scatterhist with axis

perfreem@gmail.com — Fri, 30 Jan 2009 15:15:53 -0500

hello,

i am using the scatterhist command to plot a scatter plot along with
its histogram. how can i make it so axes are added to the histogram
(the y axis), so that i know what each bar represents?

thanks you.

Here's one way:

% Get all axes in current figure, make them visible
set(findobj(gcf,'type','axes'),'visib','on')

thanks, but i don't want all the axes to show, just the y axis of the
histograms... how can i find this axis id? i just want to be able to
interpret the height of every bar on the histogram.

one of the solutions

% the data
     x=randn(1000,1);
     y=randn(1000,1);
% the plot
     lh=scatterhist(x,y);
     bc=get(gcf,'color');
     set(lh(2:3),'visible','on','color',bc,'box','off');
% - x-axis hist
     set(lh(2),'xtick',[],'xcolor',bc);
% - y-axis hist
     set(lh(3),'ytick',[],'ycolor',bc);

when i do this, the histogram axes appear to have the right values but
are shown as negative numbers. any idea how to fix this?

thank you

one of the solutions

% the data
     x=5*randn(1000,1);
     y=.5*randn(1000,1);
% the plot
     lh=scatterhist(x,y);
     bc=get(gcf,'color');
     set(lh(2:3),'visible','on','color',bc,'box','off');
% - x-axis hist
     set(lh(2),'xtick',[],'xcolor',bc);
     set(lh(2),'yticklabel',abs(get(lh(2),'ytick')));
% - y-axis hist
     set(lh(3),'ytick',[],'ycolor',bc);
     set(lh(3),'xticklabel',abs(get(lh(3),'xtick')));
