  echart如何设置饼图的颜色以及柱状图颜色

1.设置饼图颜色

 

var  option = {

                            tooltip: {

                                trigger: \'item\',

                                formatter: "{a} <br/>{b}: {c} ({d}%)"

                            },

                            //设置饼图的颜色

                            color:[\'#f6da22\',\'#bbe2e8\',\'#6cacde\'],

                            legend: {

                                orient: \'vertical\',

                                x: \'left\',

                                data:[\'柴油\',\'汽油\',\'附属油\'],

                                show:false

                            },

                            series: [

                                {

                                    name:\'交易量\',

                                    type:\'pie\',

                                    radius: [\'22%\', \'40%\'],

                                    data:[

                                        {value:35, name:\'柴油35%\'},

                                        {value:20, name:\'汽油20%\'},

                                        {value:45, name:\'附属油45%\'}

                                    ],

                                    label: {

                                        normal: {

                                            textStyle: {

                                                color: \'#333\'

                                            }

                                        }

                                    },

                                    

                                }

                                ]

                            };

 

2.设置柱状图颜色

 

data:[5, 6, 4, 2, 7, 8, 6, 5, 7, 5, 6, 8, 4, 6, 5, 6],

itemStyle:{
       normal:{
         color:\'#32CD32\',
         }
  }
