How do I get it to graph and count (time / distance) for walking and biking?
an amazing likeness
You'll want to go to your log and use the Reports. Make a new Graph which has the attributes (activities, dates, etc) you want. Then save it and it's yours to use. In summary:
Training Log -> Reports -> New Graph (or New Report) -> fill out selection/filters (which activity, which dates, group by) -> click Graph (Report)
Choosing my words carefully has never been my strength I've been known to be vague and often pointless
