These plots do not show the first tick label on the left:

Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-.41, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-.42, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-.43, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-.44, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-.51, 1.05}, None}]

But these work fine:

Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-1.41, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-1.42, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-1.43, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-1.44, 1.05}, None}]
Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-1.51, 1.05}, None}]

Am I missing something, or possibly a bug?

    $\begingroup$ Mathematica will suppress tick labels that would obscure an axis line if drawn. In such cases you will see the tick but not the label. $\endgroup$

  • $\begingroup$ @m_goldberg Is it possible to switch off suppression of such tick labels? $\endgroup$ Apr 29 '15 at 0:14

The Problem is because for Ticks close the origin and with the current image size, the ticks place extend into the positive side of the axes.

Check this:

Plot[Sin[x], {x, -4, 4}, 
 Ticks -> {{#, "Z = " <> ToString@#} & /@ {-.51, 1.05}, None}, 
 ImageSize -> 600]
