Visualization API
Project description
EEA App Visualization is the Core API for EEA Daviz. This package was added in order to be able to use EEA Google Charts without EEA Exhibit and viceversa or any other visualization library as a standalone visualization or as part of a bundle package (eea.daviz)
This package as standalone is just an API, you have to either install eea.daviz bundle, either install one of the available visualization libraries (eea.exhibit, eea.googlecharts, etc) in order to have a working Visualization Tool for your files.
Installation
If you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:
Update your buildout.cfg file:
Add eea.app.visualization to the list of eggs to install
Tell the plone.recipe.zope2instance recipe to install a ZCML slug
[instance] recipe = plone.recipe.zope2instance eggs = eea.app.visualization zcml = eea.app.visualization
Re-run buildout, e.g. with
$ ./bin/buildout
You can skip the ZCML slug if you are going to explicitly include the package from another package’s configure.zcml file.
