三维簇状条形图 {#bar3DClustered}

例如，创建如下效果的三维簇状条形图：

package main

import (
    "fmt"

    "github.com/xuri/excelize/v2"
)

func main() {
    f := excelize.NewFile()
    defer func() {
        if err := f.Close(); err != nil {
            fmt.Println(err)
        }
    }()
    for idx, row := range [][]interface{}{
        {nil, "Apple", "Orange", "Pear"},
        {"Small", 2, 3, 3},
        {"Normal", 5, 2, 4},
        {"Large", 6, 7, 8},
    } {
        cell, err := excelize.CoordinatesToCellName(1, idx+1)
        if err != nil {
            fmt.Println(err)
            return
        }
        if err := f.SetSheetRow("Sheet1", cell, &row); err != nil {
            fmt.Println(err)
            return
        }
    }
    if err := f.AddChart("Sheet1", "E1", &excelize.Chart{

    // 保存工作簿
