The emu_graph Widget

Here's a short demo of the emu_graph widget.

The code which generated the above plot is:

set testdata(1) {5.2427 1293.93 5.2477 1331.18 ... }
set testdata(2) {5.2427 2155.64 5.2477 2241.15 ... }
canvas .c -width 500 -height 400
pack .c 
emu_graph foo -canvas .c -width 400 -height 300
foo data d1 -colour red -points 1 -lines 0 \
	-coords $testdata(1)
foo data d2 -colour blue -points 0 -lines 1 \
	-coords $testdata(2)
