title: Core-Plot how to pack data
body: <p>I was wondering how I need to prepare the data so it is ready for core-plot.</p>
  
  <ul>
  <li>one line per year </li>
  <li>dayOfYear in the x-axis </li>
  <li>value on the y-axis</li>
  </ul>
  
  <p>My x-axis has 366 points (Each day of the year). At the moment I have a dictionary that looks like this</p>
  
  <pre><code> 2009 (year) =     {
          151 (dayofyear) = 5 (value);
          192 = 25;
          206 = 5;
          234 = 20;
          235 = 20;
          255 = 20;
          262 = 10;
          276 = 10;
          290 = 10;
          298 = 7;
          310 = 1;
          338 = 3;
          354 = 5;
          362 = 5;
      };
      2010 =     {
          114 = 7;
          119 = 3;
          144 = 7;
          17 = 5;
          187 = 10;
          198 = 7;
          205 = 10;
          212 = 10;
          213 = 20;
          215 = 5;
          247 = 10;
          248 = 10;
          256 = 10;
          262 = 7;
          264 = 10;
          277 = 10;
          282 = 3;
          284 = 7;
          47 = 5;
          75 = 7;
          99 = 7;
      };
      2011 =     {
          260 = 10;
      };
  </code></pre>
  
  <p>I think core-plot needs an array doesn't it? How would you pack this to be the most efficient?</p>
