10 new Google Visualization widgets for RAP [message #131772] Thu, 07 May 2009 21:31 Go to next message

Google Visualization API consists of a number of charts, maps, and graphs
for the visualization of data. See
http://code.google.com/apis/visualization/documentation/gall ery.html

The 10 new widgets for Eclipse RAP include:
(1) MotionChart, which I believe is Google's implementation of the
Trendalyzer, as seen on gapminder.org and at TED -
http://www.ted.com/index.php/talks/hans_rosling_shows_the_be st_stats_you_ve_ever_seen.html
(2) line chart
(3) scatter chart
(4) partial implementation of GeoMap (regions supported, markers not
supported)
(5) pie chart
(6) column chart
(7) bar chart
(8) area chart
(9) gauge
(10) timeline

All widgets permit any supported settings to be passed into the widget.
Each widget expects a characteristic format of data. See the Google
Visualization API documentation for each widget.

All except gauge and motion chart send selection events to RAP.

Example code:
JSONGoogleDataTable dataTable = new JSONGoogleDataTable();
dataTable.addColumn("theyear", "Date", "string", null);
dataTable.addColumn("CO2", "CO2", "number", null);
dataTable.addColumn("Temperature", "Temperature", "number", null);
dataTable.addRow(new Object[] {"1970", 325, 14.1});
dataTable.addRow(new Object[] {"2009", 389, 14.7});
widgetData = dataTable.toString();

ColumnChart chart = new ColumnChart( composite, SWT.NONE );
chart.setWidgetOptions("{width: 300, height: 300}");
chart.setWidgetData(serializedData);
gridData = new GridData(300, 300);
chart.setLayoutData(gridData);

...

public void handleEvent(Event event) {
log.info("Event: " + event);
VisualizationWidget widget = (VisualizationWidget)event.widget;
log.info( "Selected item=" + widget.getSelectedItem() +
"; row=" + widget.getSelectedRow() +
"; column=" + widget.getSelectedColumn() +
"; value=" + widget.getSelectedValue());
}

Most are Flash components. No Google API key is required for the current
implementation.

I am currently hosting the code here in the repository for my project
INQLE, however I can put it elsewhere e.g. create a new project if folks
desire.
http://code.google.com/p/inqle/source/browse/#svn/trunk/org. inqle.ui.google.widgets

Many thanks to Ivan Furnadjiev, for his energetic help in the development
of these widgets! Thanks also to Christian Schmidt of Qooxdoo. Without
their help I could have not gotten this working.

AWESOME!

I think this stuff would be perfect for the RAP incubator!
http://www.eclipse.org/proposals/rap-incubator/

The project is still in the proposal phase but should have a creation
review.

What about you joining the project as a committer with the initial
contribution you have for the 10 viz widgets?

What does the RAP team think ;)?

This is cool!
David, please let us know if you wish to become a committer on the
incubator and host your code there.

that's a great contribution! Thanks for sharing this code.

We added your contribution as an initial work area to the RAP incubator
