#3192 — Circle in multiplot not shown

Dear all,

I am using multiplot to plot 2 graphs under each other in a 0.6:0.4 ratio. Now I would like to highlight a certain part of the upper plot. I thought I would simply draw a circle on top which I explain in the corresponding text.

However, the circle is not shown and I am a bit lost. Is circle not valid in the multiplot environment?

Here is a sample gnuplot script with the circle is not shown:

reset

set terminal windows

set multiplot
set size   1.0,0.6
set origin 0.0,0.4
unset xlabel
set ylabel "YLabel1"
set format x ""

plot sin(x) t "1" w l lt -1 lw 2

set size   1.0,0.4
set origin 0.0,0.0
set xlabel "Index"
set ylabel "YLabel2"
set format x

plot 0.5*cos(x) t "2" w l lt 2 lw 2

set object 1 circle at 0,0 size 0.5

unset multiplot

pause -1

The only commands that actually draw to the screen are "plot" and
"splot".  All other commands, including "set", affect what will 
happen at the time of the next plot.  So you need to move your
"set object" command _before_ the last plot command.
