This is a quirk of the RRDtool autoscaling functions. Since you dont have the extended option 'rigid', and you are in 'scaled' mode, RRDtool is picking the range for the Y-axis to be something thats a round number and is greater than the values in the graph. The top example has values of a certain magnitude, and just over 10xxxx so the scaling functions pick 20xxxx as being the best value to use (maybe 15xxxx would have been better though). Nothing you can do about this, other than to use 'unscaled' mode and/or set the extended option 'rigid' to fix the Y-max to be MaxBytes. If using routers2 2.20beta4 you might try 'altygrid=y' in the routers2.conf to switch RRDtool to (globally) use the alternative calculations but I doubt this will help much and may cause other problems Steve |

Hello Steve , The combination of ... routers.cgi*Options[_]: rigid routers.cgi*UpperLimit[$Entity]: MaxByte+1M Works flawlessly . Thank you . JimL |
