sajou.plot.markers_mpl module

This module contains an extension to the MarkerStyle class of Matplotlib.

It implements an additional set of markers which are used for the representation of different attributes of a structural analysis model.

In addition to the standard markers, the following are implemented:

marker description
‘ap’ arc with arrow (anti clock-wise)
‘an’ arc with arrow (clock-wise)
‘psx’ horizontal pinned support
‘psy’ vertical pinned support
‘rsx’ horizontal rolling support
‘rsy’ vertical rolling support
‘es’ encastrated support
‘rex’ ‘rolling_encastrated_x’,
‘rey’ ‘rolling_encastrated_y’,
‘rc’ ‘rotation_constrained’,

Bases: matplotlib.markers.MarkerStyle

Defines custom marker styles for Sajou

markers

list of known markes

fillstyles
