Proper way to draw gridlines

Question

Okay, I\'m starting to get a little more familiar with D3 but am still a little hazy on some things. I\'m now trying to draw grid lines but am realizing that I may be hackin

Answer 1

You could just use innerTickSize, instead of tickSize:

            var xAxis = d3.svg.axis()
                    .scale(xScale)
                    .orient("bottom")
                    .ticks(1)
                    .innerTickSize(-h);
