d3 tick marks on integers only

Question

I have a d3 bar chart whose values range from 0-3. I would like the y-axis to only show integer values, which I can do by

var yAxis = d3.svg.axis().scale(y).         


        

Answer 1

You can programatically set the number of ticks to data.length - 1 (this solves the issue you were having for small numbers of ticks as well)

var yAxis = d3.svg.axis()
    .scale(y)
    .orient("right")
    .tickFormat(d3.format("d"))
    .ticks(data.length - 1)
