我正在尝试使用d3.js版本4进行条形图,我正在尝试制作垂直轴,它给出了以下错误:Bn(d3.min.js:2)处的未捕获错误在main.js:88
的Kn.vp [as ease](d3.min.js:5)这是我的代码:
var bardata = [];
for (var i=0; i < 20; i++){
bardata.push(Math.random())
}
bardata.sort(function compareNumbers(a,b){
return a -b;
})
var height = 400,
width = 600,
barWidth = 50,
barOffset = 5;
var tempColor;
var yScale = d3.scaleLinear()
.domain([0, d3.max(bardata)])
.range([0, height]);
var xScale = d3.scaleBand()
.domain(d3.range(0, bardata.length))
.padding(0.1)
.range([0, width]);
var tooltip = d3.select('body').append('div')
.style('position', 'absolute')
.style('padding', '0 10px')
.style('background', 'white')
.style('opacity', 0)
var myChart = d3.select('#chart').append('svg')
.attr('width', width)
.attr('height', height)
.append('g')
.style('background', '#C9D7D6')
.selectAll('rect').data(bardata)
.enter().append('rect')
.style('fill', '#C61C6F')
.attr('width', xScale.bandwidth())
.attr('x', function(d, i) {
return xScale(i);
})
.attr('height', 0)
.attr('y', height)
.on('mouseover', function(d){
d3.select(this)
.style('opacity', 0.5)
})
.on('mouseleave', function(d){
d3.select(this)
.style('opacity', 1)
})
.on('mouseover', function(d){
tooltip.transition()
.style('opacity', 0.9)
tooltip.html(d)
.style('left', (d3.event.pageX - 35) + 'px')
.style('top', (d3.event.pageY - 30) + 'px')
tempColor = this.style.fill;
d3.select(this)
.style('opacity', 0.5)
.style('fill', 'yellow')
})
.on('mouseleave', function(d){
tempColor = this.style.fill;
d3.select(this)
.style('opacity', 1)
.style('fill', '#C61C6F')
})
myChart.transition()
.attr('height', function(d){
return yScale(d);
})
.attr('y', function(d){
return height - yScale(d);
})
.delay(function(d, i){
return i * 20;
})
.duration(1000)
.ease('elastic')
var vAxis = d3.svg.axis()
.scale(yScale)
.orient('left')
.ticks(10)
var vGuide = d3.select('svg').append('g')
vAxis(vGuide)
vGuide.attr('transform', 'translate(35,0)')

答案 0 :(得分:1)
而不是
myChart.transition()
.attr('height', function(d){
return yScale(d);
})
.attr('y', function(d){
return height - yScale(d);
})
.delay(function(d, i){
return i * 20;
})
.duration(1000)
.ease('elastic')//INCORRECT
应该是
myChart.transition()
.attr('height', function(d){
return yScale(d);
})
.attr('y', function(d){
return height - yScale(d);
})
.delay(function(d, i){
return i * 20;
})
.duration(1000)
.ease(d3.easeElastic)
