Can I plot graphs in a day scale? (no replies)

Hi Folks,

I'm not sure if I misconfigured my piwik server or if I'm missing something here, but I can't figure a way to plot evolution graphs (Visitors over Time, Evolution over Period) in a day by day scale (1-30), only in a month by month bases (1-12).

Can piwik plot those graphs in a daily scale?

Thanks in advance,

Eric
