hist3d

3D representation of a histogram

Syntax

hist3d(mtx)
hist3d(mtx, theta)
hist3d(mtx, theta, alpha)
hist3d(mtx, theta, alpha, leg)
hist3d(mtx, theta, alpha, leg, flag)
hist3d(mtx, theta, alpha, leg, flag, ebox)

hist3d(mtx, <opt_args>)

hist3d(list(mtx,x,y), …)

Arguments

mtx

matrix of size (m,n) defining the histogram mtx(i,j)=F(x(i),y(j)), where x and y are taken as 0:m and 0:n.

list(mtx,x,y)

where mtx is a matrix of size (m,n) defining the histogram mtx(i,j)=F(x(i),y(j)), with x and y vectors of size (1,m+1) and (1,n+1).

theta, alpha, leg, flag, ebox

see plot3d.

<opt_args>

This represents a sequence of statements key1=value1, key2=value2,... where key1, key2,... can be one of the following: theta, alpha, leg, flag, ebox. See plot3d.

Description

hist3d represents a 2d histogram as a 3D plot. The values are associated to the intervals [x(i), x(i+1)[ × [y(i), y(i+1)[.

Examples

hist3d()

hist3d(grand(10, 10, "nor", 0, 10))

Z = zeros(100,5);
A = abs(rand(40,5));
Z(1:40,:) = A;
scf();
hist3d(Z);
isoview off

Z = zeros(100,5);
A = abs(rand(40,5));
Z(1:40,:) = A;
Index = find(Z==0);
Z(Index) = %nan;
scf();
hist3d(Z);
isoview off

Z = zeros(100,5);
A = abs(rand(40,5));
Z(1:40,:) = A;
A = abs(rand(10,5));
Z(91:100,:) = A;
scf();
hist3d(Z);
isoview off
