Dear Alex,
yes, this is possible. You can just make a replot with your new data. If you have to delete the old data
set before, you can do it by plotting it again in background color, or you can delete the contents of an axis
system with 'axsers'. If a new scaling is necessary, you can erase the whole page with 'erase' and setup
a new axis scaling.
The graphical output in Dislin is buffered. If you want to see a plot output directly on the screen, you have to
call the routine 'sendbf' directly after the plot command.
With best regards,
Helmut
