# barhomogenize

homogenize all the bars included in the current working axes

## Calling Sequence

    barhomogenize()
                barhomogenize([h[,'style'[,'width']]])

## Arguments

h

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

style

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

width

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

## Description

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.

## Examples

    // 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 homogenization of these 4 bars
    subplot(2,3,2)
    xtitle('grouped homogenization')
    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 homogenization of the 4 bars
    subplot(2,3,3)
    xtitle('stacked homogenization')
    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);

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);

subplot(2,3,2) xtitle('grouped homogenization') x=1:3; y1=1:3; y2=[4 3 5;6 7 8;9 10 11]; bar(x,y1,'yellow');bar(x,y2); barhomogenize();

subplot(2,3,3) xtitle('stacked homogenization') 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;

    // homogenization of the first bar (from bar function) and second bar (from the modification).
    subplot(2,3,6)
    xtitle('grouped homogenization')
    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);

// 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;
