[rrd-users] RRDTool Newbie needs help

[Tony Krsulic]

Below is a windows batch file I created. 
There is an app that will pass me data as often as every second.. for
items like  how many customers are currently waiting for assistance.
 
I believe I have the create line correct to expect data update every
second, and if I get it correctly in my mind, will get one hours worth
and then will round robin back to start of dbase and start collecting
next hour's worth? I set it for gauge/last because I don't want
averaging etc during the hour.
 
The graph though shows 08:00 through 09:00 and values 0.0 through 1.0
It's just a grid devoid of any actual plotted lines showing any data,
and I don't see why it's only ranging from 0.0-1.0  when the dummy data
values I'm putting in are 1 through 4. 
 
I've been gogling and trying various things, but so far I just don't
have a grasp of this yet.. help?
