Basically, if you do as Danl says, you'll be fine, but I always think of "bias voltage" as the difference in voltage (with respect to ground) between the grid and the cathode. The grid V always has to be negative wrt the cathode V. So that family of parallel curves you posted will be at progressively more negative bias voltages (0, -2, -4, etc). The more negative the bias voltage, the more the tube is turned off, and vice-versa. Whereas, the "cathode voltage" is just one parameter needed to calculate bias voltage. For some, this may be a matter of semantics.EDIT: This was meant to appear below Vinnie's response to Danl. Sorry.
