Detailed Description

Draw a pair of intersecting x-y axes.

Axes(xmin, xmax, ymin, ymax, atx, aty, xticks, xminiticks, xlabels, xlogbase,
yticks, yminiticks, ylabels, ylogbase, arrows, text_attr, attribute=value)

xmin, xmax               required       the x range
ymin, ymax               required       the y range
atx, aty                 default=0, 0   point where the axes try to cross;
                                        if outside the range, the axes will
                                        cross at the closest corner
xticks                   default=-10    request ticks according to the standard
                                        tick specification (see help(Ticks))
xminiticks               default=True   request miniticks according to the
                                        standard minitick specification
xlabels                  True           request tick labels according to the
                                        standard tick label specification
xlogbase                 default=None   if a number, the x axis is logarithmic
                                        with ticks at the given base (usually 10)
yticks                   default=-10    request ticks according to the standard
                                        tick specification
yminiticks               default=True   request miniticks according to the
                                        standard minitick specification
ylabels                  True           request tick labels according to the
                                        standard tick label specification
ylogbase                 default=None   if a number, the y axis is logarithmic
                                        with ticks at the given base (usually 10)
arrows                   default=None   if a new string identifier, draw arrows
                                        referenced by that identifier
text_attr                default={}     SVG attributes for the text labels
attribute=value pairs    keyword list   SVG attributes for all lines
