int ProfMon::Xindex (  int  channel  )  [static]
 

Get the index into the wire data block for the given wire channel for either X or Y views. The channels are numbered 1-44, indices are confined to be [0-95] but don't fill the range completly. Negative index is returned if a bad channel is passed.
