Here's a simple plot:

load 'plot'

pd 'reset;color red'

pd 'type marker;markersize 2'

pd <"1|:0 0,:10 10

pd 'show'


1. The above code plots two points, one at 0,0 and one at 10,10. How can I
plot just ONE point? The following code shows NO dots at all:

load 'plot'

pd 'reset;color red'

pd 'type marker;markersize 2'

pd <"1|:10 10

pd 'show'


Also in the first example, how can I put a text legend beside the dot at
10,10? I just want a single ASCII number there beside the 10,10 dot.
