Is there any way to mark a specific line on the Plot3D graph in Log scale. My initial plot is: `
Plot3D[(y/(0.5*y + 2*x)), {x, 1/10^10, 1/10^3}, {y, 0, 4.5/10^6},
ScalingFunctions -> {"Log", "Log", None},
ColorFunctionScaling -> True]
` If is is not in Log scale,I know I can use ParametricPlot3D and use Show to overlay them together. But once I plot it in Log scale, ParametricPlot cannot show in Log scale. What I would like to have is something like this:
Plot3D[(y/(0.5*y + 2*x)), {x, 1/10^10, 1/10^3}, {y, 0, 4.5/10^6},
ScalingFunctions -> {"Log", "Log", None},
ColorFunctionScaling -> True,
MeshFunctions -> Function @@@ {{{v, u}, v^3}}, Mesh -> 1,
PlotPoints -> 100, Ticks -> Automatic]
` However, since the MeshFunctions does not give a meaningful idea of what does the line stands for. Is there a way to just specify the X value to plot a line on that surface? Thanks!
