VisualAttributes

class glue.core.visual.VisualAttributes(parent=None, washout=False, color=None, alpha=None, preferred_cmap=None)

Bases: echo.core.HasCallbackProperties

This class is used to define visual attributes for any kind of objects

The essential attributes of a VisualAttributes instance are:

Parameters

• color – A matplotlib color string

• alpha – Opacity (0-1)

• linewidth – The linewidth (float or int)

• linestyle – The linestyle ('solid' | 'dashed' | 'dash-dot' | 'dotted' | 'none')

• marker – The matplotlib marker shape ('o' | 's' | '^' | etc)

• markersize – The size of the marker (int)

Attributes Summary

alpha	Transparency, given as a floating point value between 0 and 1.
color	Color specified using Matplotlib notation
linestyle	The line style, which can be one of 'solid', 'dashed', 'dash-dot', 'dotted', or 'none'.
linewidth	The line width, in points.
marker	The marker symbol.
markersize
preferred_cmap	A preferred colormap specified using Matplotlib notation
rgba

Methods Summary

copy([new_parent])	Create a new instance with the same visual properties
set(other)	Update this instance's properties based on another VisualAttributes instance.

alpha

Transparency, given as a floating point value between 0 and 1.

color

Color specified using Matplotlib notation

Specifically, it can be:

• A string with a common color (e.g. ‘black’, ‘red’, ‘orange’)

• A string containing a float in the rng [0:1] for a shade of gray (‘0.0’ = black,’1.0’ = white)

• A tuple of three floats in the rng [0:1] for (R, G, B)

• An HTML hexadecimal string (e.g. ‘#eeefff’)

linestyle

The line style, which can be one of ‘solid’, ‘dashed’, ‘dash-dot’, ‘dotted’, or ‘none’.

linewidth

The line width, in points.

marker

The marker symbol.

markersize

preferred_cmap

A preferred colormap specified using Matplotlib notation

rgba

Methods Documentation

copy(new_parent=None)

Create a new instance with the same visual properties

set(other)

Update this instance’s properties based on another VisualAttributes instance.
