Showing Available VCS Objects

Question

How do you show what already defined VCS objects are available?

Answer

The show command will do this. As it is a method attached to a VCS canvas object, you have to first initialize a canvas:

>>> import vcs
>>> v = vcs.init()

The following lists all text-orientation objects currently defined:

>>> v.show('textorientation')

show can be used to list available graphics methods (e.g. isofill, scatter, continents, etc.), text objects (e.g. text-table, text-orientation), and templates. The argument for show is the method or object type "name" as a string, for instance:

ArgumentShow Displays
'colormap'Color maps
'fillarea'Fill area objects
'isofill'Isofill graphics methods
'line'Line objects
'xvsy' x(t) vs. y(t) plot graphics methods
'textorientation' Text-orientation objects
'texttable'Text-table objects
'template'Templates
