i wnat to pass the values of slice to the controller in mvc.i have the value in the var id. Now i want to pass that value to my controller.Below is my code to generate the pie chart
<script>
var width = 960,
height = 500,
radius = Math.min(width, height) / 2;
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
var arc = d3.svg.arc()
.outerRadius(radius - 10)
.innerRadius(0);
var pie = d3.layout.pie()
.sort(null)
.value(function (d) { return d.population; });
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
d3.csv("/temp/data.csv", function (error, data) {
data.forEach(function (d) {
d.population = +d.population;
});
var g = svg.selectAll(".arc")
.data(pie(data))
.enter().append("g")
.attr("class", "arc");
g.append("path")
.attr("d", arc)
.style("fill", function (d) {
return color(d.data.age);})
.on('click', function (d) {
var id = d.data.age;
});
g.append("text")
.attr("transform", function (d) { return "translate(" + arc.centroid(d) + ")"; })
.attr("dy", ".35em")
.style("text-anchor", "middle")
.text(function (d) { return d.data.age; })
});
</script>
