Negative line calculate stack

[mexvod]

option = {

grid: {
    left: '3%',
    right: '4%',
    bottom: '3%',
    containLabel: true
},
xAxis : [
    {
        type : 'category',
        boundaryGap : false,
        data : [1,2,3,4,5]
    }
],
yAxis : [
    {
        type : 'value'
    }
],
series : [
    {
        type:'line',
        stack: '1',
        data:[110,120, 120, 101,115]
    },
    {
        type:'line',
        stack: '1',
        label: {
            normal: {
                show: true,
                position: 'top'
            }
        },
        areaStyle: {normal: {}},
        data:[134,200, -20, 181,143]
    }
]

};

Negative areaStyle badly !!
Next:
option = {

grid: {
    left: '3%',
    right: '4%',
    bottom: '3%',
    containLabel: true
},
xAxis : [
    {
        type : 'category',
        boundaryGap : false,
        data : [1,2,3,4,5]
    }
],
yAxis : [
    {
        type : 'value'
    }
],
series : [
    {
        type:'line',
       
        data:[110,120, 120, 101,115]
    },
    {
        type:'line',
       
        label: {
            normal: {
                show: true,
                position: 'top'
            }
        },
        data:[134,200, 80, 181,143]
    }
]

};

How to make:

how to paint over these areas?

An option to disable negative stacks would result in the image with black painting. Example:

Notice that negative stack is also causing distorted areas such as that in #9317, and areas are drawn correctly with it disabled. Ideally, in a stacked chart with negative stack, the line would break where the function's interpolated value becomes 0, and jump immediately between positive and negative parts of the chart:
