D3 x軸值堆積在左邊

我試圖做一個簡單的折線圖。 x軸將顯示10,100,1000等'值出於某種原因，我得到堆疊在x軸左側的所有值，而不是將它們均勻分佈在軸上。D3 x軸值堆積在左邊

var data = [ 
    {views:10, odds: 56}, 
    {views:100, odds: 64}, 
    {views:1000, odds: 81}, 
    {views:10000, odds: 95}, 
    {views:100000, odds: 99}, 
    {views:1000000, odds: 99}, 
    {views:10000000, odds: 100}, 
]; 

// Set the dimensions of the canvas/graph 
var margin = {top: 30, right: 20, bottom: 30, left: 50}, 
    width = 600 - margin.left - margin.right, 
    height = 270 - margin.top - margin.bottom; 

// Set the ranges 
var x = d3.scale.linear() 
.domain([ 
    d3.min(data, function(d) { return d.views; }), 
    d3.max(data, function(d) { return d.views; }) 
]) 
.range([0, width]); 

var y = d3.scale.linear() 
.domain([ 
    d3.min(data, function(d) { return d.odds; }), 
    d3.max(data, function(d) { return d.odds; }) 
]) 
.range([height, 0]); 

// Define the axes 
var xAxis = d3.svg.axis().scale(x) 
    .orient("bottom").ticks(7) 
    .tickValues(data.map((d)=>{ return d.views; })); 

var yAxis = d3.svg.axis().scale(y) 
    .orient("left").ticks(7); 

// Define the line 
var valueline = d3.svg.line() 
    .x(function(d) { return x(d.views); }) 
    .y(function(d) { return y(d.odds); }); 

// Adds the svg canvas 
var svg = d3.select("body") 
    .append("svg") 
     .attr("width", width + margin.left + margin.right) 
     .attr("height", height + margin.top + margin.bottom) 
    .append("g") 
     .attr("transform", 
       "translate(" + margin.left + "," + margin.top + ")"); 

    // Add the valueline path. 
    svg.append("path") 
     .attr("class", "line") 
     .attr("d", valueline(data)); 

    // Add the X Axis 
    svg.append("g") 
     .attr("class", "x axis") 
     .attr("transform", "translate(0," + height + ")") 
     .call(xAxis); 

    // Add the Y Axis 
    svg.append("g") 
     .attr("class", "y axis") 
     .call(yAxis);
