Title: Active Report - Different Behaviour for Legacy Chart vs Visualisation
Post by: chewza on 17 Sep 2019 11:10:14 AM
Hi there

When I want to use a data button bar to filter the values in a Chart, I have to go through the hassle of the using a data deck, connecting the button bar to the deck, and doing a master-detail relationship to the chart in the deck.
From what I can gather, this is because there is not option to choose "Filter"in the connection to a (legacy) chart.

With C11 visualisations, it seems far more straigthforward - you can connect the data button bar directly to the chart, since the option to "Filter" is there  - you are not confined to "select". So is it just a case of always using visualisations rather than charts to make life easier?

Am I missing something? Is the "master-detail"method no longer required?

Many thx
Chris

Hi Chris,

The difference between charts and visualizations (for Active Reports, anyway) is that charts are rendered server-side and presented in the report as images, whereas visualizations are rendered on-the-fly client side. What this means for an active report (which by design can be interacted with offline from the Cognos server) is that all chart combinations have to be pre-rendered and stored on cards in a deck/data deck as the report output is being generated, whereas visualizations can be re-rendered within the saved report output, so can be filtered.

Hope that makes sense!

MF.
