Set the text values of the tick labels.
Discouraged
The use of this method is discouraged, because of the dependency on tick positions. In most cases, you'll want to use set_[x/y]ticks(positions, labels) instead.
If you are using this method, you should always fix the tick positions before, e.g. by using Axis.set_ticks or by explicitly setting a FixedLocator. Otherwise, ticks are free to move and the labels may end up in unexpected positions.
Texts
Texts for labeling each tick location in the sequence set by Axis.set_ticks; the number of labels must match the number of locations.
If True, set minor ticks instead of major ticks.
Text properties.
TextsFor each tick, includes tick.label1 if it is visible, then tick.label2 if it is visible, in that order.
