The chart is frozen in its current state and will not change when further selections are made. A detached chart is marked with (Detached) after the title. The chart can be re-attached with the Attach command
QlikView allows users to detach a chart from the underlying data model. When a chart is detached, the object no longer responds to user selections. When the user re-attaches the object, it instantly updates to reflect the current state of the selections.
Alternate States are similar to this. The QlikView developer can create multiple states within a QlikView document and apply these states to specific objects within the document. The end-user can create copies of these objects (server objects) and then put those objects into different states.
The most important difference between Detach and Alternate States is that ALL objects in a given state will respond to user selections made in that state. Objects in a given state are not affected by user selections in the other states.
Alternate States are not accessible in the load script. They are a UI feature.
The developer invokes the Alternate States dialog from Alternate States... button on the Document Properties: General tab. The QlikView developer can create any number of states within the QlikView document and provides a name for each state created. Once Alternate States functionality is enabled, the QlikView developer can also create new states from within screen objects. End-users who access QlikView documents from a QlikView Server can make use of Alternate States but cannot create Alternate States.
Linked objects - it means that qlikview treats objects as one object with the same properties but in a different location. Trouble is (at least for me) is that I never really can unlink object. I see that objects are linked - (2 linked object) in caption, I click unlink object but they remain linked...
Alternate State is the ability to compare multiple selections from the same data to each other. Qlikview developer can create multiple states within a QlikView document and then apply these states to specific objects within the document. This feature can be utilized to compare multiple groups of,
for example, sales. It is also useful to compare selected products vs the rest of the products. you can compare the sales of different products to sales in other countries or different product groups for a particular year 2011 side by side in the same charts.
It allows to create a named states that operates independently to each other.
Detach : When a chart is detached it is frozen in its current state and will not change when further selections are made by users.By default all charts are attached and are effected by the selections in filters user makes.
Unlinking an object: Just use the context-menu of the object and go to Linked Objects => Unlink This object
Linked objects share the same object ID. If an object will be unlinked a new object ID will be assigned to the unlinked object.
When two or more objects are linked they share all properties with the exception of size, position and display state (normal, maximized, minimized). When you change the properties of one object the change is immediately reflected in the other linked objects. Linked objects may reside on the same sheet or on different sheets.
Once object is unlinked, properties are not shared anymore and changes in properties are not reflected on other objects.
