I’m sorry to have to ask, I’m really new at this. I’ve made a little graph using ticks along a X axis of dates. The graph is split into 3 sections. I’d like to highlight Oct 3rd 2021 with a vertical line or tick in a different color/stroke, but I don’t know how to.

Relevant code:
Plot.plot({
x: {
},
marks: [
Plot.tickX(ReportData,
{
x: "Purchased At Date",
y: "Commerce Name",
stroke: "Commerce Name",
strokeWidth: 1
})
],
height:400,
width:800,
marginLeft: 150,
marginBottom: 150
})
