三维曲面图

例如,创建如下效果的三维曲面图:

使用 Go 语言在 Excel 文档中创建三维曲面图

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{
        Type: excelize.Surface3D,
        Series: []excelize.ChartSeries{
            {

                Values:     "Sheet1!$B$2:$D$2",
            },
            {
                Name:       "Sheet1!$A$3",
                Categories: "Sheet1!$B$1:$D$1",

            },
        },
        Format: excelize.GraphicOptions{
            OffsetX: 15,
            OffsetY: 10,
        },
        Legend: excelize.ChartLegend{
            Position: "left",
        },
        Title: excelize.ChartTitle{
            Name: "三维曲面图",
        },
    }); err != nil {
        fmt.Println(err)
        return
    }
    // 保存工作簿
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}
