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