Hi everyone, I have been using code similar to the below to

The call to semilogx calls ax.set_xscale which overrides your custom
formatter. The following should work
ax.semilogx(x_axis, fp_y_axis, 'r', linewidth=0.1, markersize=2, label = "False Positive")
formatter = FuncFormatter(log10Product)
Ie, set your formatter after any call to set_xscale or semilogx.
