# Custom ticks failing with Frame [closed]

I know I can manipulate ticks:

 Plot[PDF[NormalDistribution[0, 1.5], x], {x, -7, 7},
Ticks -> {{
{-6, "-6σ"}, {-5, "-5σ"}, {-4, "-4σ"}, {-3, "-3σ"}, {-2, "-2σ"}, {-1, "-σ"},
{1, "σ"}, {2, "2σ"}, {3, "3σ"}, {4, "4σ"}, {5, "5σ"}, {6, "6σ"}
}}]


But the ticks disappear when I add Frame -> True. What am I doing wrong?

Nothing wrong as such... only for Frame you need the FrameTicks option (to add some spice see another way to get your ticks):
xticks = {#, StringReplace[ToString[# σ], " " -> ""]} & /@Range[-6, 6];

• Typographic note. I suggest replacing StringReplace[ToString[# σ], " " -> ""] with StringReplace[ToString[# σ], " " -> "\[VeryThinSpace]"]. The difference is subtle, but inserting a very-thin-space really makes the tick labels look better. – m_goldberg Sep 22 '13 at 8:51
