如何在每个顶部堆叠 Javascript/D3 栏

问题描述 投票：0回答：1

我正在编写一个数据条形图，显示多种攻击策略和其他信息。策略显示在 X 轴上，并且已排序。我希望当有多个相同的策略相互堆叠时出现这种情况。堆叠条形图的所有其他示例都使用 .stack，我很确定这不适用于这种情况。

任何帮助将不胜感激，因为我不知道如何制作，使盒子堆叠在一起

使用

tacticCount
保存战术数量。

将栏（

rect
）和文本放入
<g>
中，在
<g>
上更改
taticCount
的translateY。

// set the dimensions and margins of the graph
var margin = {
    top: 30,
    right: 30,
    bottom: 70,
    left: 60
  },
  width = 1000 - margin.left - margin.right,
  height = 500 - margin.top - margin.bottom;
barheight = 60;

// append the svg object to the body of the page
var svg = d3.select("#my_dataviz")
  .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 + ")");

// Parse the Data
d3.csv("https://raw.githubusercontent.com/BaileyHCUDenver/KPCUDTEST/main/test-data-short.csv", function(data) {
  // X axis
  var x = d3.scaleBand()
    .range([0, width])
    .domain(data.map(function(d) {
      return d.tactic;
    }))
    .padding(0.2);
  svg.append("g")
    .attr("transform", "translate(0," + height + ")")
    .call(d3.axisBottom(x))
    .selectAll("text")
    .attr("transform", "translate(-10,0)rotate(-)")
    .style("text-anchor", "end");

  // Add Y axis //Not needed to show the Y axis because their is no need for it 
  //var y = d3.scaleLinear()
  //.domain([0, 20])
  //.range([ height, 0]);
  //svg.append("g")
  //.call(d3.axisLeft(y));

  // Bars
  let tacticCount = {}
  const barItemContainers = svg.selectAll("mybar")
    .data(data)
    .enter()
    .append('g')
    .attr('transform', (d) => {
      tacticCount[d.tactic] = (tacticCount[d.tactic] || 0) + 1
      return `translate(${x(d.tactic)},${height - barheight * tacticCount[d.tactic]})`
    });
  barItemContainers.append("rect")
    .attr("width", x.bandwidth())
    .attr("height", barheight)
    .attr("fill", "#FFFFFF") //Fill in with white
    .attr("stroke", "black") // Black outline color
    .attr("stroke-width", ); // Outline width (adjust as needed)
  barItemContainers.append("text")
    .text(d => d.title) // Use the 'value' field from your data
    .attr("x", x.bandwidth() / 2) // Center the text
    .style("text-anchor", "middle") // Center-align the text
    .style("font-size", "9px") // Set font size
    .style("fill", "black"); // Set text color
  barItemContainers.append("text")
    .text(d => d.tactic) // Use the 'value' field from your data
    .attr("x", x.bandwidth() / 2) // Center the text
    .attr("y", 20) // Adjust the vertical position
    .style("text-anchor", "middle") // Center-align the text
    .style("font-size", "9px") // Set font size
    .style("fill", "black"); // Set text color

})
