this is my code:

In[76]:= sekprav = 
 Import["C:\\Users\\Mitja\\Documents\\prakiktum 5 in \
6\\sipanipravokotno.txt", "Table"]

Out[76]= {{0, 22}, {1, 25}, {2, 20}, {3, 23}, {4, 26}, {5, 19}, {6, 
  29}, {7, 26}, {8, 19}, {9, 23}, {10, 20}}

In[77]:= tsekprav = 
 Transpose[{sekprav[[All, 1]], sekprav[[All, 2]]/10}]

Out[77]= {{0, 11/5}, {1, 5/2}, {2, 2}, {3, 23/10}, {4, 13/5}, {5, 19/
  10}, {6, 29/10}, {7, 13/5}, {8, 19/10}, {9, 23/10}, {10, 2}}

In[78]:= Show[ListPlot[tsekprav, PlotStyle -> Black], 
 Plot[Mean[tsekprav[[All, 2]]], {x, 0, 10}, PlotStyle -> Red], 
 PlotLabel -> 
  "Sipanje sekundarnih žarkov - pravokotno (\[CapitalDelta]t=10s)", 
 Axes -> {False, True}]

And the problem is, that I would somehow like to have the number on the mean value written on the graph. So is there perhaps a way I could create only ONE read Ticks at the mean value and also write the value next to it... I know about the Epilog, but I am just curious for any other options.

Thanks for all the help!

tsekprav = {{0, 11/5}, {1, 5/2}, {2, 2}, {3, 23/10}, {4, 13/5}, {5, 19/10}, {6, 29/10}, 
            {7, 13/5}, {8, 19/10}, {9, 23/10}, {10, 2}};

ListPlot[tsekprav, PlotStyle -> Black, 
 Ticks -> {Automatic,
          {{#, Style[#, Red, 20], {0, -.02}, Directive[Red, Thick]}&@Mean[tsekprav[[All, 2]]]}}]

enter image description here

ListPlot[tsekprav, PlotStyle -> Black, 
 Ticks -> {Automatic, {{#, Style[#, Red, 20], {0, -.95}, 
                       Directive[Red, Thick, Dashed]} &@Mean[tsekprav[[All, 2]]]}}]

enter image description here

what if I wanted to keep the original Ticks and only add the red one?

lp1 = ListPlot[tsekprav, PlotStyle -> Black]; 
ListPlot[tsekprav, PlotStyle -> Black, 
 Ticks -> {Automatic, Join[Last[Ticks /. AbsoluteOptions[lp1]], 
                        {{#, Style[#, Red, 20], {0, -.02}, 
                          Directive[Red, Thick]} &@Mean[tsekprav[[All, 2]]]}]}]

enter image description here

Note: As noted by @SquareOne in comments, AbsoluteOptions does not work as expected in V10.

Or, more conveniently, Epilog:

ListPlot[tsekprav, PlotStyle -> Black, 
 ImagePadding -> {{40, 0}, {20, 0}}, PlotRangeClipping -> False, 
 Epilog -> {{Style[Text[#, {-.95, #}], Red, 14], 
             Directive[Red, Thick] , Line[{{0.5, N@#}, {-.5, N@#}}]} &@
            Mean[tsekprav[[All, 2]]]}]

  • $\begingroup$ Wow, that's nearly perfect. Just wondering, what if I wanted to keep the original Ticks and only add the red one? $\endgroup$ – skrat Nov 8 '14 at 9:37
  • $\begingroup$ @skrat, I updated with a couple of ways to add a styled tick to the existing ones. $\endgroup$ – kglr Nov 8 '14 at 10:26
  • $\begingroup$ The solution with AbsoluteOptions won't work in version 10 (this function is broken $\endgroup$ – SquareOne Nov 13 '14 at 23:15
  • $\begingroup$ Thank you @SquareOne, i will update with a note. $\endgroup$ – kglr Nov 13 '14 at 23:18
