Excelize 开发者指南1.5. 在 Excel 文档中创建图表
使用 Excelize 生成图表十分简单，仅需几行代码。您可以根据工作表中的已有数据构建图表，或向工作表中添加数据并创建图表。
package main
import (
"fmt"
"github.com/xuri/excelize/v2"
)
func main() {
categories := map[string]string{
"A2": "Small", "A3": "Normal", "A4": "Large", "B1": "Apple", "C1": "Orange", "D1": "Pear"}
values := map[string]int{
"B2": 2, "C2": 3, "D2": 3, "B3": 5, "C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}
f := excelize.NewFile()
for k, v := range categories {
f.SetCellValue("Sheet1", k, v)
}
for k, v := range values {
f.SetCellValue("Sheet1", k, v)
}
if err := f.AddChart("Sheet1", "E1", `{
"type": "col3DClustered",
"series": [
{
"name": "Sheet1!$A$2",
"categories": "Sheet1!$B$1:$D$1",
"values": "Sheet1!$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"
}],
"title":
{
"name": "Fruit 3D Clustered Column Chart"
}
}`); err != nil {
fmt.Println(err)
return
}
// 根据指定路径保存文件
if err := f.SaveAs("Book1.xlsx"); err != nil {
fmt.Println(err)
}
}
