引言
之前的文章，咱们介绍过横向和竖向，具体的内容，请看
- React CSS 绘制横向柱状图
- React CSS 绘制竖状柱状图
这次，结合起来，横向和竖向，一起画
主要设计来源
三个部分
<ul className="vertical"> <li className="vertical_li">100</li> <li className="vertical_li">75</li> <li className="vertical_li">50</li> <li className="vertical_li">25</li> <li className="vertical_li">0</li> </ul>
display 布局
.vertical {
height: 337px;
font-size: 12px;
font-weight: bold;
color: #9eadca;
display: flex;
flex-direction: column;
justify-content: space-between;
}
<ul className="crosswise"> <li>0</li> <li>25</li> <li>50</li> <li>75</li> <li>100</li> </ul>
display 布局
.crosswise {
width: 335px;
font-size: 12px;
font-weight: bold;
color: #9eadca;
display: flex;
flex-direction: row;
justify-content: space-between;
margin-top: -31px;
margin-left: -21px;
}
<div className="point_list">
{list.map((item, index) => {
return (
<div
className="point"
style={{ top: `${100 - parseFloat(item.y)}%`, left: `${item.x}%` }}
onMouseEnter={() => onMouseEnter(item, index)}
onMouseLeave={() => onMouseLeave(index)}
key={index}
>
{item.name}
</div>
)
})}
</div>
动态位置使用绝对定位
.point_list {
width: 308px;
height: 308px;
position: absolute;
top: 0px;
left: 0px;
}
具体的位置，是通过传入的参数来进行控制的。如果传入的参数不是具体的位置数值，前端也可以进行二次的计算。这里我就不演示了。之前的文章都有介绍，感兴趣的小伙伴可以去前两篇文章看一下。
