title: d3.js - starting and ending tick
body: <p>I am building an area graph in d3.js.</p>
  
  <p>For my y axis, I want to use a linear scale that extends from the minimal value to the maximal value of the data represented in the graph.</p>
  
  <p>Using</p>
  
  <pre><code>y = d3.scale.linear().range([height, 0]),
  yAxis = d3.svg.axis().scale(y).orient("left")
  </code></pre>
  
  <p>d3 shows ticks only for multiples of 10000. </p>
  
  <p>I would like also to see ticks for the starting and the ending value. Is this possible? How?</p>
