Anyone could help me to create my mashup!

Hi,

yes indeed, this has been hidden well. The key is that filtering works slightly different if label or images trigger the filter action.

In contrast to charts, tables and maps an image or text label doesn't return a selection coordinate. If you click one of a pie chat's segments the it's name is returned. But as images don't represent multiple values nothing is returned. However, an image might set selections in other widgets so selecting a table row might be simulated. (Such a helper table might be hidden.)

So, before clicking images filters your gauge you need a widget in between, e.g. as depicted below.

The table and the speedo are driven by the same data feed which consists of the two columns turnover and region. Clicking one of the images sets the table's selection, i.e. selects North, South, ... An image or label have the specify link action next to their data asignment control.

This shows a dialog which is similar to data assignment. Basically you can define two things: Compose an URL which is opened whenever a user clicked the image - or - set another widget's selection to a constant text value.

Activating define selection enables you to select the table from the widget list. By specifiing the constant text value North clicking the image is equivalent to select a table row where region column equals North.

Based on this the speedometer might be filtered according to the table. If you hide the table (behind images or by decreasing it's size) image clicking simulates speedo filtering.
