Detailed Description

Draw an axis with tick marks along a parametric curve.

CurveAxis(f, low, high, ticks, miniticks, labels, logbase, arrow_start, arrow_end,
text_attr, attribute=value)

f                      required         a Python callable or string in
                                        the form "f(t), g(t)", just like Curve
low, high              required         left and right endpoints
ticks                  default=-10      request ticks according to the standard
                                        tick specification (see help(Ticks))
miniticks              default=True     request miniticks according to the
                                        standard minitick specification
labels                 True             request tick labels according to the
                                        standard tick label specification
logbase                default=None     if a number, the x axis is logarithmic
                                        with ticks at the given base (10 being
                                        the most common)
arrow_start            default=None     if a new string identifier, draw an
                                        arrow at the low-end of the axis,
                                        referenced by that identifier; if an
                                        SVG marker object, use that marker
arrow_end              default=None     if a new string identifier, draw an
                                        arrow at the high-end of the axis,
                                        referenced by that identifier; if an
                                        SVG marker object, use that marker
text_attr              default={}       SVG attributes for the text labels
attribute=value pairs  keyword list     SVG attributes
