* more complex function. An example could be (not very applicable though) if one would
* need for values to be displayed on the reverse order, i.e. 1234 would be displayed as
* 4321, then this method can solve this by creating the function that converts the value
* and use the FunctionData datapreprocessor to make Image_Graph use this function.
