I want to plot a function f[x] so that argument x would go from larger x1 to smaller x2. However 

Plot[Log[x], {x, 2, 0.1}]

draws the same picture as 

Plot[Log[x], {x, 0.1, 2}]

enter image description here

See Figure below. I need x running from 2 on the left to 0.1 on the right.

Try this: 

 Plot[Log[2 - x], {x, 0.1, 2}, 
Ticks -> {Table[{i, 2 - i}, {i, 0.1, 2, 0.2}], Automatic}]

with the following effect:

Have fun!

    $\begingroup$ Then you should explain more clearly, what are you after, and, maybe, give a drawing (a hand-drawing?). $\endgroup$

  • $\begingroup$ Actually, your solution would be fine if Ticks->{..} will completely emulate automatically gemerated ticks including shorter intermediate ticks which go withoul labels. $\endgroup$

    $\begingroup$ Look, Igor, This was not the main question of your post. This you can easily do by hands. Just do construct the ticks of your liking. This is trivial. I only gave a direction, where you can go. $\endgroup$
