RGraph，不工作

Question

我想上色条形图栏的颜色，但除了Key获取OK，所有的酒吧显相同颜色的

window.onload = function() 
{ 
    var bar = new RGraph.Bar('canv1', [20,17,13,7,5,1,1,1,1,1,1,1,1,1,1]) 
     .Set('labels', ['M1','M2','M3','M4','M5','M6','M7','M8','M9','M10','M11','M12','M13','M14','M15']) 
     .Set('grouping', 'stacked') 
     .Set('gutter.bottom', 250) 
     .Set('gutter.left', 100) 
     .Set('gutter.top', 20) 
     .Set('gutter.right', 100) 
     .Set('text.angle', 70) 
     .Set('labels.above', true) 
     .Set('labels.above.size', 8) 
     .Set('ymax', 20) 
     .Set('shadow', false) 
     .Set('background.grid.autofit.numhlines', 2) 
     .Set('numxticks', 15) 
     .Set('background.grid.autofit.numvlines', 15) 
     .Set('numyticks', 2) 
     .Set('ylabels.count', 2) 
     .Set('key', ['M1','M2','M3','M4','M5','M6','M7','M8','M9','M10','M11','M12','M13','M14','M15']) 
     .Set('colors', ['#0099FF','#006699','#006699','#006699','#006699','#6699FF','#6699FF','#6699FF','#6699FF','#006699','#006699','#006699','#006699','#006699','#006699']) 
     .Set('scale.decimals', 0) 
     .Draw(); 
} 

有人可以帮助我，好吗？

尝试增加：

bar.Set('colors.sequential', true);
