- spacepy.plot.add_logo(img, fig=None, pos='br', margin=0.05)¶
Add an image (logo) to one corner of a plot.
The provided image will be placed in a corner of the plot and sized to maintain its aspect ratio and be as large as possible without overlapping any existing elements of the figure. Thus this should be the last call in constructing a figure.
- imgstr or numpy.ndarray
The image to place on the figure. If a string, assumed to be a filename to be read with
imread(); if a numpy array, assumed to be the image itself (in a simliar format).
- Other Parameters:
The figure on which to place the logo; if not specified, the
gcf()function will be used.
The position to place the logo. br: bottom right; bl: bottom left; tl: top left; tr: top right
Margin to include on each side of figure, as a fraction of the larger dimension of the figure (width or height). Default is 0.05 (5%).
