Plot dataframe columns against each other

Solution 1:

As far as I remember plot uses the index for the x values. Try:

df.set_index('CET').plot()

And you should make sure that all you columns have a numeric datatype.

Edit:

df = df.set_index('CET')
num_cols = ['MaxTemp',
            'MeanTemp',
            'MinTemp',
            'MaxHumidity',
            'MeanHumidity',
            'MinHumidity',
            'revenue']
df[num_cols] = df[num_cols].astype(float)
df[num_cols].plot()
plt.xticks(range(len(df.index)), df.index)

Solution 2:

The pandas plotting routines like plot.line or plot.scatter can take the column names for x and y arguments:

E.g.

>>> lines = df.plot.line(x='pig', y='horse')

>>> ax1 = df.plot.scatter(x='length',
...                       y='width',
...                       c='DarkBlue')
