這篇文章主要介紹了React?less?實(shí)現(xiàn)縱橫柱狀圖示例詳解，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進(jìn)步，早日升職加薪

引言

之前的文章，咱們介紹過橫向和豎向，具體的內(nèi)容，請(qǐng)看

這次，結(jié)合起來，橫向和豎向，一起畫

主要設(shè)計(jì)來源

三個(gè)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>

動(dòng)態(tài)位置使用絕對(duì)定位

.point_list {
  width: 308px;
  height: 308px;
  position: absolute;
  top: 0px;
  left: 0px;
}

具體的位置，是通過傳入的參數(shù)來進(jìn)行控制的。如果傳入的參數(shù)不是具體的位置數(shù)值，前端也可以進(jìn)行二次的計(jì)算。這里我就不演示了。之前的文章都有介紹，感興趣的小伙伴可以去前兩篇文章看一下。
