PolarTranslate

class pysmithchart.polar_transform.PolarTranslate(axes, pad, font_size, *args, **kwargs)

Bases: BasePolarTransform

Transformation for translating points radially outward from the center of the Smith chart.

This transformation moves points away from the center of the Smith chart (typically at [0.5, 0.5] in axis coordinates) by a specified padding distance. The y-coordinate translation includes an additional adjustment based on the font size.

Methods Summary

inverted()	Return the inverse transformation.
transform_non_affine(values)	Apply the non-affine polar translation transformation.

Methods Documentation

inverted()

Return the inverse transformation.

The inverse transformation moves points radially inward toward the center of the Smith chart, reversing the effect of the outward translation applied by this transformation.

Returns:

PolarTranslateInverse – An instance of the inverse transformation.

transform_non_affine(values)

Apply the non-affine polar translation transformation.

This method translates points radially outward from the center of the Smith chart by a specified padding distance. For the y-axis, an additional shift proportional to the font size is applied.

The center of the Smith chart is assumed to be at [0.5, 0.5] in axis coordinates. For the y-coordinate, the translation is pad + 0.5 * font_size.

Parameters:

values (array-like) – A single point (x, y) or a list of points to transform.

Returns:

list or tuple – The transformed points, translated outward from the center.
