In the new D3js version (version 3 onwards), when you create a chart axis via d3.svg.axis() function you have access to two methods called tickValues and tickFormat which are built-in inside the function so that you can specifies which values you need the ticks for and in what format you want the text to appear:

var formatAxis = d3.format("  0");
var axis = d3.svg.axis()
        .scale(xScale)
        .tickFormat(formatAxis)
        .ticks(3)
        .tickValues([100, 200, 300]) //specify an array here for values
        .orient("bottom");
