Hi
Some time ago somebody gave me a piece of code to plot the name of
vectors stored in a specific directory,
What I´m looking for is to plot all the points I have in the list
including those that are outside the screen and use the keyboard
arrows to move the points.
I´m using an HP48

This is what I have:

ERASE { # 0o # 0o }
PVIEW VARS LIST 1
SWAP HOME PLIST
VARS LIST 1 SWAP
HOME
START PICT SWAP
DUP PLIST RCL SWAP
DROP "." 1 HOME
GROB
IFERR GOR
THEN 3 DROPN
END
NEXT
START PICT SWAP
DUP PLIST RCL
(.3,.2) + SWAP "" +
1 HOME GROB
IFERR GOR
THEN 3 DROPN
END
NEXT 7 FREEZE

If the point is outside the screen the code just erases it and looks
for the next point

GROB
IFERR GOR
THEN 3 DROPN
END
NEXT

Please let me know if there is a solution.
Thanks

Rather than use:

"." 1 GROB GOR

might I suggest:

PIXON

Also, you can make a larger PICT environment with the PDIM command.
