According the demo on http://bl.ocks.org/mbostock/3883245
I don't know how format time on xAxis
this is my code : js:
var data = [{ "creat_time": "2013-03-12 15:09:04", "record_status": "ok", "roundTripTime": "16" }, { "creat_time": "2013-03-12 14:59:06", "record_status": "ok", "roundTripTime": "0" }, { "creat_time": "2013-03-12 14:49:04", "record_status": "ok", "roundTripTime": "297" }, { "creat_time": "2013-03-12 14:39:06", "record_status": "ok", "roundTripTime": "31" },{ "creat_time": "2013-03-12 14:29:03", "record_status": "ok", "roundTripTime": "0" }]; var margin = {top: 20, right: 20, bottom: 30, left: 50}; var width = 960 - margin.left - margin.right; var height = 500 - margin.top - margin.bottom; var parseDate = d3.time.format("%Y-%m-%d %H:%M:%S").parse; var x = d3.time.scale() .range([0, width]); var y = d3.scale.linear() .range([height, 0]); var xAxis = d3.svg.axis() .scale(x) .orient("bottom"); var yAxis = d3.svg.axis() .scale(y) .orient("left"); var line = d3.svg.line() .x(function(d) { return x(d.creat_time); }) .y(function(d) { return y(d.roundTripTime); }); var svg = d3.select("body").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 + ")"); data.forEach(function(d) { d.creat_time = parseDate(d.creat_time); d.roundTripTime = +d.roundTripTime; }); x.domain(d3.extent(data, function(d) { return d.creat_time; })); y.domain(d3.extent(data, function(d) { return d.roundTripTime;})); svg.append("g") .attr("class", "x axis") .attr("transform", "translate(0," + height + ")") .call(xAxis); svg.append("g") .attr("class", "y axis") .call(yAxis) .append("text") .attr("transform", "rotate(-90)") .attr("y", 6) .attr("dy", ".71em") .style("text-anchor", "end") .text("return time(ms)"); svg.append("path") .datum(data) .attr("class", "line") .attr("d", line);
this is svg:
In svg , time is 12-hour clock ,but in my data time is 24-hour clock . how to keep the same format on svg and data?
Any help is appreciated. (ps:I hope you don't mind my English,it's so bad.)
