如何在自定义线中绘制自定义线和隐藏线？

Question

我收到一个请求，他们希望每个数据的两个值成为一行。 其余的值和往常一样。

这些是我现在拥有的代码。

javascript

new Dygraph(
    document.getElementById("bp_chart"),
    "restful/char/bp/#{memberInfo.selectedContract.member.id}",
    {labels: ['Date', '#{msg['measure.BP.SBP']}', '#{msg['measure.BP.DBP']}', '#{msg['measure.BP.pulse']}', "#{msg['measure.BP.SBPover']}", "#{msg['measure.BP.DBPover']}", "#{msg['measure.BP.pulseover']}"],
    showRangeSelector: true,
    '#{msg['measure.BP.SBPover']}': {
        strokeWidth: 0.0,
        drawPoints: true,
        pointSize: 2,
        color: 'red'
    }, '#{msg['measure.BP.DBPover']}': {
        strokeWidth: 0.0,
        drawPoints: true,
        pointSize: 2,
        color: 'red'
    }, '#{msg['measure.BP.pulseover']}': {
        strokeWidth: 0.0,
        drawPoints: true,
        pointSize: 2,
        color: 'red'
    }
});

外观如何（不允许我嵌入图片，请点击链接查看）

每个数据的两个值合为一行（红点仍应保留）

隐藏两个值的原始行（这就是他们想要的）

是否可以通过数据值绘制自定义线并隐藏一些线？
