Horizontal axis text alignment

[xuexnGo]

Can I set the text alignment direction for the horizontal axis

[xuri]

Thanks for your issue. I added new field Alignment in the ChartAxis data type to support set chart axis text direction and rotation. For example:

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
        }
        f.SetSheetRow("Sheet1", cell, &row)
    }
    if err := f.AddChart("Sheet1", "E1", &excelize.Chart{
        Type: excelize.Col3DClustered,
        Series: []excelize.ChartSeries{
            {
                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: []excelize.RichTextRun{
            {
                Text: "Fruit 3D Clustered Column Chart",
            },
        },
        XAxis: excelize.ChartAxis{
+           Alignment: excelize.Alignment{
+               Vertical:     "wordArtVertRtl",
+               TextRotation: 0,
+           },
        },
    }); err != nil {
        fmt.Println(err)
        return
    }
    // Save spreadsheet by the given path.
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}

Please upgrade to the master branch code by following command, and this feature will be released in the next version 2.9.1.
