Multigraph problem

After my SD card with a nearly perfect working emoncms died I installed the ready-to-go image on a new SD card, that's a really fast solution but I've got a problem, visualisations isn't working as expected when I tried to defina a multigraph.

So I tried to update it to a new version using git clone (emoncms and raspberrypi module). There multigraph seems to  work but not with the first multigraph generated. The multigraph 1 doesn't allow to add any value, multigraph 2 works as expected.

Any ideas?
