Matplotlib Resize Image

Question

I have a Python geoprocessing tool that creates a chart from a click on our website. I'm trying to put our company's logo in the chart, but it's a little too big and it's blocking some of the X axis labels. I've tried physically resizing the .png in Windows and linking to the smaller version. No matter which one I use, it's displayed the same size in the chart. I haven't been able to find a clear solution online. Here is my code: fig, ax1 = plt.subplots(figsize=(12,8),facecolor='w') logo = plt.imread(get_sample_data("our logo")) axim = fig.add_axes([0.01,0.01,0.2,0.14], anchor='SW') axim.imshow(logo, aspect='auto') axim.axis('off') ‍‍‍‍‍‍

Yeah its not something I've used often, just saw the snippet in the docs and figured it was a different approach worth trying.

I also just found this tutorial which looks better than the PIL approach, uses OffsetImage and AnnotationBox:

pylab_examples example code: demo_annotation_box.py — Matplotlib 2.0.2 documentation

I tried this and nothing showed up. I've always had problems with PIL.

In the matplotlib docs there are some examples using PIL (Python Image Library) to resize the image before plotting:

In [16]: from PIL import Image
In [17]: img = Image.open('../_static/stinkbug.png')
In [18]: img.thumbnail((64, 64), Image.ANTIALIAS) # resizes image in-place
In [19]: imgplot = plt.imshow(img)

Perhaps give that a try?
