For example you can plot an image in matplotlib using this code:
%matplotlib inline
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
img=mpimg.imread('image.png')
plt.imshow(img)
Is something like this possible with Bokeh(0.10)?
You can use the ImageURL
glyph (image_url
plot method)to load images locally or from the web.
from bokeh.plotting import figure, show, output_file
output_file('image.html')
p = figure(x_range=(0,1), y_range=(0,1))
p.image_url(url=['tree.png'], x=0, y=1, w=0.8, h=0.6)
## could also leave out keywords
# p.image_url(['tree.png'], 0, 1, 0.8, h=0.6)
show(p)
One gotcha - if you graph only an image (and no other data), you'll have to explicitly set the plot ranges.
Here's the docs:
