You are using rrdtool as a graphing tool, and (wrongly) expect it to behave like that. It isn't, and it doesn't. There's plenty of documentation available which explains what's going on; look at the tutorials, the manual pages and my site. In short: rrdtool is _not_ a regular database and it is _not_ a tool to make fancy pictures. The data you are seeing is _not_ wrong, your expectations are. That "0.5" is the "XFF". "%8.0lf" is input for "printf", do a google search for "printf manual" if you don't know it. Output numbers are in scientific notation (1.0e2 = 10) and are not the same as input numbers because of normalization and consolidation (see my site).
