Как поместить легенду в график ap ie в d3. js

1 голос
/ 03 мая 2020

У меня есть диаграмма p ie, созданная в d3. js, и я хочу поставить на нее легенду. Но почти вся документация, которую я до сих пор читал, относится только к d3. js версии 3, и многое изменилось для v5. Кто-то говорит, что в d3 уже есть создатель легенды, и я не понимаю, как его использовать. Пожалуйста, помогите.

Ниже приведен фрагмент кода диаграммы p ie: 

/** START OF PIE CHART */

var data = [{"region_iso_code":"PH-00","total_up_percentage":97.69},{"region_iso_code":"PH-01","total_up_percentage":99.83},{"region_iso_code":"PH-02","total_up_percentage":97.96},{"region_iso_code":"PH-03","total_up_percentage":99.29},{"region_iso_code":"PH-04","total_up_percentage":98.36},{"region_iso_code":"PH-05","total_up_percentage":98.02},{"region_iso_code":"PH-06","total_up_percentage":96.91},{"region_iso_code":"PH-07","total_up_percentage":99.75},{"region_iso_code":"PH-LAG","total_up_percentage":98.84}]

var svgCirWidth = 600, svgCirHeight = 300, radius = Math.min(svgCirWidth, svgCirHeight) / 2;

const pieContainer = d3.select("#pieChart")
    .append("svg")
    .attr("width", svgCirWidth)
    .attr("height", svgCirHeight);

//create group element to hold pie chart

var g = pieContainer.append("g")
    .attr("transform", "translate(" + 250 + "," + radius + ")");

var color = d3.scaleOrdinal()
    .range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"])

var pie = d3.pie().value(function (d) {
    return d.total_up_percentage;
});

var path = d3.arc()
    .outerRadius(radius)
    .innerRadius(0);

var arc = g.selectAll("arc")
    .data(pie(data))
    .enter() //means keeps looping in the data
    .append("g");

arc.append("path")
    .attr("d", path)
    .attr("fill", function (d) {
        return color(d.data.total_up_percentage);
    })
    .append("text")
    .text("afdaf");

var label = d3.arc()
    .outerRadius(radius)
    .innerRadius(0);

arc.append("text")
    .attr("transform", (d) => {
        return "translate(" + label.centroid(d) + ")";
    })
    .attr("text-anchor", "middle")
    .text((d) => {
        return d.data.total_up_percentage + "%"
    });
