Question

i\'m new to nvd3 charts. i need a line chart, with string-values on the x-axis the chart should be like this Bar Chart, but i need a line, instead of bars

my result

Answer 1

like dcclassics mentioned i took number values instead of strings and then used tickValues and 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]
});

this solutions worked for me

Answer 2

Working solution:

var data = [{"color":"#a215af","key":"products","values":[
    {"y":0,"x":0},
    {"y":0,"x":1},
    {"y":1,"x":2},
    {"y":6,"x":3},
    {"y":2,"x":4},
    {"y":0,"x":5},
    {"y":13,"x":6}]}] 

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);

  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]
    });

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

  nv.utils.windowResize(chart.update);

  return chart;
});
