    1818 * The underscore is a more visual representation of a space (0x20)

    20  * <timestamp> is in ISO8601 format YYYY-MM-DDTHH:MM:SS. The utility convert_date_iso_to_int.py (in the same SVN repository) can be used to convert it to YYYYMMDDHHMMSS, that is, an integer value chronologically ordered that can be used as an input value for gnuplot).
     20 * <timestamp> is in ISO8601 format YYYY-MM-DDTHH:MM:SS. The utility convert_date_iso_to_epoch.py (in the same SVN repository) can be used to convert it to YYYYMMDDHHMMSS, that is, an integer value chronologically ordered that can be used as an input value for gnuplot).

    2222 * <Apache errors> can sometimes be -1. It means either that no data was available, or that there was no entry in the error_log file for the 10-minute sampling period. The distinction is not made because 1) it will require to add more code (I let you guess all the cases that may occur); 2) once plotted, the average human will not mage any difference between -1 and 0 (specially when values as large as 1000 are drawn).
