title: pChart example does not render x and y axis labels
body: <p>I am running the Line Graph example in the pChart website. </p>
  
  <p><a href="http://pchart.sourceforge.net/documentation.php?topic=exemple1" rel="nofollow noreferrer">http://pchart.sourceforge.net/documentation.php?topic=exemple1</a></p>
  
  <p>The rendered png file is missing the X and Y axis labels as well as the "January" "March" "April" labels. </p>
  
  <p>I ran phpInfo and verified that GD was supported. I am running with php5. </p>
  
  <p>Any thoughts on why the graph gets rendered by not the labels?</p>
  
  <p>Edit: I was able to show the Legend. I didn't not have the required Font directory. But the X and Y axis markers are still missing. by "Markers" i mean that the X axis does not show 1,2,3 ... 20 .. and the Y axis does not show 100us, 200us, ...600us. </p>
