class FigureCanvasBase |
| |
The canvas the figure renders into.
Public attribute
figure - A Figure instance
|
| |
Methods defined here:
- __init__(self, figure)
- draw(self)
- Render the figure
- print_figure(self, filename, dpi=300, facecolor='w', edgecolor='w')
- Render the figure to hardcopy. Set the figure patch face and
edge colors. This is useful because some of the GUIs have a
gray figure face color background and you'll probably want to
override this on hardcopy
- switch_backends(self, FigureCanvasClass)
- instantiate an instance of FigureCanvasClass
This is used for backend switching, eg, to instantiate a
FigureCanvasPS from a FigureCanvasGTK. Note, deep copying is
not done, so any changes to one of the instances (eg, setting
figure size or line props), will be reflected in the other
|
class FigureManagerBase |
| |
Helper class for matlab mode, wraps everything up into a neat bundle
Public attibutes
canvas - A FigureCanvas instance
num - The figure number
|
| |
Methods defined here:
- __init__(self, canvas, num)
- add_axes(self, rect, axisbg)
- Add an axes to the current figure
- add_subplot(self, *args, **kwargs)
- Add a subplot to the current figure
- destroy(self)
- get_current_axis(self)
- Return the current axes
- set_current_axes(self, a)
- Set the current axes to be a
|
class GraphicsContextBase |
| | |
Methods defined here:
- __init__(self)
- copy_properties(self, gc)
- Copy properties from gc to self
- get_antialiased(self)
- Return true if the object shuold try to do antialiased rendering
- get_capstyle(self)
- Return the capstyle as a string in ('butt', 'round', 'projecting')
- get_clip_rectangle(self)
- Return the clip rectangle as (left, bottom, width, height)
- get_dashes(self)
- Return the dash information as an offset dashlist tuple The
dash list is a even size list that gives the ink on, ink off
in pixels. See p107 of to postscript BLUEBOOK for more info
Default value is None
- get_joinstyle(self)
- Return the line join style as one of ('miter', 'round', 'bevel')
- get_linestyle(self, style)
- Return the linestyle: one of ('solid', 'dashed', 'dashdot',
'dotted').
- get_linewidth(self)
- Return the line width in points as a scalar
- get_rgb(self)
- returns a tuple of three floats from 0-1. color can be a
matlab format string, a html hex color string, or a rgb tuple
- set_antialiased(self, b)
- True if object should be drawn with antialiased rendering
- set_capstyle(self, cs)
- Set the capstyle as a string in ('butt', 'round', 'projecting')
- set_clip_rectangle(self, rectangle)
- Set the clip rectangle with sequence (left, bottom, width, height)
- set_dashes(self, dash_offset, dash_list)
- Set the dash style for the gc. dash offset is the offset
(usually 0). Dash list specifies the on-off sequence as
points
- set_foreground(self, fg, isRGB=None)
- Set the foreground color. fg can be a matlab format string, a
html hex color string, an rgb unit tuple, or a float between 0
and 1. In the latter case, grayscale is used.
The GraphicsContext converts colors to rgb internally. If you
know the color is rgb already, you can set isRGB to True to
avoid the performace hit of the conversion
- set_graylevel(self, frac)
- Set the foreground color to be a gray level with frac frac
- set_joinstyle(self, js)
- Set the join style to be one of ('miter', 'round', 'bevel')
- set_linestyle(self, style)
- Set the linestyle to be one of ('solid', 'dashed', 'dashdot',
'dotted').
- set_linewidth(self, w)
- Set the linewidth in points

class RendererBase |
| | |
Methods defined here:
- draw_arc(self, gcEdge, faceColor, x, y, width, height, angle1, angle2)
- Draw an arc centered at x,y with width and height and angles
from 0.0 to 360.0
If faceColor is not None, fill the rectangle with it. gcEdge
is a GraphicsContext instance
- draw_line(self, gc, x1, y1, x2, y2)
- Draw a single line from x1,y1 to x2,y2
- draw_lines(self, gc, x, y)
- x and y are equal length arrays, draw lines connecting each
point in x, y
- draw_point(self, gc, x, y)
- Draw a single point at x,y
- draw_polygon(self, gcEdge, faceColor, points)
- Draw a polygon. points is a len vertices tuple, each element
giving the x,y coords a vertex
If faceColor is not None, fill the rectangle with it. gcEdge
is a GraphicsContext instance
- draw_rectangle(self, gcEdge, faceColor, x, y, width, height)
- Draw a rectangle with lower left at x,y with width and height.
If faceColor is not None, fill the rectangle with it. gcEdge
is a GraphicsContext instance
- draw_text(self, text)
- Draw a text instance
- get_text_extent(self, text)
- Get the text extent in window coords
- new_gc(self)
- Return an instance of a GraphicsContextBase
