barhomogenize - homogenize all the bars included in the current working axes
If there are several bar calls, the barhomogenize function allows to homogenize the width and style of all bars (i.e which has the polyline_style type 6) included in the current working axes. These bars must have the same x data.
barhomogenize( ) : takes the default values, h=gca(), width=0.8, style='grouped'.
barhomogenize(h,...) : defines the current axes where the drawing is performed.
barhomogenize(...,width,...) : defines the width of the bar(s) in percentage (generally: 0<width<=1).
barhomogenize(...,style,...) : defines how the bars are drawn. The 'grouped' option allows to center the M polylines versus each components of x, and the 'stacked' option allows to stack them.
// First example: creation of 1 yellow bar (i.e 1 polyline with polyline_style=6) and 3 bars (i.e 3 polylines with polyline_style=6)
subplot(2,3,1)
xtitle('ex1: creation of 1 yellow bar and 3 bars ')
x=1:3; y1=1:3; y2=[4 3 5;6 7 8;9 10 11];
bar(x,y1,'yellow');bar(x,y2);
// grouped homogenisation of these 4 bars
subplot(2,3,2)
xtitle('grouped homogenisation')
x=1:3; y1=1:3; y2=[4 3 5;6 7 8;9 10 11];
bar(x,y1,'yellow');bar(x,y2);
barhomogenize();
// stacked homogenisation of thes 4 bars
subplot(2,3,3)
xtitle('stacked homogenisation')
x=1:3; y1=1:3; y2=[4 3 5;6 7 8;9 10 11];
bar(x,y1,'yellow');bar(x,y2);
barhomogenize('stacked',1);
// Second example : creation of 1 red bar (i.e 1 polyline with polyline_style=6) and 2 polylines with type=1 (calling plot function)
subplot(2,3,4)
xtitle('ex2: creation of 1 bar and 2 polylines')
x=1:10; y=sin(x)/2;
bar(x,y,'red')
x1=1:10;y1=[sin(x);cos(x)]
plot(x1,y1)
// modify the polyline_style type of the second polyline from plot (this polyline becomes a bar)
subplot(2,3,5)
xtitle('transformation of the second polyline to bar')
x=1:10; y=sin(x)/2;
bar(x,y,'red')
x1=1:10;y1=[sin(x);cos(x)]
plot(x1,y1)
e=gce(); e2=e.children(2); e2.polyline_style=6;
// homogenisation of the first bar (from bar function) and second bar (from the modification).
subplot(2,3,6)
xtitle('grouped homogenisation')
x=1:10; y=sin(x)/2;
bar(x,y,'red')
x1=1:10;y1=[sin(x);cos(x)]
plot(x1,y1)
e=gce(); e2=e.children(2); e2.polyline_style=6;
barhomogenize();
// change the style and the width
//barhomogenize('stacked',0.5);
//barhomogenize('stacked',1);
