 305                  the percent sign in its name and will attribute minimum (0%) and maximum (100%)
 306                  values automagically, as well the ¨%" sign to graph units.
 307
 308                 3) OTOH, if the counter is "absolute", you'll have to provide the following
 309                  the counter unit - that is, the dimensions of the counter you're getting. Examples:
 310                  pages/s, packets transferred, etc.
 311
 312                 4) If you want, you may provide the minimum and maximum values to expect. They aren't mandatory,
 313                  but once specified they MUST have the same order of magnitude and units of -w and -c; otherwise.
 314                  strange things will happen when you make graphs of your data.
