在 pandas.DataFrame.plot 中添加 X 轴标签

Question

I have a dataframe that contains a column c of ones and zeros. I want to plot the histogram for this column. I tried the following:

    df.c.plot(kind='hist', weights = np.ones_like(df.index)/ len(df.index), title='Percentage', grid=True)

The result is a plot with two bars; one for the zero value and one for the one value. How to add labels for these two bars, say on the x-axis? Instead of using weights , is there another way to present the percentage values?
