04 Jul 2013 digitize Matlab tool for digitizing images Author: Alex Sanchez Bezada, Max

Thank you for this submission. It is, in general, very good, with a few little hiccups. To avoid the 'waitforbuttonpress' error, make sure you stop digitizing (by right-clicking) before you attempt to export the digitized points

25 Apr 2013 scatplot Scatter plot with color indicating data density. Author: Alex Sanchez Guy, Walter

Definition of sub-function range() is missing (no add-on toolboxes), also several missing end statements for sub-functions. Once these errors are corrected it performs well. (R2012a)

20 Jan 2013 scatplot Scatter plot with color indicating data density. Author: Alex Sanchez Grievous, Right

Great piece of code - just what I needed! However, I was wondering if there is anyway to set the colors? i.e. like how you can set a colorbar limits in other matlab plotting tools. I can't seem to find a way.

I have one large density peak which sets the colorbar so high nothing else really shows up...

29 Nov 2012 scatplot Scatter plot with color indicating data density. Author: Alex Sanchez Jose

Very nice job! Very useful.

15 Feb 2011 scatplot Scatter plot with color indicating data density. Author: Alex Sanchez Jin, Hongxiao

%this works fine for simple show
function hh=scatterC(varargin,n,method)
if nargin<2
n = 100; %bins
method='p'%pcolor
end
if nargin<3
method='p'
end

[N C]=hist3(varargin,[n,n]);
N(find(N==0))=NaN;
[X Y]=meshgrid(C{1},C{2});
switch method
case 'p'
pcolor(X,Y,N);shading flat;
case 'c' %contourf
contourf(X,Y,N,'EdgeColor','None');
end
