I made a gnu script to plot graph
my script
set size square
plot "./points.dat" using 1:2 pt 7 ps 1
replot "./circle.dat" using 1:2:3 with circles
points.dat
1.000000 -1.000000
-1.000000 1.000000
-1.000000 -1.000000
1.000000 1.000000
circle.dat
0.000000 0.000000 1.414214
according to data-points all points must be in circle but graph shows points outside the circle
Can someone please help me .
