Designers can use their favorite design tools like Photoshop and Sketch to design the finest details of the user interface for their app. Single or multiple touch interactions can be applied on any UI element (layer) on each screen. Sophisticated animations can be created on-screen as well as screen transitions, using the powerful timeline animation features that Proto.io offers.

This prototype is a simulation of one part of the Pandora iPhone app. I have chosen to simulate the part of the app where the user selects a Pandora radio station and then proceeds to select that station. What I have demonstrated is how how the radio station animates from a small entry on a list to a large full screen entry and vice versa. If you would like to see how I created this prototype, please watch this video tutorial here: http://docs.proto.io/videos/pandora-tutorial-part-1/

Use a slider component to see the how a map of the US changes every month over a year based on the concentration of a fanbase. Uses a basic variable to change the container state of the map, with map assets created in Sketch. See how a version of it was created step-by-step within the Dashboard & Data Visualization webinar: http://docs.proto.io/videos/using-proto-io-for-dashboards-and-data-visualizations/ tags: variable | variables | data visualization | data viz | map | slider | states | months | USA

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.
