Dealing with Axis Offsets for Whole Numbers in Matplotlib

In creating matplotlib figures, you may encounter issues with axis offsets displaying as decimals. For instance, nanosecond measurements show as 4.4e-8 instead of 44e-9 on the y-axis, and day counts appear as 5.54478e4 instead of 55447 on the x-axis.

To resolve this, you can disable offsets for specific axes using a ScalarFormatter with useOffset=False. Here's how:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

# Disable offset for y-axis
y_formatter = ScalarFormatter(useOffset=False)
ax.yaxis.set_major_formatter(y_formatter)

For the x-axis, you can use:

# Disable offset for x-axis
x_formatter = ScalarFormatter(useOffset=False)
ax.xaxis.set_major_formatter(x_formatter)

With these changes, the axes will display whole numbers for the offsets, as desired.
