barh

horizontal display of bar histogram

Syntax

barh(y)
barh(x,y)
barh([h],x,y [,width [,color [,style]]])

Arguments

h

an axes handle, (default: h=gca() ).

y

a real scalar, vector of size N, or a matrix N*M.

x

a real scalar or a vector of size N, (default: if y is a vector then x is a vector and x length equals to y length. If y is a matrix then x is a vector and x length equals to the lines number of y.

width

(optional), a real scalar, defines the width (a percentage of the available room) for the bar (default: 0.8, i.e=80%).

color

(optional), a string (default: 'blue'), specifying the inside color bar.

style:

a string, 'grouped' or 'stacked' (default: 'grouped').

Description

barh(y,...) : if y is a vector then bar function draws a polyline which has the polyline_style type 6. If y is a vector, bar draws vector y versus vector x=1:size(y,'*') . If y is a matrix N*M, bar draws M polylines (type 6), each polyline corresponds to a column of y versus vector x=1:size(y,1).

barh(x,y,...) : if y is a vector then bar function draws a polyline which has the polyline_style type 6, where x length = y length. If y is a matrix NxM then bar function draws M polylines which have the type 6. Each polyline corresponds to a column of y versus vector x.

barh(h,...) : defines the current axes where the drawing is performed.

barh(...,width,...) : defines the width of the bar(s) in percentage (generally: 0<width<1).

barh(...,style,...) : defines how the bar is drawn. If y is a matrix N*M (so M polylines of type 6) then there are two ways to draw the M bars. the style option = 'grouped' allows to center the M polylines versus each components of x, and the style option = 'stacked' allows to stack them.

barh(...,color,...) :defines the bar color. Bar functions uses the same colormap than in the plot function.

If there are several bar calls, the barhomogenize function allows to homogenize the width and style of all bars (i.e polylines of type 6) included in the current working axes.

Examples

// First example: draw a bar (i.e a polyline with polyline_style type =6),default style='grouped', width=0.5, color='yellow', default x=1:length(y)
scf(0);
y=[1 -3 5];
barh(y,0.5,'yellow');
// Second example: draw 3 bars (i.e 3 polylines with polyline_style type =6),default style='grouped'
scf(1);
x=[1 2 5];
y=[1  -5 6;3 -2 7;4  -3 8];
barh(x,y);
// Third example : style='stacked'.
scf(2);
x=[1 2 5];
y=[1 4 7;2 5 8;3 6  9];
barh(x,y,'stacked');
// Fourth example: width=0.2;color='green'; default style='grouped'
scf(3);
x=[1 2 5];
y=[1 4 7;2 5 8;3 6 9];
barh(x,y,0.2,'green');
