How can I add a vertical line on the X axis in a Google Chart' chart (Line type)?

[Belen Dominguez Garcia]

I'm working with react and Google Charts and I just found a problem that I can not find the solution for.

I have this component

   

 <Chart chartType='Line' data={data} options={options} />

And here are the values to data and options:

   

const data = [
            ["Year", "Value"],
            ["2020", 48.92],
            ["2025", 49.45],
            ["2030", 49.24],
            ["2035", 50.93],
            ["2040", 49.62],
            ["2025", 49.62]
     ];
        var options = {
            legend: "none",
            colors: ['#a52714', '#097138']
        };

This chart works well, but now **I need add a vertical line only in the year 2025**.

How can I do it?

Thanks for your help.
