dc.js x 轴显示为小数而不是整数

Question

我有一个折线图，a 轴是周数，y 轴是容量。但是，由于某种原因，x 轴的间隔将增加 0.5...我希望它从 1、2、3、4 等开始，而不是 1、1.5、2、2.5、3、3.5，等等

这是我的代码供参考

let chart = dc.lineChart("#chart");
let ndx = crossfilter(results);
            
let weekDimension = ndx.dimension(function (d) {
     return d.week = +d.week;
});
                
function reduceAdd(p, v) {
    ++p.count;
    p.total += v.capacity;
    p.average = p.total / p.count;
    return p;
}

function reduceRemove(p, v) {
    --p.count;
    p.total -= v.capacity;
    p.average = p.count ? p.total / p.count : 0;
    return p;
}

function reduceInitial() {
    return { count: 0, total: 0, average: 0 };
} 

let capacityGroup = weekDimension.group().reduce(reduceAdd, reduceRemove, reduceInitial);
            
chart.width(360)
    .height(200)
    .margins({ top: 20, right: 20, bottom: 50, left: 30 })
    .mouseZoomable(false)
    .x(d3.scale.linear().domain([1, 52]))
    .renderHorizontalGridLines(true)
    .brushOn(false)
    .dimension(weekDimension)
    .valueAccessor(function (d) {
        return d.value.average;
    })
    .group(capacityGroup);

dc.renderAll('chart');

这就是结果的样子

{month : "1", capacity: "48"}
{month : "1", capacity: "60"}
{month : "2", capacity: "67"}
{month : "2", capacity: "60"}
{month : "2", capacity: "66"}
{month : "3", capacity: "52"}
{month : "3", capacity: "63"}
{month : "4", capacity: "67"}
{month : "4", capacity: "80"}
{month : "5", capacity: "61"}
{month : "5", capacity: "66"}
{month : "5", capacity: "54"}

我需要做什么才能确保我的 x 轴间隔符合数据集中的值？我试过 capacityChart.xAxis().tickFormat(d3.format('.0f')); 但是 x 轴是 1, 1, 2, 2, 3, 3, 4, 4, 5, 5..

任何帮助将不胜感激！

多亏了 Gordon，设法弄明白了！

我capacityChart.xAxis().ticks(maxWeek)解决了这个问题
