Screen > simple graph: change time scale from 1h to 1 day?

[sean]

Hi,

I've created a screen with several "simple graphs" linked to data collected on hosts. In the definition of the graphs in the screen I can change size, alignment - but I would like to change the scale, i.e. the graphs should show be the last 24h, not the last hour.

How can I do this?
I'm using version 1.4.2.

Thanks in advance,
