How to Prevent Matplotlib Plots from Using Exponential Notation for Axis Numbers?

Preventing Exponential Notation for Numbers in Matplotlib Plots

When visualizing data using Matplotlib in Python, zooming in on x-axis values may cause them to switch from standard number form to exponential notation. To prevent this and maintain the straightforward numbering of the axis, follow these steps:

1. Disable Scientific Notation:
   Use the set_scientific method of the formatter object to disable scientific notation for all numbers on the x-axis:

<code class="python">ax = plt.gca()
ax.get_xaxis().get_major_formatter().set_scientific(False)</code>

2. Prevent Offset in Tick Labels:
   By default, Matplotlib uses a default formatter (ScalerFormatter) that converts values to scientific notation when zooming in. To avoid this:

<code class="python">ax.get_xaxis().get_major_formatter().set_useOffset(False)</code>

3. Global Control via rcParam:
   To disable scientific notation globally for all axes in future plots, modify the axes.formatter.useoffset parameter in the rcParam settings:

<code class="python">import matplotlib.pyplot as plt
plt.rc('axes', formatter.useoffset=False)</code>

These adjustments ensure that numbers plotted on the x-axis retain their standard form, regardless of zoom level.
