and the normal grid lines in the window.

URL Base
-
URL Base is not actually a Ptplot option, rather it is used
by the form to improve readability. URL Base is the URL that
is prepended on to the File to plot value
If (NONE) is selected in File to plot, then
URL Base is ignored.
-
File to plot
- A listbox consisting of the file to plot. Since this is
an applet, we can only plot files from the server. In a future version,
it might be possible to submit files to the server to be plotted
if
(NONE) is selected, then File to plot
and URL Base are ignored.
