问题描述
这是
代码:
var data = [
{
age:低于18,
value:582.13,
color:#B3DA29
},
{
age:18 - 22,
value:583.98,
color:#78C0F2
},
{
age:23 - 34,
value:603.00,
color:#9B58B5
},
{
age:35 - 60,
value:607.70,
color:#E54C3C
},
{
age:60 - Above,
value:610.00,
color:#F2519D
}
];
var margin = {top:20,right:20,bottom:30,left:40},
width = 400 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
var x = d3.scale.ordinal()
.rangeRoundBands([0,width],.1);
var y = d3.scale.linear()
.range([height,0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient(bottom);
var yAxis = d3.svg.axis()
.scale(y)
.orient(left)
.ticks(10,% );
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 +));
x.domain(data.map(function(d){return d.age;}));
y.domain([0,d3.max(data,function(d){return d.value;})]);
svg.append(g)
.attr(class,x axis)
.attr(transform height +))
.call(xAxis);
var tooltip = d3.select(body)append(div)
.attr(class,tooltip)
.style ,0);
svg.selectAll(。bar)
.data(data)
.enter()。append(rect)
.attr ,bar)
.attr(x,function(d){return x(d.age);})
.attr(width,x.rangeBand b $ b .attr(y,function(d){return y(d.value);})
.attr(height,function(d){return height - y(d.value) ;})
.style(fill,function(d){return d.color;})
.attr(rx,10)
.attr(ry 10)
.on(mouseover,function(d){
tooltip.transition()。duration(200).style(opacity,.9);
tooltip.html (Count:+ d.value)
.style(left,(d3.event.pageX)+px)
.style(top,(d3.event.pageY - 28)+px);
})
.on(mouseout,function(d){
tooltip.transition ,0);
});
解决方案
这是它的工作原理。
更新了 小提琴
。
svg.selectAll(。backgound-bar)
.data (数据)
.enter()
.append(rect)
.attr(class,background-bar)
.attr(x函数(d){return x(d.age);})
.attr(width,x.rangeBand())
.attr(y (800);})
.attr(height,height)
.style(fill,#ddd)
.attr(rx,10)
.attr(ry,10)
创建 svg
元素 background-bar
。
而 x
和 y
保持与您之前定义的相同。
height
变量定义。
希望这有助于:)
This is a follow-up question to this question.
How do I get the striped grey scale in the background which represents 100% and is parallel to Y-axis?
Code:
var data = [
{
"age": "Under 18",
"value": "582.13",
"color": "#B3DA29"
},
{
"age": "18 - 22",
"value": "583.98",
"color": "#78C0F2"
},
{
"age": "23 - 34",
"value": "603.00",
"color": "#9B58B5"
},
{
"age": "35 - 60",
"value": "607.70",
"color": "#E54C3C"
},
{
"age": "60 - Above",
"value": "610.00",
"color": "#F2519D"
}
];
var margin = {top: 20, right: 20, bottom: 30, left: 40},
width = 400 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
var x = d3.scale.ordinal()
.rangeRoundBands([0, width], .1);
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left")
.ticks(10, "%");
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 + ")");
x.domain(data.map(function(d) { return d.age; }));
y.domain([0, d3.max(data, function(d) { return d.value; })]);
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
var tooltip = d3.select("body").append("div")
.attr("class", "tooltip")
.style("opacity", 0);
svg.selectAll(".bar")
.data(data)
.enter().append("rect")
.attr("class", "bar")
.attr("x", function(d) { return x(d.age); })
.attr("width", x.rangeBand())
.attr("y", function(d) { return y(d.value); })
.attr("height", function(d) { return height - y(d.value); })
.style("fill", function(d) { return d.color; })
.attr("rx", 10)
.attr("ry", 10)
.on("mouseover", function(d) {
tooltip.transition().duration(200).style("opacity", .9);
tooltip.html("Count: " + d.value)
.style("left", (d3.event.pageX) + "px")
.style("top", (d3.event.pageY - 28) + "px");
})
.on("mouseout", function(d) {
tooltip.transition().duration(500).style("opacity", 0);
});
解决方案
Here's how it works.
Updated the fiddle
.
svg.selectAll(".backgound-bar") .data(data) .enter() .append("rect") .attr("class", "background-bar") .attr("x", function(d) { return x(d.age); }) .attr("width", x.rangeBand()) .attr("y", function(d) { return y(800); }) .attr("height", height) .style("fill", "#ddd") .attr("rx", 10) .attr("ry", 10)
Created a svg
element with the class background-bar
.
And the x
and y
remains the same as you've defined prior.
But the height of the bars are given to the height
variable defined.
Hope this helps :)
