itemStyle: { 
normal:{ 
color: function (params){
var colorList = ['rgb(205,85,85)','rgb(210,105,30)','rgb(0,139,0)','rgb(178,58,238)','rgb(54,100,139)'];
return colorList[params.dataIndex];

//鼠标悬停时：
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'

//end
}
]

myChart.setOption(option);
