Help sought with research project!!

[imported_unknown]

I am doing a research project with children. I am collecting exercise data using 2 machines with different propietary software. One displays their activity data in 60 cell rows representing 1 hour of exercise. The other displays heart rates in 10 cell rows representing 10 minutes of data. I want to display both parameters in a series of graphs representing 1 hour of data. When I try to graph 1 hours worth of heart rate data I get 6 x 10 minute graphs. How can I convert the 6 rows x 10 cells of heart rate data into 1 row x 60 cells? Is there another way to obtain my graphs? Any advice would be appreciated.
