custom类别的图形 双Y轴位置异常

[EzioReturner]

One-line summary [问题简述]

当使用 type 为 'custom' 类别的图形时，
使用了双Y轴，同时series下有两个custom系列存在的情况下 第两个Y轴会重叠，且无法设置位置

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]: v 4.0
• Browser version [浏览器类型和版本]: chrome
• OS Version [操作系统类型和版本]: mac

Expected behaviour [期望结果]

双Y轴一左一右显示

ECharts option [ECharts配置项]

var data = [[10, 16, 3, 'A'], [16, 18, 15, 'B'], [18, 26, 12, 'C'], [26, 32, 22, 'D'], [32, 56, 7, 'E'], [56, 62, 17, 'F']];

你自己检查一下哪里写错了吧，下面的代码可以实现自定义系列双 Y 轴：

var data = [[10, 16, 3, 'A'], [16, 18, 15, 'B'], [18, 26, 12, 'C'], [26, 32, 22, 'D'], [32, 56, 7, 'E'], [56, 62, 17, 'F']];
var colorList = ['#4f81bd', '#c0504d', '#9bbb59', '#604a7b', '#948a54', '#e46c0b'];

data = echarts.util.map(data, function (item, index) {
    return {
        value: item,
        itemStyle: {
            normal: {
                color: colorList[index]
            }
        }
    };
});

function renderItem(params, api) {
    var yValue = api.value(2);
    var start = api.coord([api.value(0), yValue]);
    var size = api.size([api.value(1) - api.value(0), yValue]);
    var style = api.style();

    return {
        type: 'rect',
        shape: {
            x: start[0],
            y: start[1],
            width: size[0],
            height: size[1]
        },
        style: style
    };
}

option = {
    title: {
        text: 'Profit',
        left: 'center'
    },
    tooltip: {
    },
    xAxis: {
        scale: true
    },
    yAxis: [{
        name: '1'
    }, {
        name: '2'
    }],
    series: [{
        type: 'custom',

        },
        dimensions: ['from', 'to', 'profit'],
        encode: {
            x: [0, 1],
            y: 2,
            tooltip: [0, 1, 2],
            itemName: 3
        },
        data: data
    }, {
        type: 'custom',
        renderItem: renderItem,
        yAxisIndex: 1,
        label: {
            normal: {
                show: true,
                position: 'top'
            }
        },
        dimensions: ['from', 'to', 'profit'],
        encode: {
            x: [0, 1],
            y: 2,
