Sure do.
It might help for a better understanding to look at some typical valve data sheet characteristic curves, most will show at least a set of anode family curves and sometimes a set of grid family curves but remember they are static curves eg: no anode load, as soon as an anode load is introduced everything changes, for that you need to draw a load line and if needs be a dynamic transfer curve, sounds high and mighty but it isn't and is simple enough to do.
A load line drawn on a set of anode family curves will tell you what the anode voltage and current should be for different grid bias voltages, the bias voltages given are normally in increments of 1 volt or at best 0.5 volt, obtaining the dynamic transfer curve from the anode family of curves will show what the anode current should be for any grid voltage from zero to cutoff.
Both RDH4 and Riders books show how to draw a load line and a transfer curve, doing it kinda takes you through the motions as to what's what, worth doing as a simple exercise.
