/**
* Set the axis padding for a specified position.
*
* The axis padding is padding "inside" the plotarea (i.e. to put some space
* between the axis line and the actual plot).
*
* This can be specified in a number of ways:
*
* 1) Specify an associated array with 'left', 'top', 'right' and 'bottom'
* indices with values for the paddings. Leave out 2nd parameter.
*
* 2) Specify an overall padding as the first parameter
*
* 3) Specify the padding and position with position values as mentioned
* above
*
* Normally you'd only consider applying axis padding to a category x-axis.
*
* @param mixed $value The value/padding
* @param mixed $position The "position" of the padding
