曲面图

例如，创建如下效果的曲面图：

使用 Go 语言在 Excel 文档中创建曲面图

  1. package main
  3. import (
  4.     "fmt"
  6.     "github.com/360EntSecGroup-Skylar/excelize"
  7. )
  9. func main() {
  10.     categories := map[string]string{"A2": "Small", "A3": "Normal", "A4": "Large", "B1": "Apple", "C1": "Orange", "D1": "Pear"}
  11.     values := map[string]int{"B2": 2, "C2": 3, "D2": 3, "B3": 5, "C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}
  12.     f := excelize.NewFile()
  13.     for k, v := range categories {
  14.         f.SetCellValue("Sheet1", k, v)
  15.     }
  16.     for k, v := range values {
  17.         f.SetCellValue("Sheet1", k, v)
  18.     }
  19.     if err := f.AddChart("Sheet1", "E1", `{"type":"contour","series":[{"name":"Sheet1!$A$2","categories":"","values":"Sheet1!$B$2:$D$2"},{"name":"Sheet1!$A$3","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$3:$D$3"},{"name":"Sheet1!$A$4","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$4:$D$4"}],"format":{"x_scale":1.0,"y_scale":1.0,"x_offset":15,"y_offset":10,"print_obj":true,"lock_aspect_ratio":false,"locked":false},"legend":{"position":"left","show_legend_key":false},"title":{"name":"曲面图"}}`); err != nil {
  20.         fmt.Println(err)
  21.     }
  22.     // 保存工作簿
  23.     if err := f.SaveAs("Book1.xlsx"); err != nil {
  24.         fmt.Println(err)
  25.     }
  26. }
