 394  <div style="font-weight:bold;font-family:arial;font-size:85%;">Description</div>This can be used when more advance formatting of the axis labels are required. For example this could be used to format numbers with space or commas betwen the '1000.
 395  <p>
 396  The callback routine is called with one argument, the current number to be displayed and should return the number to be displayed.
 397  <p>
 398  For simple formatting use SetlabelFormat() to specify a printf() style formatting string.
 399  <p>
 400  The callback function specified should can either be a 
 401  global function or a class method, for example
 402  
 403  <pre>
 404  $SomeClass = new SomeClass(...); 
 405  ... 
 406  $g->SetXLabelFormatCallback(array($SomeClass,'xLabelCallback'));
 407  </pre>
 408  <p>
 409  There is, however, one caution. Any $this data used within LabelFormatCallbackInDerivedClass MUST BE SET BEFORE SetLabelFormatCallback is invoked! it appears that $this is bound/copied when SetLabelFormatCallback is invoked. Only $this data defined at that time is available within the callback function! Likewise, modifications to $this data AFTER SetLabelFormatCallback have no effect since the $this object used by the callback function has already been bound/copied.
 410  <p>
 411  The same issues obtain when the callback function is in a seperate class!
