我正在绘制一些存储在骨干集合中的指标,这些指标每秒都会更新。我没有看到在立体主义上绘制的正确指标。对于每个指标,我只得到一个绘制的指标(带有不正确的)值。我真的不知道如何调试它。这是我的代码:

           var models = dataSet.models;

        //aggregate 'metrics'. Each component has a 'metric' which contains its stats over time
        for(model in models){
            var attributes = models[model].attributes;
            var metricData = metricCache.get(models[model].id);
            var metrics = metricData['attributes']['metrics'];

            if(!attributes['name'] || attributes['type']== "FLOW" || attributes['type'] == "SERVER"){
                continue;
            }
            if(attributes['name'] == null){
                continue;
            }
            var name = attributes['name'];
            var type = attributes['type'];
            var metName = name;

            /* GETTING METRIC. Using js closure to pass correct values to metric call */
            if(metricData != null){
                //var curContext = getMetric(metName, metrics);
                var curContext = (function(val1, val2){
                    return getMetric(val1, val2);
                })(metName,metrics);
            }

            statsList.push(curContext);

        }

'getMetric' 采用指标的名称和 'metrics',这是一个对象数组,其中每个对象都有一个时间戳和一个值。我只是试图在水平图表上绘制每个值及其相应的时间戳。这是我的“getMetric”代码。

            function getMetric(name, metricData){
            var format = d3.time.format("%I-%M-%S");
            return context.metric(function(start, stop, step, callback){
                var statValues = [];

                    var lookup = {},
                    i = start.getTime();
                    //console.log('startTime', i);
                    var curStat = null;
                    for(stat in metricData){
                        curStat = metricData[stat];
                        curStat.value = +curStat.value;
                        var curDate = new Date(curStat.timestamp);
                        curDate = format(curDate);
                        lookup[curDate] = curStat;
                    }
                    var lastValue;
                    while((i+=step) < stop){
                        var key = format(new Date(i));
                        var curVal = key in lookup ? lookup[key].value : NaN;
                        console.log(name,curVal);
                        statValues.push(curVal);
                    }
                 //console.log(statValues);
                 callback(null,statValues);
                }, name);
        }

这是我看到的绘制的屏幕截图,每个度量都绘制相同的值(我验证的是不正确的数据)。 输出
