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

scatter_hist.py

Attached is a very simple example that shows how to do something similar to scatterhist in matplotlib Manuel per freem wrote: > 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 > > > >  > >  > Open Source Business Conference (OSBC), March 2425, 2009, San Francisco, CA > OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise > Strategies to boost innovation and cut costs with open source participation > Receive a $600 discount off the registration fee with the source code: SFAD > http://p.sf.net/sfu/XcvMzF8H > > >  > > _______________________________________________ > Matplotlibusers mailing list > Matplotlibusers@... > https://lists.sourceforge.net/lists/listinfo/matplotlibusers

thank you very much for this (i include your code below). one question about this: how can i remove the top xaxis and the right yaxis from each of the marginal histograms? in other words, keep only the left yaxis and the bottom xaxis 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() On Mon, Feb 16, 2009 at 8:22 AM, Manuel Metz <mmetz@...>wrote: > Attached is a very simple example that shows how to do something similar > to scatterhist in matplotlib > > Manuel > > per freem wrote: > > 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 > > > > > > > >  > > > > >  > > Open Source Business Conference (OSBC), March 2425, 2009, San Francisco, > CA > > OSBC tackles the biggest issue in open source: Open Sourcing the > Enterprise > > Strategies to boost innovation and cut costs with open source > participation > > Receive a $600 discount off the registration fee with the source code: > SFAD > > http://p.sf.net/sfu/XcvMzF8H > > > > > >  > > > > _______________________________________________ > > Matplotlibusers mailing list > > Matplotlibusers@... > > https://lists.sourceforge.net/lists/listinfo/matplotlibusers > > > > >  > Open Source Business Conference (OSBC), March 2425, 2009, San Francisco, > CA > OSBC tackles the biggest issue in open source: Open Sourcing the > Enterprise > Strategies to boost innovation and cut costs with open source > participation > Receive a $600 discount off the registration fee with the source code: > SFAD > http://p.sf.net/sfu/XcvMzF8H > _______________________________________________ > Matplotlibusers mailing list > Matplotlibusers@... > https://lists.sourceforge.net/lists/listinfo/matplotlibusers > >
