垂直线这个能用go.Line函数写吗

可以使用go.Line函数来绘制垂直线。示例如下：

import (
    "github.com/go-echarts/go-echarts/v2/components"
    "github.com/go-echarts/go-echarts/v2/types"
)

func drawVerticalLine() {
    line := []interface{}{
        []int{1, 2},
        []int{3, 4},
        []int{5, 6},
    }
    xData := []string{"A", "B", "C"}
    yData := []string{"1", "2", "3", "4", "5", "6"}

    graph := components.NewLine().
        SetGlobalOptions(
            components.WithInitializationOpts(opts.Initialization{
                Width:  "100%",
                Height: "500px",
                Theme:  "dark",
            }),
            components.WithTitleOpts(opts.Title{
                Title:    "Vertical Line",
                Subtitle: "This is a vertical line chart",
            }),
            components.WithLegendOpts(opts.Legend{Show: true}),
            components.WithTooltipOpts(opts.Tooltip{Show: true}),
            components.WithYAxisOpts(opts.YAxis{
                Type: "category",
                Data: yData,
            }),
            components.WithXAxisOpts(opts.XAxis{
                Type: "category",
                Data: xData,
            }),
        ).
        AddSeries("Category A", line, types.ChartLineOpts{Smooth: true})

    f, err := os.Create("vertical_line.html")
    if err != nil {
        panic(err)
    }

    graph.Render(f)
}

在上面的示例中，我们使用go-echarts库来绘制一个垂直线图。其中，我们使用了go.Line函数来定义线的坐标，将其传递给了AddSeries函数来添加到图表中。在设置x轴的类型为category时，可以用xData来指定x轴的标签。
