Description:
 def _scale_translate(fig, scale_x, scale_y, translate_x, translate_y):
 """ Scale a figure and translate it to sub-region of the original figure canvas. Note: If the input figure has a title, this title is converted into an annotation and scaled along with the rest of the figure. Note: This function mutates the input fig dict Note: This function assumes that the normalize_subplot_ids function has already been run on the figure, so that all layout subplot properties in use are explicitly present in the figure's layout. Parameters fig: dict A plotly figure dict scale_x: float Factor by which to scale the figure in the x-direction. This will typically be a value < 1. E.g. a value of 0.5 will cause the resulting figure to be half as wide as the original. scale_y: float Factor by which to scale the figure in the y-direction. This will typically be a value < 1 translate_x: float Factor by which to translate the scaled figure in the x-direction in normalized coordinates. translate_y: float Factor by which to translate the scaled figure in the x-direction in normalized coordinates.
