data being stored but cannot visualize

Hi,

I have set up a minimal raspbian install and went through with an

sudo apt-get install emoncms

I have a backup data from another server which i loaded in mysql, and even though the inputs and feeds loaded correctly and the data is being stored (i can see it on the input tab that the data is arriving) but when i go to vis i can't see any data..

I think i'm missing a module or something.. what could be wrong?

thanks
