Web Google Chart for OpenERP

This is an OpenERP addons to replace all chart of the web client by google chart version. It also adds several new features. Please consult the list of features further down.

Acknowledgments

Many thanks to CARIF-OREF La Réunion which has funded the near entirety of the development of this code.

Requirements

This addons is made for OpenERP version 6.1

Please bear in mind that Google Charts library need to be downloaded from google's site. So if you have an intranet OpenERP without access to Internet, this module is not for you.

Installation

Install this as any OpenERP addons, and then look at your charts.

Features

Besides all charts of OpenERP being replaced by google version:

several bugs were fixed from original chart.js from version 6.1.1
support of new type 'gauge' and 'pyramid' type of charts.

For a population pyramid, for example:
<graph type="pyramid">
  <field name="age" />
  <field name="gender_id" group="True" />
  <field name="nbr" operator="+"/>
</graph>
new aggregation operator # (namely equivalent to COUNT in SQL), and avg which is self explanatory.
all graphs can be customized much more than OpenERP, for example:
<graph string="Gauge Example" type="gauge">
  <field name="name"/>
  <field name="nbr" operator="+"/>
  <html>
    <graph-options>
      {
        width: 400, height: 120,
        redFrom: 90, redTo: 100,
        yellowFrom:75, yellowTo: 90,
        minorTicks: 5
      }
    </graph-options>
  </html>
</graph>
Options are the google chart ones. So documentation is available on google chart site.

Troubleshooting

It has occurred on some rare occasion that legacy chart.js seems to be loaded after the javascript code of this module, leading to google chart NOT replacing legacy charts. This remains to be confirmed as I cannot reproduce it.

To check if this is the case in your installation, you can comment the line in addons/web_graph/static/src/js/chart.js:
```
openerp.web.views.add('graph', 'openerp.web_graph.GraphView');
```
which you'll find in the 20 first line of this file. Then ensure your browser cache is emptied (Ctrl-Shift Del and select only cache, or use Ctrl-F5) to ensure you reload the new javascript. This could help you using web_google_chart if ever it didn't work on your installation.

Send me the result through the Issues tab if can reproduce this bug or have any information on it.
