Yesterday when running I thought a little more about correspondingmaps and graphs. Sadly enough I can't inventionship since I just discovered that this is already implemented on sporttracks 3 (screenshot 2). The good part then that this already is there for me to use and that I can explain this very easy without having to do my own drawings. For me this is good tools that i suggest Globalsat to implement when planning sports gym pro 2.0
If I click somewhere on my trail on the map to the right on the screenshot below, a little window pops up showing me time and distance (small improvement would be if the window would be a few cm to side and not right on top of where i click and if it would be possible to choose what info to display in the window.)
When I click the graphs to the left shows corresponding values depending on which graphs i have chosen.
And as you see on the screenshot below you can also highlight a stretch on your trail the corresponding graphs will give you start- and endvalues + in this case average tempo (it seems like) and change of altitude. If this also got displayed in a table it would be even nicer and even more nerdy
Peaks in tempo is not due to problems with gps but my dog taking toiletbreaks.
