I am trying to plot a line chart from a Javascript array. While parsing the date i get an error which says
d3.v3.min.js:1 Error: attribute d: Expected number, "MNaN,0LNaN,450".o @ d3.v3.min.js:1
I tried have tried the suggestions mentioned in this stack overflow question : d3.js parsing date error with csv file. But I am still facing the same issue. Any idea what I am doing wrong here. The same works perfectly when I try running with tsv input.
Here is my code :
<script src="//d3js.org/d3.v3.min.js"></script>
<script>
var data = [
{
"date": "01-Jan-16",
"close": "20"
},
{
"date": "05-Jan-16",
"close": "100"
}
];
var formatDate = d3.time.format("%d-%b-%y");
function type(d) {
d.date = formatDate.parse(d.date);
d.close = +d.close;
return d;
}
var margin = {
top: 20,
right: 20,
bottom: 30,
left: 50
},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
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.date);
})
.y(function (d) {
return y(d.close);
});
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 + ")");
x.domain(d3.extent(data, function (d) {
return d.date;
console.log(d.date);
}));
y.domain(d3.extent(data, function (d) {
return d.close;
console.log(d.close);
}));
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("Price ($)");
svg.append("path")
.datum(data)
.attr("class", "line")
.attr("d", line);
</script>
