pandas (original) (raw)

Because hist and boxplot are separated from normal plot, there are some inconsistencies with these functions. Looks better to include them to MPLPlot framework.

Maybe scatter and hist can be deprecated in 0.15 if MPLPlot can offer better GroupBy plot (plan to do in separate PR).

Example

This allows to use kind='hist in DataFrame.plot and Series.plot. (No changes for DataFrame.hist)

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

df = pd.DataFrame(np.random.randn(1000, 5))
df.plot(kind='hist', subplots=True)

df.plot(kind='hist', stacked=True)

Remaining Items

Add a release note in API section detailing this change/enhancement
Modify doc

- Add support for rot and fontsize (depending on orientation kw) (rely on BUG/VIS: rot and fontsize are not applied to timeseries plots #7844)
- Add tests for xticklabels and yticklabels
- Add tests for colors
- Handling nan
Check stacked=True can be supported (DataFrame.hist doesn't support it though..).
