图表中的网格线，如何在此示例中获取-gridlinesinthechart,howtoobtaininthisexample

How to obtain grid lines in the following chart ? I have been trying to obtain grid lines by using d3noobs d3 tips and tricks. But this code doesn't work

如何在下图中获取网格线?我一直试图通过使用d3noobs d3技巧和技巧获得网格线。但是这段代码不起作用

       .grid.tick {
            stroke: lightgrey;
opacity: 0.7;
    }
  .grid path {
stroke-width: 0;
 }



        
 
  
    
         
          
  
  \\ script
    

      
    
    

  

and scatterchart.js

     var data = [[2,2], [2,5], [6,6], [6,7],[25,25]];

var margin = {top: 20, right: 15, bottom: 60, left: 60}
  , width = 960 - margin.left - margin.right
  , height = 500 - margin.top - margin.bottom;

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

var y = d3.scale.linear()
          .domain([0, d3.max(data, function(d) { return d[1]; })])
          .range([ height, 0 ]);

var chart = d3.select('body')
.append('svg:svg')
.attr('width', width + margin.right + margin.left)
.attr('height', height + margin.top + margin.bottom)
.attr('class', 'chart')

var main = chart.append('g')
.attr('transform', 'translate(' + margin.left + ',' + margin.top + ')')
.attr('width', width)
.attr('height', height)
.attr('class', 'main')   

// draw the x axis
var xAxis = d3.svg.axis()
.scale(x)
.orient('bottom');

main.append('g')
.attr('transform', 'translate(0,' + height + ')')
.attr('class', 'main axis date')
.call(xAxis);

// draw the y axis
var yAxis = d3.svg.axis()
.scale(y)
.orient('left');

main.append('g')
.attr('transform', 'translate(0,0)')
.attr('class', 'main axis date')
.call(yAxis);




var g = main.append("svg:g"); 

g.selectAll("scatter-dots")\\dots
  .data(data)
  .enter().append("svg:circle")
      .attr("cx", function (d,i) { return x(d[0]); } )\\x pos
      .attr("cy", function (d) { return y(d[1]); } )\\ y pos
      .attr("r", 8); \\ radius

Thus how to obtain grid lines in this chart ?

那么如何获得此图表中的网格线?

1 个解决方案

main.append("g")
    .attr("class", "grid")
    .attr("transform", "translate(0," + height + ")")
    .call(make_x_axis()
    .tickSize(-height, 0, 0)
    .tickFormat(""));
