thank you very much for this (i include your code below).

one question about this: how can i remove the top x-axis and the right yaxis from each of the marginal histograms? in other words, keep only the left y-axis and the bottom x-axis of each of the histograms.

thank you.

mport numpy as np

import matplotlib.pyplot as plt

from matplotlib.ticker import NullFormatter

x = np.random.randn(1000)

y = np.random.randn(1000)

nullfmt = NullFormatter() # no labels

left, width = 0.1, 0.65

bottom, height = 0.1, 0.65

bottom_h = left_h = left+width+0.02

rect1 = [left, bottom, width, height]

rect2 = [left, bottom_h, width, 0.2]

rect3 = [left_h, bottom, 0.2, height]

# start with a rectangular figure

#fig = plt.Figure( (8,8) )

axScatter = plt.axes(rect1)

axHistx = plt.axes(rect2)#, sharex=axScatter)

axHisty = plt.axes(rect3)#, sharey=axScatter)

axHistx.xaxis.set_major_formatter(nullfmt)

axHisty.yaxis.set_major_formatter(nullfmt)

axScatter.scatter(x,y)

bins = np.linspace(-4,4,21)

axHistx.hist(x, bins=bins)

axHisty.hist(x, bins=bins, orientation=‘horizontal’)

axHistx.set_xlim( axScatter.get_xlim() )

axHisty.set_ylim( axScatter.get_ylim() )

plt.show()

Attached is a very simple example that shows how to do something similar

to scatterhist in matplotlib

hello,

is there a way to make a 2d scatter plot that includes (outside the axes)

histograms of the marginals of the two variables? like the matlab function

‘scatterhist’. see this for an example:

http://www.mathworks.com/access/helpdesk/help/toolbox/stats/index.html?/access/helpdesk/help/toolbox/stats/scatterhist.html

ideally i’d like the histograms outside the scatter plot to also have axes

so that the height of each histogram bar will be interpretable.

i understand that there’s no command for this - but how can i construct it?

i would not mind writing code to do this… if it’s possible. right now

this is the only thing keeping me from switching from matlab to matplotlib

exclusively since i use these graphs a lot

thank you
