浮动-显示时间轴没有间隙 [英] flot - show time axis without gaps

问题描述

我正在尝试自定义jQuery Flot以消除时间轴上的点之间的间隙.看上面的图片:

I'm trying to customize jQuery Flot to remove gaps between dots on time axis. Look at the top image:

它显示了两天的数据，我敢打赌你当晚.我要做的是摆脱图表中间的这一令人讨厌的空白.有什么建议怎么做吗?

It shows the data for two days, and I bet you spot the night. What I want to do is to get rid of this annoying gap in the middle of the chart. Any suggestions how to do this?

推荐答案

太糟糕了，我无法接受评论作为答案，因为Mark链接中的George Roberts的答案很正常.

Too bad I can't accept a comment as an answer, since the answer from George Roberts from Mark's link worked smoothly.

因此，我要做的是将float的模式从时间"更改为null，然后模拟时间轴.

So what I had to do is to change the mode of the flot from 'time' to null and then emulate a time axis.

我创建了两个数组:第一个数组包含图形数据，第二个数组包含时间戳:

I've created two arrays: the first one with data for the graph and the second one with timestamps:

for (var i=0; i<json.length; i++ ) {
    dotsData.push( [i, json[i].value] );
    ticks.push( json[i].date );
    }                       
}

时间轴仿真:

// flot options
... xaxis: { tickFormatter: function(val) { return formTicks(val, ticks) } } ...

// formTicks function
function formTicks(val, ticksArr) {
    var tick = ticksArr[val];

    if ( tick != undefined ) {
        tick = new Date( tick );

        var hours = tick.getHours(),
            minutes = tick.getMinutes();

            tick = hours+':'+minutes;
    }
    else { tick = '' }

    return tick
}

它可以解决问题，但很难区分一天，因此我添加了标记:

It solves the problem, but it's hard to distinguish one day from another, so I added markings:

var markings = [],
    firstDay = new Date( ticks[0] ).getDate();

    for (var i=1; i<ticks.length; i++) {
        var loopDay = new Date( ticks[i] ).getDate();
        if ( loopDay != firstDay ) {
            var marking = {
                color: '#000000',
                lineWidth: 1,
                xaxis: { from: i, to: i }
            }

        markings.push( marking )

        firstDay = loopDay; // loop through all days
    }
}

// flot options
grid: { markings: markings }

结果:
