I'm having a problem with visualizations not getting the current values for data items in a datasource. I've got too many data items to just have the all of them update every scan. The documentation says the datasource should update the dataitems that are used on the screen, but not all of them are being updated that are used on the screen.

This is happening on a frame that takes an array and simulates scrolling by incrementing the index using the scroll bar. (See attached screenshot)

Is there a way to make sure the dataitems always get read when this visualization is in use?
