I think this is possible, but I don't see how to do it.
I'd like to specify different scaling for each of the x, y and z coordinates, and have this apply to everything that is plotted afterwards. For example, I might want to apply scaling of (1, 2, 3) to (x, y, z); then a line drawn from (0,0,0) to (1,1/2,1/3) would be rescaled so that it appeared to go the same distance in all three coordinates.
I see in the graph3.asy code things like
pic.scale.x.T(x);
which suggests this is being used, but I don't see where the scale is set.

Thanks for the suggestion, but that rescales ticks in my graph axes too, so it doesn't look good.
Some background: I'm generating Asymptote code automatically, so I can rescale things before sending them to Asymptote. The problem then is with axes, which show rescaled numbers rather than
the original numbers.
So maybe my question should have been: How do I generate an axis with tick locations given in a real[] array, and the labels for those ticks given in a string[] array?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I have a partial answer to my revised question. I can create a function to rescale tick values before formatting them; this is sufficient for my needs.
Specifically: assuming the points are rescaled before Asymptote sees them, I can use code like

If you're willing to settle for scaling everything drawn so far rather than everything potted afterwards, you could use

Specifically: assuming the points are rescaled before Asymptote sees them, I can use code like
ticklabel RGLScale(real s) { return new string(real x) {return format(s*x);}; } xaxis3(axis=YZEquals(y=-2.282996, z=-2.406974), xmin=-2.987038, xmax=1.257171, ticks = Ticks3(1, Ticks = new real[] {-2.7418094170615, -1.82787294470766,-0.913936472353832,0,0.913936472353832}, ticklabel = RGLScale(0.00547084)));and the ticks end up displayed on the original scale: -0.015, -0.01, -0.005, etc.
