Dislin plotting library

Sorry for a lazy question, can Dislin show plot in real time?
I mean if I run a program, it continuously output pairs of (x,y) to a say, txt file, can Dislin plot (x,y) in real time from the txt file?
Or do I have to wait until all the (x,y) has been generated, then use Dislin to plot them?

By the way, the topic by @Beliavsky seems may of help,
