Axes for SAGE 2D Graphics.

Set all axis properties and then add one of 
the following axes to the current (matplotlib) subplot:
add_xy__axes
add_xy_frame_axes
add_xy_matrix_frame_axes

_tasteful_ticks(self, minval, maxval)

source code


This function finds spacing for axes tick marks that are well spaced.
Were 'well spaced' means for any given min and max values
the tick spacing should look even and visually nice (tasteful).

add_xy_axes(self, subplot, xmin, xmax, ymin, ymax, axes=True, ticks=`'automatic'`, axesstyle=`'automatic'`, axes_labels=`['4ti2-20061025',` `'R-2.6.0',` `'atlas-3.7.37',` `'atlas-3.8.1',` `'a...`)

source code


\code{_add_xy_axes} is used when the 'save' method
of any Graphics object is called.

Additionally this function uses the function '_find_axes' 
from axis.py which attempts to find aesthetically pleasing
tick and label spacing values.

Some definitons of the parameters:

y_axis_xpos : "where on the x-axis to draw the y-axis"
xstep : "the spacing between major tick marks"
xtslminor : "x-axis minor tick step list" 
xtslmajor : "x-axis major tick step list" 
yltheight : "where the top of the major ticks go" 
ystheight : "where the top of the minor ticks go" 
ylabel : "where the ylabel is drawn" 
xlabel : "where the xlabel is drawn"

add_xy_frame_axes(self, subplot, xmin, xmax, ymin, ymax, axes_with_no_ticks=False, axes_labels=`['4ti2-20061025',` `'R-2.6.0',` `'atlas-3.7.37',` `'atlas-3.8.1',` `'a...`)

source code


Draw a frame around the perimeter of a graphic.

Only major tick marks are drawn on a frame axes.

If \code{axes_with_no_ticks} is true, then also draw 
centered axes with no tick marks.

add_xy_matrix_frame_axes(self, subplot, xmin, xmax, ymin, ymax)

source code


Draw a frame around a \code{matrix_plot}.

The tick marks drawn on the frame correspond to
the ith row and jth column of the matrix.
