"""
|
||
|
|
Axislines includes modified implementation of the Axes class. The
|
||
|
|
biggest difference is that the artists responsible for drawing the axis spine,
|
||
|
|
ticks, ticklabels and axis labels are separated out from Matplotlib's Axis
|
||
|
|
class. Originally, this change was motivated to support curvilinear
|
||
|
|
grid. Here are a few reasons that I came up with a new axes class:
|
||
|
|
|
||
|
|
* "top" and "bottom" x-axis (or "left" and "right" y-axis) can have
|
||
|
|
different ticks (tick locations and labels). This is not possible
|
||
|
|
with the current Matplotlib, although some twin axes trick can help.
|
||
|
|
|
||
|
|
* Curvilinear grid.
|
||
|
|
|
||
|
|
* angled ticks.
|
||
|
|
|
||
|
|
In the new axes class, xaxis and yaxis is set to not visible by
|
||
|
|
default, and new set of artist (AxisArtist) are defined to draw axis
|
||
|
|
line, ticks, ticklabels and axis label. Axes.axis attribute serves as
|
||
|
|
a dictionary of these artists, i.e., ax.axis["left"] is a AxisArtist
|
||
|
|
instance responsible to draw left y-axis. The default Axes.axis contains
|
||
|
|
"bottom", "left", "top" and "right".
|
||
|
|
|
||
|
|
AxisArtist can be considered as a container artist and
|
||
|
|
has following children artists which will draw ticks, labels, etc.
|
||
|
|
|
||
|
|
* line
|
||
|
|
* major_ticks, major_ticklabels
|
||
|
|
* minor_ticks, minor_ticklabels
|
||
|
|
* offsetText
|
||
|
|
* label
|
||
|
|
|
||
|
|
Note that these are separate artists from `matplotlib.axis.Axis`, thus most
|
||
|
|
tick-related functions in Matplotlib won't work. For example, color and
|
||
|
|
markerwidth of the ``ax.axis["bottom"].major_ticks`` will follow those of
|
||
|
|
Axes.xaxis unless explicitly specified.
|
||
|
|
|
||
|
|
In addition to AxisArtist, the Axes will have *gridlines* attribute,
|
||
|
|
which obviously draws grid lines. The gridlines needs to be separated
|
||
|
|
from the axis as some gridlines can never pass any axis.
