我是nvd3排行榜的新手.我需要一个折线图,x轴上的字符串值图表应该像这个条形图,但我需要一条线,而不是条形图

我的结果看起来像这个折线图 这些值都映射到x = 0

我的代码

nv.addGraph(function() {
    var chart = nv.models.lineChart()
    .useInteractiveGuideline(true) 
    .transitionDuration(350)
    .x(function(d) { return d.x}) 
    .y(function(d) { return d.y}) 
    .showLegend(true)
    .showYAxis(true)
    .showXAxis(true);

    chart.xAxis.tickValues(["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]);

    d3.select(element + ' svg')
    .datum(data) 
    .call(chart);

    nv.utils.windowResize(chart.update);

    return chart;
});

和我的数据

[{"color":"#a215af","key":"products","values":[
    {"label":"Monday","y":0,"x":"Monday"},
    {"label":"Tuesday","y":0,"x":"Tuesday"},
    {"label":"Wednesday","y":1,"x":"Wednesday"},
    {"label":"Thursday","y":6,"x":"Thursday"},
    {"label":"Friday","y":2,"x":"Friday"},
    {"label":"Saturday","y":0,"x":"Saturday"},
    {"label":"Sunday","y":13,"x":"Sunday"}]}] 

我尝试了很多,但不知道该怎么做.

任何帮助或建议都会很棒

像dcclassics提到的解决方案我使用数字值代替字符串,然后使用tickValues和tickFormat:

var days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]

chart.xAxis.tickValues([0, 1, 2, 3, 4, 5, 6])
.tickFormat(function(d){
    return days[d]
});
