aligning inset plots in gnuplot

Question

How do I align an inset plot in multiplot so that the right and top frames of both plots coincide so that I get something like in this plot:

I tried to read the documentation on coordinates but I do not understand that at all and thus I cannot properly set origin and size.

Answer 1

You specify the size of the inset relative to the main figure using set size, and then move its bottom left corner using set origin so that the top right corner is at (1,1). For example,

set multiplot

plot exp(-x)            # plot main figure

set size 0.6, 0.5       # set size of inset
set origin 0.4, 0.5     # move bottom left corner of inset
plot cos(x)             # plot inset

unset multiplot

gives

Of course you will have to adjust tick labels and legends to avoid overlaps in the composite figure.
