void grLibSetUserValue

(Graph_t* br, UInt16 idx, void** uptr)

[OPTIONAL]:Sets the user defined information for a data point


[OPTIONAL]:Sets the user defined information for a data point

br - pointer to the data structure of the actual graph
idx - the index within the graph data where the information needs to be set in
uptr - any user defined data structure
NOTE: uptr can be a structure, integer or char * - anything as long as the developer allocates necessary memory and sets the values. this information can be "supplemental" or "additional" information for a specific graph point. Graph Lib routines as such do not use this value anywhere - this will be returned if a stylus tap on the screen falls within this graph point plot. The developer must decide what to do with this information. See app.c on how this is used.
