units

units(value, dest='in', axes=None, figure=None, width=True)[source]

Convert values and lists of values between arbitrary physical units. This is used internally all over ProPlot, permitting flexible units for various keyword arguments.

Parameters

  • value (float or str or list thereof) – A size specifier or list thereof. If numeric, nothing is done. If string, it is converted to the units dest. The string should look like '123.456unit', where the number is the magnitude and 'unit' is one of the following.

  • axes (Axes, optional) – The axes to use for scaling units that look like '0.1ax'.

  • figure (Figure, optional) – The figure to use for scaling units that look like '0.1fig'. If None we try to get the figure from axes.figure.

  • width (bool, optional) – Whether to use the width or height for the axes and figure relative coordinates.
