<div style="font-weight:bold;font-family:arial;font-size:85%;">Description</div>Specifies the horizontal and vertical alignment for the labels on the axis. The alignment specifies how the labels is adjusted relative to the tickmark.
<p>
Note that this is handled automatically but on some occasion there is a genuine need to override the automtic values. For example if the graph is rotated it might be necessary to adjust the alignment to get a visual acceptable label alignment.
<p>
Possible horizontal alignment are: 'left', 'center', 'right' <br>
Possible vertical alignment are: 'top', 'center', 'bottom' <br>

</table>
<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.
<p>
The callback routine is called with one argument, the current number to be displayed and should return the number to be displayed.
<p>
For simple formatting use SetlabelFormat() to specify a printf() style formatting string.
<p>
The callback function specified should can either be a
global function or a class method, for example
<pre>
$SomeClass = new SomeClass(...);
...
$g->SetXLabelFormatCallback(array($SomeClass,'xLabelCallback'));
</pre>
<p>
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.
<p>
The same issues obtain when the callback function is in a seperate class!
