X轴上的分割线splitLine属性interval formatter函数控制显示错误

[junHaiBuilder-one]

One-line summary [问题简述]

直角坐标系下的X轴上的分割线splitLine属性interval使用formatter函数进行控制分割线显示不正确。

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]: ECharts 4.10
• Browser version [浏览器类型和版本]: chrome 版本 69.0.3497.100（正式版本） （32 位）
• OS Version [操作系统类型和版本]: window 7

Expected behaviour [期望结果]

通过splitLine的进行上下双X轴的分组显示，如上X轴可以作为类目分组（如：地区），下X轴作为具体类目（如：省份），通过splitLine进行严格的分割线隔离。
预期分割线的formatter函数能够严格控制分割线的显示

ECharts option [ECharts配置项]

option = {
    xAxis: {
        type: 'category',
        splitLine:{
            show:true,
            // interval: 3
            interval: function(params, name){
                if(params == 0 || params == 6){
                    return true;
                }
                return false;
            }
        },
         axisTick:{
            show:true,
            interval: function(params, name){
               
                if(params == 4 || params == 5){
                    return true;
                }
                return false;
            }
        },
        data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
    },
    yAxis: {
        type: 'value'
    },
    series: [{
        data: [120, 200, 150, 80, 70, 110, 130],
        type: 'bar'
    }]
};

interval 支持函数形式可能技术层面不太好实现
