Hi i am traying to get the values of the hourly rain, to put them on a graph like you can see in the image

I want to get the values from 00:00 to the current time.
I have search the cumuluswebtags.txt and didn´t find nothing that gives me the rain on one hour, only see the <#rhour>.
sorry for my bad english.

Cumulus doesn't store any data like that. You could do it with the <#RecentRainToday> web tag, using the 'h=' parameter, but you're going to have to do some calculating yourself (in Javascript or whatever).

For example, if it is currently 16:00, and you want the rain that fell between 14:00 and 15:00, then you would subtract <#RecentRainToday h=2> from <#RecentRainToday h=1> (i.e. subtract the total at 14:00 from the the total at 15:00 to give the amount between 14:00 and 15:00).

hi,
I have ben trayng what steve tell and year are some values
$time = "21:05 on 05 Março 2013";
$rfall = "51,9"; // the total rainfall so far today

$rain1hour = '46,5'; //Chuva 1 hora atras
$rain2hour = '45,0'; //Chuva 2 hora atras
$rain3hour = '44,7'; //Chuva 3 hora atras
$rain4hour = '44,7'; //Chuva 4 hora atras
$rain5hour = '44,1'; //Chuva 5 hora atras

well a don´t understand how it works, I'm confiused,
the $rain1hour-$rain2hour=1,5mm this value shoulbe time 20:00 to 21:00 corret?
or that value is 19:00 to 20:00
wen the rain today is 51.9

If it's 21:05 now, then <#RecentRainToday h=1> is the total at 20:05, i.e. one hour ago. So $rain1hour-$rain2hour=1,5mm is the amount that fell between 19:05 and 20:05.

Very good. But - the four totals for 15/16/17/18 add up to 5.1, and it says at the top that you've had only 3.9 today?
