This makes perfect sense! Thank you, Rohit!

Yes, there is a way, but it is counterintuitive, change 5, 5 to 5, -5.

f2 = Graphics3D[{Black, PointSize[0.02], 
         Point[{5, -5, Log[5] + Log[5] + .1}], 
         Text[Style["X", 12], {5, -5, Log[5] + Log[5] + .6}]}, Axes -> True]

Hi Rohit, Thanks for your reply. When I Graphics3D I cannot combine fig1 and fig2 because fig1 has a reverse axis. I use ScalingFunctions -> {None, "Reverse"} in fig1. So, the following code places X outside the surface plot.

fig1 = Plot3D[Log[a] + Log[b], {a, 1, 10}, {b, 1, 10}, 
  ScalingFunctions -> {None, "Reverse"}]; f2 = 
 Graphics3D[{Black, PointSize[0.02], 
   Point[{5, 5, Log[5] + Log[5] + .1}], 
   Text[Style["X", 12], {5, 5, Log[5] + Log[5] + .6}]}];
Show[fig1, f2]

Is there a way to make Graphics3D work with a reverse axis or is there a way to modify labels in ListPointPlot3D? Thank you so much in advance. Cuneyt

Hi Cuneyt,

Yes, the easiest way is to add an offset. Rather than using ListPointPlot3D you could use Graphics3D so you have more control over the point and label.

f2 = Graphics3D[{Black, PointSize[0.02], 
         Point[{5, 5, Log[5] + Log[5] + .1}], 
         Text[Style["X", 12], {5, 5, Log[5] + Log[5] + .6}]}];

Show[fig1, f2]
