Show-All List-Based Design
This design is fundamentally different from the previous two designs - it assumes a fixed layout which always shows all the available channels in a list. In other words we can also say that this design is layout-free. It also presents visualizations differently - in the so-called graph screen which gives a visualization the full screen.
Main Screen
The main screen shows a list of available channels and color codes them based on recent activity. Tapping a channel selects its detailed view (bottom right) which displays live graphs of any numeric quantities. Tapping a graph or number in a channel brings up the graph interface (below).
Graph screen
Graph interface fills the screen. Interaction is similar to a photograph which users are familiar with. Pinch or double-tap to zoom, drag to pan. A single tap anywhere freezes/unfreezes the graph (ie stops or starts live data being added.)
More traces can be added to the plot by pressing Menu and then selecting Add Trace. The Add Trace window appears (lower right) which allows the user to browse through available channels and variables in those channels. More than one new variable can be selected.

When graphing text, we display small colored bars at the bottom of the screen that change color when the text changes. While this does not convey what the text is, it conveys that it has changed, which may still be useful. We use a hashing strategy to display colors, so that the same text will always have the same color.
