Here is a simple example of a line plot, using the matplotlib library.

import matplotlib.pyplot as plt
import pandas as pd

# We create our dataframe
df = pd.DataFrame(index=range(0,10), data={"col1" : range(0,10)})

fig, axes = plt.subplots(1,1, figsize=(8,6))

# We do a line plot on the axes
axes.plot(df.index, df["col1"])

# Fixing the layout to fit the size
fig.tight_layout()

# Showing the plot
plt.show()

Changing the axis labels

We can change the labels and the axis values themselves.

In order to change the axis labels we use the axes.set_xlabel() and axes.set_ylabel() methods as in the following example.

import matplotlib.pyplot as plt
import pandas as pd

# We create our dataframe
df = pd.DataFrame(index=range(0,10), data={"col1" : range(0,10)})

# We setup our subplots graph on which we are going
# to plot.
fig, axes = plt.subplots(1,1, figsize=(8,6))

# We do a line plot on the axes
axes.plot(df.index, df["col1"])

# We change the labels on the different axis.
axes.set_xlabel("X axis")
axes.set_ylabel("Y axis")

# Fixing the layout to fit the size
fig.tight_layout()

# Showing the plot
plt.show()
