An option to generate grid lines #81
Description
This is another frequent pattern:
svg.append("g")
.attr("transform", `translate(${marginLeft},0)`)
.call(yAxis)
.call(g => g.selectAll(".tick line").clone()
.attr("x2", width - marginLeft - marginRight)
.attr("stroke-opacity", 0.1))It’d be nice if this were an option you could pass to the axis, especially for transitions. Note that you’ll need to tell the axis how long the grid lines need to be (width - marginLeft - marginRight).
