D3 remove comma delimiters for thousands

Question

I have a .json with 3 columns where one of them is 'Year'. The column contains only years. No dates!.

When I am graphing it on the 'x' axis the years come out with a comma delimiter for thousands.

So in the .json the date is this format :"Year":1990 and on the 'x' axis it comes out like that 1,990

I have been trying to figure out how to parse the year but I have no luck so far. I have tried the following:

var parseDate = d3.time.format("%y").parse

var x = d3.time.scale()
.range([0, width]);

//further down

d3.json("waterData.json", function(error, json) {

// Attach Data
var data = json.data;

// Select Data for X and Y
var axis1 = 'Year'; 
var axis2 = 'Ratio'

// Convert String into Numbers
data.forEach(function(d) {

///axis1 = parseDate(axis1);

d[axis1] = +d[axis1]
d[axis2] = +d[axis2]
});

 x.domain(d3.extent(data, function(d) { return d[axis1]; }));
 y.domain(d3.extent(data, function(d) { return d[axis2]; }));


 svg.append("g")
  .attr("class", "x axis")
  .attr("transform", "translate(0," + (height+10) + ")")
  .call(xAxis)
 .append("text")
  .attr("class", "label")
  .attr("x", width)
  .attr("y", -40)
  .text(axis1)

 svg.append("g")
  .attr("class", "y axis")
  .attr("transform", "translate("+ -10 + "," + 0 + ")")
  .call(yAxis)
 .append("text")
  .attr("class", "label")
  .attr("x", 10)
  .style("fill", "#666")
  .style("text-anchor", "start")
  .text(axis2)

Any suggestions of how to get rid of the comma delimiter. Or to figure out how to parse the date.

Answer 1

You should add .tickFormat(d3.format("d")) to your xAxis:

var xAxis = d3.svg.axis().scale(x).orient("bottom").tickFormat(d3.format("d"));
