更新時(shí)間：2025年07月13日 09:11:10 作者：天使的同類

本文介紹了使用Echarts實(shí)現(xiàn)立體柱狀圖的方法,文中通過(guò)示例代碼介紹的非常詳細(xì),對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

Echarts柱狀圖中文網(wǎng)：https://echarts.apache.org/examples/zh/index.html#chart-type-bar

效果展示：

主要實(shí)現(xiàn)過(guò)程是三部分的組合，最上面是一個(gè)橢圓，中間是正常的柱子，下方再加上一個(gè)橢圓，就出來(lái)立體的效果。

分別展示三段組合代碼：

頂部的橢圓形(象形柱圖):pictorialBar

      {
        type: "pictorialBar", // pictorialBar(象形柱圖)
        symbolSize: [20, 5], // 圖形的大小用數(shù)組分別比表示寬和高,也樂(lè)意設(shè)置成10相當(dāng)于[10,10]
        symbolOffset: [0, 3], // 圖形相對(duì)于原本位置的偏移
        z: 12, // 象形柱狀圖組件的所有圖形的 z 值.控制圖形的前后順序.z 值小的圖形會(huì)被 z 值大的圖形覆蓋.
        itemStyle: {
          color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
            {
              offset: 0,
              color: "#17A8A0",
            },
            {
              offset: 1,
              color: "#5AEA80",
            },
          ]),
        },
        data: columnData.value,
      },

中間的柱子:bar

      {
        name: "發(fā)電量",
        type: "bar",
        barWidth: 20,
        itemStyle: {
          color: {
            x: 0,
            y: 0,
            x2: 0,
            y2: 1,
            type: "linear",
            global: false,
            colorStops: [
              {
                offset: 0,
                color: "#17A8A0",
              },
              {
                offset: 1,
                color: "#5AEA80",
              },
            ],
          },
        },
        data: columnData.value,
        label: {
          show: true,
          position: "top",
          color: "#FFFFFF",
          fontSize: 14,
        },
      },

底部的橢圓形(象形柱圖):pictorialBar

     {
        type: "pictorialBar",
        symbolSize: [20, 10],
        symbolOffset: [0, -5],
        z: 12,
        symbolPosition: "end",
        itemStyle: {
          color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
            {
              offset: 0,
              color: "#17A8A0",
            },
            {
              offset: 1,
              color: "#5AEA80",
            },
          ]),
        },
        data: columnData.value,
      },

整體代碼如下：

    style="width: 100%; height: 270px"
