[rrd-users] RRD NaN Problem / Zero Values

First question:

I'm having a problem with my rrd-application:

I use TCL to read a logfile, and if there something in it, I want to 
update it into my RRD.

So I don't have a fixed update interval, sometimes I've got 10 entries / 
minute, sometimes 1 entry per day.

The graph shows when we had how many actions.

The RRD is set to:
create c.rrd --step 10 --start 1068908953 DS:unknown:GAUGE:120:0:U 
RRA:AVERAGE:0.99999:30:400 RRA:AVERAGE:0.99999:180:400 
RRA:AVERAGE:0.99999:720:400 RRA:AVERAGE:0.99999:8640:800

(I'm using 0.99999 because I thought I will get less NaN's. )

Is this the wrong way how to store data like I have? Any suggestions?
2nd question:
Is there a way to fill in a time range with Zero Values? I can do it 
with a for-loop, but this takes *a lot* of time.
I didn't see any solutions for this.

Sorry, I’m (still) not good in English...
