我在调整React中d3图表的大小时遇到问题。我可以让SVG本身更改大小，但是SVG内部的图表没有更改。我在这里浏览了所有类似的问题，但无法弄清楚。
我尝试了viewbox和perserveaspectratio方法，但它没有更改图表的元素。现在，我添加了CS来更改SVG大小。我认为我走在正确的道路上，但缺少一些地方。
此处提供了组件代码：
class Chart extends Component {
componentDidMount() {
this.createChart();
}
createChart() {
var svg = d3.select("svg"),
margin = {top: 20, right: 20, bottom: 30, left: 40},
width = +svg.attr("width") - margin.left - margin.right,
height = +svg.attr("height") - margin.top - margin.bottom,
g = svg.append("g").attr("transform", "translate(" + margin.left + "," + margin.top + ")");
// The scale spacing the groups:
var x0 = d3.scaleBand()
.rangeRound([0, width])
.paddingInner(0.1);
// The scale for spacing each group's bar:
var x1 = d3.scaleBand()
.padding(0.05);
var y = d3.scaleLinear()
.rangeRound([height, 0]);
var z = d3.scaleOrdinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
const teamRef = {
"packers": packers,
"bears": bears,
"chargers": chargers
}
d3.csv(teamRef[this.props.team], function(d, i, columns) {
for (var i = 1, n = columns.length; i < n; ++i) d[columns[i]] = +d[columns[i]];
return d;
}).then(function(data) {
// console.log(data);
var keys = data.columns.slice(1);
// console.log('keys');
// console.log(keys);
x0.domain(data.map(function(d) { return d.Year; }));
x1.domain(keys).rangeRound([0, x0.bandwidth()]);
y.domain([0, d3.max(data, function(d) { return d3.max(keys, function(key) { return d[key]; }); })]).nice();
g.append("g")

legend.append("text")
.attr("x", width - 24)
.attr("y", 9.5)
.attr("dy", "0.32em")
.text(function(d) { return d; });
var filtered = [];

});
}
render() {
return (
<div>
<div id="container" className="svg-container">
<svg className="svg-content" width="900" height="500">
</svg>
</div>
<a onClick={this.props.onBack} className="col-xs-1 pt3 black b navbar-left">Back</a>
</div>
)
}
}
export default Chart;
和CS：
.svg-container {
display: inline-block;
position: relative;
width: 100%;
padding-bottom: 100%;
vertical-align: top;
overflow: hidden;
}
.svg-content {
display: inline-block;
position: absolute;
top: 0;
left: 0;
}

请参阅左上方的图表，svg会发生变化，但条形不会发生变化。
感谢您的帮助！我已经坚持了很长时间。
