How to Stop Matplotlib from Using Scientific Notation?

How to Avoid Scientific Notation in Matplotlib

When plotting data, you may encounter scientific notation, where numbers are expressed as a coefficient multiplied by a power of 10. To prevent scientific notation, it's essential to distinguish between two aspects of axis formatting: "offset" and "scientific notation."

Difference between Offset and Scientific Notation

• Offset: An additive constant that shifts the values shown on the axis. It is typically represented by a " " sign, as in "5e 06".
• Scientific Notation: A multiplicative factor that scales the values shown on the axis. It is typically represented by a power of 10, as in "5 x 10^6".

Disabling Offset or Scientific Notation

To disable the offset, use ax.ticklabel_format(useOffset=False). To disable scientific notation, use ax.ticklabel_format(style='plain').

Example

For instance, in the following code:

plt.plot(range(2003,2012,1),range(200300,201200,100))
ax.ticklabel_format(useOffset=False)
plt.show()

The useOffset=False argument disables the offset on the x-axis, leaving the y-axis scientific notation intact.

Disabling Both Offset and Scientific Notation

To disable both offset and scientific notation, combine both arguments:

ax.ticklabel_format(useOffset=False,>

This will result in numbers being displayed without any offsets or scientific notation.

Additional Notes

• If the ticklabel_format method doesn't work, try setting the axis limits manually: plt.xlim(xmin, xmax) and plt.ylim(ymin, ymax).
• For more control, consider using the matplotlib.ticker module to customize the axis formatting.
