[Solved]-How Can I display dates on the x-axis using nvd3 line charts-d3.js

There are two things:

1. you can setup the ticker;
2. and you can convert your value from a random string to something NVD3 understands

If you provide a String on the X-axis, NVD3 doesn't know how to order it, so a Date object is required. You can setup your chart like this:

chart.xAxis
  .x(function(d) { new Date(d.x) }) // this convert the data object
  .axisLabel('Date')
  .tickFormat(function(d) { return d3.time.format('%Y-%m-%d')(new Date(d)); }); // this convert the ticker
