Charts not visible

Charts with time, heart rate, cadence, etc. - are not visible - what's wrong ?

The same for me, what´s wrong

Just cadence with me, and its missing in player.

Try Google chrome

heart speed and cadans aint working in google chrome

heart and speed are working (in mozilla firefox)
Cadans isn't

Cadence is missing for me... in both Firefox and IE. If I expand the graph for Cadence the vertical axis just says undefined. I can get graphs for speed, heart rate, elevation & temperature OK. Its disappeared for much older records as well so it must just be a display issue.
