One way to use images as a marker would be to use offsetbox module. Here is an example adopted from
http://matplotlib.sourceforge.net/examples/pylab_examples/demo_annotation_box.html Regards, -JJ import matplotlib.pyplot as plt from matplotlib.offsetbox import OffsetImage, AnnotationBbox from matplotlib.cbook import get_sample_data import numpy as np if 1: fig = plt.gcf() fig.clf() ax = plt.subplot(111) xy = [0.3, 0.55] arr = np.arange(100).reshape((10,10)) im = OffsetImage(arr, zoom=2) ab = AnnotationBbox(im, xy, xycoords='data', pad=0.3, ) ax.add_artist(ab) # another image from matplotlib._png import read_png fn = get_sample_data("lena.png", asfileobj=False) arr_lena = read_png(fn) imagebox = OffsetImage(arr_lena, zoom=0.1) xy = (0.7, 0.4) ab = AnnotationBbox(imagebox, xy, xycoords='data', pad=0.5, ) ax.add_artist(ab) ax.set_xlim(0, 1) ax.set_ylim(0, 1) plt.draw() plt.show() On Thu, Mar 8, 2012 at 4:25 AM, Michael Droettboom <md...@stsci.edu> wrote: > It would be a nice idea.
