javascript — дневная / часовая тепловая карта + mySQL

Я пытаюсь вписать мой набор данных в пример здесь: (http://bl.ocks.org/tjdecke/5558084).

Вот мой d3js:

     var margin = { top: 50, right: 0, bottom: 100, left: 30 },
width = 600 - margin.left - margin.right,
height = 430 - margin.top - margin.bottom,
gridSize = Math.floor(width / 24),
legendElementWidth = gridSize*2,
buckets = 9,
colors =     ["#ffffd9","#edf8b1","#c7e9b4","#7fcdbb","#41b6c4","#1d91c0","#225ea8","#25 3494","#081d58"], // alternatively colorbrewer.YlGnBu[9]
days = ["Mo", "Tu", "We", "Th", "Fr", "Sa", "Su"],
times = ["1a", "2a", "3a", "4a", "5a", "6a", "7a", "8a", "9a", "10a", "11a", "12a", "1p", "2p", "3p", "4p", "5p", "6p", "7p", "8p", "9p", "10p", "11p", "12p"];


d3.json("/test/heatmap.php", function(error, data) {
data.forEach(function(d) {
console.log(d);
day= +d.day;
hour= +d.hour;
value= +d.value;
});
},
function(error, data) {
var colorScale = d3.scale.quantile()
.domain([0, buckets - 1, d3.max(data, function (d) { return d.value; })])
.range(colors);
console.log(d3.max(data, function (d) { return d.value; }))
;
console.log("test");

var svg = d3.select(".wpd3-8-3").append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");

var dayLabels = svg.selectAll(".dayLabel")
.data(days)
.enter().append("text")
.text(function (d) { return d; })
.attr("x", 0)
.attr("y", function (d, i) { return i * gridSize; })
.style("text-anchor", "end")
.attr("transform", "translate(-6," + gridSize / 1.5 + ")")
.attr("class", function (d, i) { return ((i >= 0 && i <= 4) ? "dayLabel mono axis axis-workweek" : "dayLabel mono axis"); });

var timeLabels = svg.selectAll(".timeLabel")
.data(times)
.enter().append("text")
.text(function(d) { return d; })
.attr("x", function(d, i) { return i * gridSize; })
.attr("y", 0)
.style("text-anchor", "middle")
.attr("transform", "translate(" + gridSize / 2 + ", -6)")
.attr("class", function(d, i) { return ((i >= 7 && i <= 16)      ? "timeLabel mono axis axis-worktime" : "timeLabel mono axis"); });

var heatMap = svg.selectAll(".hour")
.data(data)
.enter().append("rect")
.attr("x", function(d) { return (d.hour - 1) * gridSize; })
.attr("y", function(d) { return (d.day - 1) * gridSize; })
.attr("rx", 4)
.attr("ry", 4)
.attr("class", "hour bordered")
.attr("width", gridSize)
.attr("height", gridSize)
.style("fill", colors[0]);

heatMap.transition().duration(1000)
.style("fill", function(d) { return colorScale(d.value); });

heatMap.append("title").text(function(d) { return d.value; });

var legend = svg.selectAll(".legend")
.data([0].concat(colorScale.quantiles()), function(d) {      return d; })
.enter().append("g")
.attr("class", "legend");

legend.append("rect")
.attr("x", function(d, i) { return legendElementWidth * i; })
.attr("y", height)
.attr("width", legendElementWidth)
.attr("height", gridSize / 2)
.style("fill", function(d, i) { return colors[i]; });

legend.append("text")
.attr("class", "mono")
.text(function(d) { return "≥ " + Math.round(d); })
.attr("x", function(d, i) { return legendElementWidth * i; })
.attr("y", height + gridSize);
});

И пример моего php echo:

[{"day":"4","hour":"0","value":"91"},{"day":"7","hour":"0","value":"93"},{"day":"3","hour":"1","value":"71"},{"day":"4","hour":"1","value":"90"},{"day":"3","hour":"2","value":"96"},{"day":"4","hour":"2","value":"89"},{"day":"5","hour":"2","value":"88"},{"day":"3","hour":"3","value":"97"},{"day":"4","hour":"3","value":"88"},{"day":"5","hour":"3","value":"88"},{"day":"6","hour":"3","value":"89"},{"day":"4","hour":"4","value":"86"},{"day":"5","hour":"4","value":"86"},{"day":"6","hour":"4","value":"88"},{"day":"7","hour":"4","value":"91"},{"day":"4","hour":"5","value":"86"},{"day":"6","hour":"5","value":"88"},{"day":"7","hour":"5","value":"91"},{"day":"6","hour":"6","value":"88"},{"day":"7","hour":"6","value":"91"},{"day":"6","hour":"7","value":"86"},{"day":"6","hour":"8","value":"86"},{"day":"6","hour":"9","value":"86"},{"day":"6","hour":"10","value":"86"},{"day":"6","hour":"11","value":"85"},{"day":"3","hour":"12","value":"91"},{"day":"4","hour":"12","value":"82"},{"day":"5","hour":"12","value":"82"},{"day":"6","hour":"12","value":"84"},{"day":"4","hour":"13","value":"82"},{"day":"6","hour":"13","value":"85"},{"day":"6","hour":"14","value":"87"},{"day":"6","hour":"15","value":"88"},{"day":"6","hour":"16","value":"88"},{"day":"6","hour":"17","value":"88"},{"day":"6","hour":"18","value":"88"},{"day":"6","hour":"19","value":"89"},{"day":"6","hour":"20","value":"90"},{"day":"6","hour":"21","value":"91"},{"day":"6","hour":"22","value":"91"},{"day":"6","hour":"23","value":"93"}]

Я в тупике, потому что, когда я записываю результаты d3.json, он совпадает с результатами файла примера. То, что я заметил, в примере,

console.log(d3.max(data, function (d) { return d.value; }))

загружает с максимальным значением. Когда я загружаю свои значения, console.log, кажется, не печатает дальше шага d3.json.

Любой совет? Я немного озадачен после нескольких дней чтения и экспериментов.

Спасибо!
