Примерно так:
var hbar = new RGraph.SVG.HBar({
id: 'cc',
data: [[2,3],[1,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0]],

yaxisLabels: ['Abc','Def','Ghi','Jkl','Mno','Pqr','Stu','Vwx','Yz','nuj'],
xaxis: false,
yaxis: false,
colors: ['yellow','green'],
gutterLeft: 50,
gutterLeftAutosize: false,
gutterRight: 75
}
}).grow();
// Add the text that gives the percentages
for (var i=0; i<hbar.coords.length; ++i) {
var value = hbar.coords[i].element.getAttribute('data-value'),
y = (i % 2 === 0) ? hbar.coords[i].y + hbar.coords[i].height + 5 : y,
x = (i % 2 === 0) ? hbar.width - hbar.properties.gutterRight + 10 : x + 35;
RGraph.SVG.text({
object: hbar,
text: value + '%',
x: x,
y: y,
color: 'black',
halign: 'left',
valign: 'center',
size: 12
});
