Hi Oliver, Various possibilities here: If you just want to quickly know the maximum value shown in the plot you may select the plot, press shift-period and move the cursor to the highest point in your plot. The maximum will be in the tooltip. Second possibility is to examine the graphics commands underlying the plot. You can see them if you use FullForm. You have to delve deep for the nested data you need, but you can get there. For example: (Plot[Sin[x], {x, 0, Pi}] // FullForm)[[1, 1, 1, 3, 2, 1, All, 2]] // Max Third possibility is to use MaxValue or Maximize on the function you plotted using the plotrange as constraint: MaxValue[{Sin[Cos[5 x]], 0 <= x <= 2 \[Pi]}, x] Hope this helps.
