Angular-google-area-chart 图表背景颜色重叠-解网

问：

我正在使用 .我正在尝试为特定区域显示不同的颜色。但是你可以看到红线和绿线（区域）的区域与蓝色区域重叠。配置有问题吗？angular-google-chart

    },
    'colors': ['#FF0000','#FF0000','#00FF00','#0000FF','#00FF00','#0000FF','#FFFFFF']
},

在我从数组推送数据中：$scope.dataMap

for(var i=0;i<$scope.data.sd0.length;i++){
    $scope.dataMap.push({
        c: [{
            v: $scope.gData.sd0[i].month
        }, {
            v: $scope.gData.sd0[i].value
        }, {
            v: $scope.gData.sd1[i].value
        }, {
            v: $scope.gData.sd2[i].value
        }, {
            v: $scope.gData.sd3[i].value
        }, {
            v: $scope.gData.sd1Neg[i].value
        }, {
            v: $scope.gData.sd2Neg[i].value
        }, {
            v: $scope.gData.sd3Neg[i].value
        }]
    });
}

$scope.gData是我从发布请求中获取的对象，包含值数组。有 7 个值数组，JSON 结构都是一样的

"sd0": [
    {
        "month": "0",
        "value": "2.1"
    },
    {
        "month": "1",
        "value": "2.9"
    },
    {
        "month": "2",
        "value": "3.8"
    },
    {
        "month": "3",
        "value": "4.4"
    }
    .....
]

上一个：当目标元素未溢出时，CSS 'overscroll-behavior： contain'

下一个：CSS 文本省略号，包括“更多”链接
