#1 Created at ... [Delete] [Delete and Lock User]

哎╮(╯▽╰)╭，不知道K线对不对，大概能显示个变化吧。 var path=new Path2D(); var path2=new Path2D(); var x = 10; for(var i = 0;i<data.length;i++){ console.log(data[i].low); x = x + 8; path.lineTo(x, 100-data[i].high/50); path2.lineTo(x, 100-data[i].low/50); } ctx.strokeStyle = '#0000ff'; ctx.stroke(path); ctx.strokeStyle = '#000000'; ctx.stroke(path2);

程序猿dwSun

#2 Created at ... [Delete] [Delete and Lock User] 
var x = 10;
var ps={};
ps.p1=new Path2D();
ps.p2=new Path2D();

data.unshift(ps)
data.reduce(function(paths,data){
    console.log(data);
    x = x + 8;
    ps.p1.lineTo(x, 100-data.high/100);
    ps.p2.lineTo(x, 200-data.low/100);
    return ps;
});

ctx.strokeStyle = '#00f0ff';
ctx.stroke(ps.p2);
ctx.strokeStyle = '#0000ff';

ctx.stroke(ps.p1);

想到了一个这种的用法
