version
