I was making a movie for the code I have written in C using gnuplot. I have=
 to set many rectangles in the window at each instant of time (from x1,y1 t=
o x2,y2) and I have this configurations in different files.. config_00.txt,=
 config_10.txt, config_20.txt, etc.. at times 0,10,20, etc.. each of which =
have 4 columns x1,y1,x2,y2. How can I do this ?. If my file was storing onl=
y x and y, and If i need to draw a line only I could have written "plot 'co=
nfig_10.txt' only.. But here that's not the case.. I need to scan each line=
 of each file and set objects at possitions that line does say.. I saw some=
thing like "call" in gnuplot.. but I could't understand please help..  I ma=
y write a program to scan each files(which stores configuration at differen=
t times) and set objects.. then unset again set from next file but it looks=
 tedious.. for ploting data points in a file with x,y columns we can just s=
ay plot "file.txt" u 1:2... but i was asking whether there is something lik=
e "from file_10.txt set object rectangle from $1,$2 to $3,$4

After setting those objects, to see the configuration i used to plot someth=
ing like plot 0.. so gnuplot shows me my configuration
