3d data for triodes

    The spec sheets for triodes usually show two of the parameters i_b, e_b, e_c
    (plate current, plate voltage, grid voltage) on the x,y axes and then graph
    a number of curves corresponding to different values of the third parameter.
    That's kind of like a contour map. What I would like to know is whether anyone
    ever published, for any triode, a 3d version of the surface that is supposed
    to be described by that contour map. Alternatively, is there any repository
    anywhere of numerical data for any triode that gives much more refined
    information about its behavior, i.e. much higher resolution in the third
    parameter as well as lots of explicit coordinates for points on the various
    curves? That much data would allow one to make one's own 3d picture of the
    surface. Simply using the spec sheets is too error prone since it is hard
    to get good resolution of most of the points.

    Ignorantly,
    Allan Adler

    I doubt it. What purpose would it serve?
