javascript - How to limit d3.svg.axis to integer labels?

Question

Is there any possibility to limit the number of d3.svg.axis integer labels displayed on the graph? Take for instance this graph. There are only 5 sizes here: [0, 1, 2, 3, 4]. However, the ticks are also displayed for .5, 1.5, 2.5 and 3.5.

Answer 1

You should be able to use d3.format instead of writing your own format function for this.

d3.svg.axis()
    .tickFormat(d3.format("d"));

You can also use tickFormat on your scale which the axis will automatically use by default.
