PlotLabeller Context Manager

The purpose of PlotLabeller is to assist with setting tick label locators and formatters consistently for multiple plots. This helps to ensure that your plots maintain a common formatting look and, in conjunction with the TexEngFormatter class, that axes tick labels do not have excessive digits for large or small numbers.

In its simplest form, PlotLabeller will simply apply the TexEngFormatter tick label formatter to all the axes of any plots created within the context manager. If the minor tick formatter is set to NullFormatter, this is respected and the minor tick labels are left unset.

You can pass optional parameters x, y and z to the PlotLabeller which contain either:

• A subclass of matplotlib.ticker.Formatter or matplotlib.ticker.Locator

• An instance of either matplotlib.ticker.Formatter or matplotlib.ticker.Locator

• A list or tuple of either of the above. This allows both a locator and a formatter to be specified for the corresponding axes within one PlotLabeller context manager.

To use PlotLabeller, you would typically just stack it with SavedFigure:

with (SavedFigure(figures / "fig01c.png", style=["stoner"], autoclose=__name__ != "__main__"),
      PlotLabeller()):
    fig, ax = plt.subplots()
    for p in [10, 15, 20, 30, 50, 100]:
        ax.plot(x * 1E5, model(x, p) * 1E-6, label=p, marker="")
    ax.legend(title="Order")
    ax.autoscale(tight=True)
    ax.set(**pparam)

This will give a plot somewhat like:
