Modules: Using Plot #!N #!EC #!N #!N #!F-adobe-times-bold-r-normal--18* Plot #!EF creates
a 2-dimensional plot from x,y data. (Data Explorer expects the "positions"
component to contain the x-values, and the #!F-adobe-times-bold-r-normal--18* data #!EF component
the y-values. You can pass (import) a group of such fields
to #!F-adobe-times-bold-r-normal--18* Plot #!EF , which plots them as multiple lines.
You can also add data-point markers to the lines. #!N #!I0

program .../Plot.net. Two Image windows appear: one a color map of
elevation data for the southeastern United States; the other, a plot
of the elevations along the purple line shown in the color
map. (The #!F-adobe-times-bold-r-normal--18* Slab #!EF module extracts the elevation data along
the line, but #!F-adobe-times-bold-r-normal--18* Construct #!EF could have been used to
create the line and #!F-adobe-times-bold-r-normal--18* Map #!EF to map the elevation
data onto the line. Note that #!F-adobe-times-bold-r-normal--18* Compute #!EF is used
to extract only the x-component of the positions.) #!N #!I30 #!N
