Scatter plot the RGB values of an image in 3D! Requires Pillow and matplotlib, running on Python 3.

image_plot.py

image_path = "HOPE.png"

from mpl_toolkits.mplot3d import Axes3D
from matplotlib import pyplot
from PIL import Image

fig = pyplot.figure()
axis = fig.add_subplot(1, 1, 1, projection="3d") # 3D plot with scalar values in each axis

im = Image.open(image_path)
r, g, b = list(im.getdata(0)), list(im.getdata(1)), list(im.getdata(2))

axis.scatter(r, g, b, c="#ff0000", marker="o")
axis.set_xlabel("Red")
axis.set_ylabel("Green")
axis.set_zlabel("Blue")
pyplot.show()

Thank you, it was really helpful for me!

@Uberi small question from me, Ger from the Netherlands.
Is it also possible to get rgb value from plot when i have this script:
crs = new_scn[chan].attrs[‘area’].to_cartopy_crs()
ax = plt.axes(projection=crs)

ax.coastlines()
ax.gridlines()
ax.set_global()
chan_data = new_scn[chan]-273.15 # plot data
im = plt.imshow(chan_data, transform=crs, extent=crs.bounds, origin=‘upper’, cmap=“coolwarm”)
cbar = plt.colorbar()
cbar.set_label(“Kelvin”)

lon = 4.666
lat = 52.496
area = new_scn[chan].attrs[‘area’]
print('lon-lat ',lon, lat)
col, row = area.get_xy_from_lonlat(lon, lat)
print('col-row ',col, row)

global temp
temp = int(new_scn[chan].values[row, col]-273.15) #<-- Here i read the data of the pixel temperature
print('temp-col-row ',temp, col, row)
How can i also get the pixel RGB color value

Thanks in advance for answer
Ger
