# Combine a List of Plots: Using MapThread with Show [closed]

I have a list of graphics

p1 = Plot[x Sin[x] - 1, {x, -2.5, 2.5}]
p2 = Plot[Evaluate[D[x Sin[x] - 1, x]], {x, -2.5, 2.5},PlotStyle -> Red]
ListNew = {p1, p2};


I can use Show to combine them:

Show[p1,p2]


I can also use MapThread if I understand correctly here:

MapThread[f,{x1,x2}] = f[x1,x2]


But I dont understand why using MapThread with Show wont work?

MapThread[Show,ListNew]

• You want Apply not MapThread. – b3m2a1 Aug 12 at 23:07
• MapThread is for mapping a multivariate function over multiple lists of arguments, not for applying such a function to a sequence of arguments. – m_goldberg Aug 13 at 1:25

 MapThread[f,{x1,x2}]
