In an isometric drawing, lines in the direction of the pricipal axes (X, y, and Z) are drawn true lenght at 30 deg from the horizontal or vertically. An isometric projection on the other had is the projection of a 3D object from a vantage point that shrinks the geometry such that lines parallel to the principal axes are scaled by a factor of sqrt(2)/sqrt(3) = 0.816... (the length from corner to opposing corner of a side of a unit cube divided by the lengh diagonal of the cube). This number is close to the ratio of your plotted scale vs full scale.
Try a scale factor of (1/0.618) * (1/20)
