如何使用angular指令使用范围json数据加载d3.js图,而不是使用graph.html文件。我已经引用了此网址url。但无法为折线图执行此操作。
任何人都可以帮我解决这个问题...
我的graph.html:
function getDate(d) {
var dt = new Date(d.date);
dt.setHours(0);
dt.setMinutes(0);
dt.setSeconds(0);
dt.setMilliseconds(0);
return dt;
}
function showData(obj, d) {
var coord = d3.mouse(obj);
var infobox = d3.select(".infobox");
// now we just position the infobox roughly where our mouse is
infobox.style("left", (coord[0] + 100) + "px" );
infobox.style("top", (coord[1] - 175) + "px");
$(".infobox").html(d);
$(".infobox").show();
}
function hideData() {
$(".infobox").hide();
}
var drawChart = function(data) {
// define dimensions of graph
var m = [10, 20, 10, 50]; // margins
var w = 250 - m[1] - m[3]; // width
var h = 100 - m[0] - m[2]; // height
data.sort(function(a, b) {
var d1 = getDate(a);
var d2 = getDate(b);
if (d1 == d2) return 0;
if (d1 > d2) return 1;
return -1;
});
var minDate = getDate(data[0]),
maxDate = getDate(data[data.length-1]);
var x = d3.time.scale().domain([minDate, maxDate]).range([0, w]);
var y = d3.scale.linear().domain([0, d3.max(data, function(d) { return d.trendingValue; } )]).range([h, 0]);
var line = d3.svg.line()
.x(function(d, i) {
return x(getDate(d)); //x(i);
})
.y(function(d) {
return y(d.trendingValue);
});
function xx(e) { return x(getDate(e)); };
function yy(e) { return y(e.trendingValue); };
var graph = d3.select("#chart").append("svg:svg")
.attr("width", w + m[1] + m[3])
.attr("height", h + m[0] + m[2])
.append("svg:g")
.attr("transform", "translate(" + m[3] + "," + m[0] + ")");
var xAxis = d3.svg.axis().scale(x).ticks(d3.time.months, 1).tickSize(-h).tickSubdivide(true);
var yAxisLeft = d3.svg.axis().scale(y).ticks(10).orient("left"); //.tickFormat(formalLabel);
graph
.selectAll("circle")
.data(data)
.enter().append("circle")
.attr("fill", "steelblue")
.attr("r", 5)
.attr("cx", xx)
.attr("cy", yy)
.on("mouseover", function(d) { showData(this, d.trendingValue);})
.on("mouseout", function(){ hideData();});
graph.append("svg:path").attr("d", line(data));
$("#chart").append("<div class='infobox' style='display:none;'>Test</div>");
}

我建议您按照一些简单的angular tutorials来更好地掌握基础知识,而不是混合两段代码并希望它能够正常运行。此外,一些简单的调试将在这里走得很远。
drawChart
,您正在调用drawchart
d3.select(element[0])
所有这一切都表明,一旦你解决了这些相对简单的错误,就会得到一些有用的代码:
var myAppModule = angular.module('chart', []);
angular.module('chart').controller('chartCtrl', function ($scope) {
$scope.myData = [{
"date": "2015-10-01",
"trendingValue": "244"
},
{
"date": "2015-07-01",
"trendingValue": "0"
},
{
"date": "2015-06-01",
"trendingValue": "117"
},
{
"date": "2015-05-01",
"trendingValue": "5353"
},
{
"date": "2015-04-01",
"trendingValue": "11159"
},
{
"date": "2015-03-01",
"trendingValue": "7511"
},
{
"date": "2015-02-01",
"trendingValue": "6906"
