        "\n# Setting tick labels from a list of values\n\nUsing `.Axes.set_xticks` causes the tick labels to be set on the currently\nchosen ticks. However, you may want to allow matplotlib to dynamically\nchoose the number of ticks and their spacing.\n\nIn this case it may be better to determine the tick label from the\nvalue at the tick. The following example shows how to do this.\n\nNB: The `.ticker.MaxNLocator` is used here to ensure that the tick values\ntake integer values.\n"
