I am having an issue with the format of the tick labels of an axis. I disabled the offset from the y_axis:
ax1.ticklabel_format(style = \'sci\', useOffset=Fa
You should also specify axis and threshold limits:
ax1.ticklabel_format(axis='y', style='sci', scilimits=(-2,2))
This would use sci format on y axis when figures are out of the [0.01, 99] bounds.
[0.01, 99]
