title: How to set custom labels on y axis
body: <p>I'm using the Google Chart API (not Google Image Chart) to create a line chart with dates on the x axis (bottom) and numbers on the y axis (left). I want to add an r axis (right) with string labels.</p>
  
  <p>If I understand the following page correctly, it's only possible to
  have strings on the major axis (x axis for line chart). The minor axes (y and r axes) only
  accepts continuous values (like numbers) and not discrete values (like
  strings).</p>

  <p>In Google Image Charts it is possible to work around this by assigning the string data to a value (say from 0 to 100) and assign custom string labels to the axis using the chxl parameter. This is especially easy if the data is evenly spaced.</p>
  
  <p>I've looked at the API reference but can't find anything similar when using the Google Chart API.</p>
  
  <p>Does anyone know if it's possible?</p>
  
  <p>Best regards,
  JP </p>
