python - Plotting a Pandas DataSeries.GroupBy

Question

I am new to python and pandas, and have the following DataFrame.

How can I plot the DataFrame where each ModelID is a separate plot, saledate is the x-axis and MeanToDate is the y-axis?

Attempt

data[40:76].groupby('ModelID').plot()

DataFrame

Answer 1

You can make the plots by looping over the groups from groupby:

import matplotlib.pyplot as plt

for title, group in df.groupby('ModelID'):
    group.plot(x='saleDate', y='MeanToDate', title=title)

See for more information on plotting with pandas dataframes:
