Fix gps lk unlk plotting - coloring, positioning label

closes #109 (closed)

• Adjust relative position between GPS Lk/Unlk and GPS Clock Power, separate data of GPS to 2 groups for sample numbers display
• From different plots, give different colors that match with plot and different position for displaying sample numbers.
