我想构建堆叠图表栏。 要构建它我使用的是d3js版本3。 我在codepen上找到了一些模板并改变了我的需求。
但是当我在Mozilla Firefox中打开它时,它显示没有颜色:
我应该如何修改样式?
这是我的html和javascript代码:
<!DOCTYPE html>

<script data-require="d3@3.0.0" data-semver="3.0.0" src="https://d3js.org/d3.v3.min.js"></script>
<style type="text/css">
svg {
font: 10px sans-serif;
shape-rendering: crispEdges;
}
.axis path,
.axis line {
fill: none;
stroke: #000;
}
path.domain {

}
.y .tick line {
stroke: #ddd;
}
</style>
</head>

答案 0 :(得分:0)
通过向颜色添加哈希来修复它:
从:
const all_colors = ["3d3756", "f0ee42", "f4c7de"];
为:
const all_colors = ["#3d3756", "#f0ee42", "#f4c7de"];
