How do I display dates on the x-axis for nvd3 / d3.js?
Solution 1:
Try creating a new Date object before the tick for the x-axis gets passed to the formatter:
.tickFormat(function(d) { return d3.time.format('%b %d')(new Date(d)); })
See the documentation for d3.time.format to see how you can customize the formatting string.
Solution 2:
Adding on to seliopou's answer, to correctly align the dates with the x-axis, try this:
chart.xAxis
.tickFormat(function(d) {
return d3.time.format('%d-%m-%y')(new Date(d))
});
chart.xScale(d3.time.scale()); //fixes misalignment of timescale with line graph
