autoOutput - Pick up from the cache render it using the appropriate method

This function allows you to retrieve a cached object and send it automatically to either the user web browser or in a flat file. Basically it will works the same way than where you‘ll call the autoOutput() function from the pChart class.

Calling this function

ID is the unique ID affected to this object.
Destination is the path to a file where the picture will be saved (if saving to disk is choosen).

Sample script

 /* Include all the classes */ 

 /* Create your dataset object */ 
 $myData = new pData(); 
 /* Add data in your dataset */ 

 /* Create the cache object */
 $myCache = new pCache();

 /* Compute the hash linked to the chart data */
 $ChartHash = $myCache->getHash($myData);

 /* Test if we got this hash in our cache already */
 if ( $myCache->isInCache($ChartHash))
   /* If we have it, get the picture from the cache! */
   /* Create a pChart object and associate your dataset */ 
   $myPicture = new pImage(700,230,$myData);

   /* Choose a nice font */

   /* Define the boundaries of the graph area */

   /* Draw the scale, keep everything automatic */ 

   /* Draw the scale, keep everything automatic */ 

   /* Do some cosmetics */
   $myPicture->drawText(10,13,"Test of the pCache class",array("R"=>255,"G"=>255,"B"=>255));

   /* Push the rendered picture to the cache */

   /* Render the picture */
