5.3 Including data within command scripts

It is also possible to embed data directly within Pyxplot scripts, which may be useful when a small number of markers are wanted at particular pre-defined positions on a graph, or when it is desirable to roll a Pyxplot script and the data it takes into a single file for easy storage or transmission. To do this, one uses the magic filename ­-­- and terminates the data with the string END:

plot '--' with lines
0 0
1 1
2 0
3 1
print "More Pyxplot commands can be placed after END"
