Incubator-echarts: Line增加数据类型

[yangzj208]

What problem does this feature solve?

目前的Line类型的曲线横纵坐标的值必须是一一对应的，很多场合下，横坐标的值一般都是从某一值开始，等间隔分布的，这时如果每一条曲线都按现在的方式存储值的话，在数据量大的时候太浪费空间了。
建议增加一个类型，x值可只保存起始值，间隔值这两个值就可以，具体Y对应的值通过这两个值计算即可
或者有没有其他的方式可实现这一需求，请大家帮忙指教，谢谢

What does the proposed API look like?

series:{
x:{
startvalue:0.1,
interval:0.2
},
y:[0,1.1,3,4,5.6,...]
}

Array(n).fill().map((v, i) => startvalue + i * interval);

谢谢！
请问需要如何配置？
我看示例里都是这样配置的
series: [{
data: [
// 维度X 维度Y 其他维度 ...
[ 3.4, 4.5, 15, 43],
[ 4.2, 2.3, 20, 91],
[ 10.8, 9.5, 30, 18],
[ 7.2, 8.8, 18, 57]
]
}]
各个维度数据必须长度一样

比如你的Y数据是[2, 4, 5, 6, 8, 9, 10, 14, 17, 23, 30]

就可以写成：

let yData = [2, 4, 5, 6, 8, 9, 10, 14, 17, 23, 30];
let startvalue = 1;
let interval = 2;
let data = yData.map((v, i) => [startvalue + i * interval, v])

option = {
    xAxis: {
    },
    yAxis: {
        type: 'value'
    },
    series: [{
        data: data,
        type: 'line'
    }]
};

    },，
    series: [{
        data: data,
        type: 'line'
    }]
};

还可以这样做的，非常感谢，我试试
