Alpana is dedicated to data exploration and interactive display of information.
Using a filter at runtime allows the user to focus the visualizations on a sub-set of the data.
Dashboard Parameters are the mechanism behind this dynamic filtering.

Dynamic filtering : Master Widget / Listener Widget

A Master Widget can be used at runtime to make selections that apply a filter to other Widgets.
Widgets that are configured to listen to this filter are called Listener Widget.

Internals

When the user clicks on a shape in a Master Widget, a DataSelect event is generated and sends the selected value into a Dashboard Parameter.
Listener Widgets receive the Dashboard Parameter value and add it as a filter to their data.
