StoryTeller is the basis for dashboard design. Dashboards can contain any number of Slides, Charts, Images, Commentary, Videos, Tables, Animation, Media, close to anything that suits your project requirements. You can create a dashboard by choosing a StoryTeller Layout, then adding slides and populating those slides with content. Once done are you save your StoryTeller and click preview to see the finished result. What you see under Preview is what the end-client eventually gets access to.
Before you start adding charts, think about the StoryTeller layout. Do you want to have powerpoint slides or can it be a real dashboard?
