Class ComparativeScatterPlot

source code

object --+
         |
        ComparativeScatterPlot

Display a scatter-type plot comparing two different kinds of info.

Attributes;

o display_info -- a 2D list of the information we'll be outputting. Each
top level list is a different data type, and each data point is a two-tuple
of the coordinates of a point. So if you had two distributions of points,
it should look like:

display_info = [[(1, 2), (3, 4)],
                [(5, 6), (7, 8)]]

if everything is just one set of points, display_info can look like:

display_info = [[(1, 2), (3, 4), (5, 6)]]

__init__(self, output_format='pdf')
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

draw_to_file(self, output_file, title)

source code  
Write the comparative plot to a file.

Arguments:

o output_file - The name of the file to output the information to,
                or a handle to write to.

o title - A title to display on the graphic.

_set_colors_and_shapes(self, scatter_plot, display_info)

source code 

Set the colors and shapes of the points displayed.

By default this just sets all of the points according to the order of colors and shapes defined in self.color_choices and self.shape_choices. The first 5 shapes and colors are unique, the rest of them are just set to the same color and shape (since I ran out of shapes!).

You can change how this function works by either changing the values of the color_choices and shape_choices attributes, or by inheriting from this class and overriding this function.
