List of Points
Axiom has the ability to create lists of points in a two dimensional
graphics viewport. This is done by utilizing the
GraphImage and
TwoDimensionalViewport
domain facilities.
In this example, the makeGraphImage
takes a list of lists of points parameter, a list of colors for each point
in the graph, a list of colors for each line in the graph, and a list of
numbers which indicate the size of each point in the graph. The following
lines create list of lists of points which can be read be made into two
dimensional graph images.
First we make a list of points
Then we select pairs of these points which represent the endpoints of lines.
Next we set the point color and size, and the line color for all components
of the graph.
Now the graph image is created and named according to the component
specifications indicated above. The
makeViewport2D command then
creates a two dimensional viewport for this graph according to the list
of options specified within the brackets.
The makeViewport2D command takes a
list of options as a parameter. In this example the string "Lines" is
designated as the viewport's title.
