3. Agenda Data visualisation and Silverlight/WPF Visualising objects Visualising data sets Toolkits and controls

4. The Business Problem Data != Information

5. The Business Problem It’s easy to miss important information in a sea of purely textual data Trends and correlations Special or different cases Trouble spots It’s often quicker to take in information with a graphical assist Quick way to get a “big picture” overview

6. The Business Problem

8. The Technical Problem GUI programming stalled in 1991 Low level graphics primitives Procedural drawing code Presenting data in a new UI required a whole new control

9. The Technical Problem Technical consequences Custom visualisations required extensive custom code Expensive to develop Third party controls Expensive to buy because expensive for vendor to develop Specific in purpose Cost of learning complex new control APIs Hard to justify the cost unless visualisation was a core requirement

10. The Technical Problem Business consequences Encouraged anaemic presentation of data Displaying data, not information “Battleship grey” and data grids Onus on users to detect patterns and anomalies

11. Silverlight and WPF Replace the appearance of a control without having to rewrite its entire behaviour Declarative, higher-level graphics API Flexible data binding mechanisms

12. Silverlight and WPF Writing simple visualisations is a matter of hours rather than days It is now affordable to be able to visualise your data your way Data visualisation is the killer application for Silverlight and WPF

13. Single Data Item Visualisation Binding IValueConverter IMultiValueConverter (WPF only) DataTemplate INotifyPropertyChanged

14. Visualising Single Data Items

15. Visualising a Collection of Data Toolkits and controls Custom visualisations

16. Visualisation Toolkits and Controls Silverlight Toolkit http://www.codeplex.com/Silverlight Charting controls (beta) WPF Toolkit http://wpf.codeplex.com Charting controls (beta) Third party controls (commercial and free) Charting, diagramming

17. Silverlight Charting Controls

18. Building Custom Visualisations ItemsControl Selector ListBox MultiSelector ItemTemplate / ItemTemplateSelector ItemsPanel / ItemContainerStyle INotifyCollectionChanged Bindable LINQ

19. Visualising a Collection of Data

20. Summary Silverlight and WPF data binding is completely different to VB or Windows Forms Bind sizes, colours, positions, transforms, visibilities IValueConverter DataTemplate ContentTemplateSelector / ItemTemplateSelector Use panels to perform layout ItemsControl > ItemsPanel / ItemContainerStyle

21. Call to Action A meaningful visual display is a great way to put information in front of users Display information, not just data It is now affordable to be able to visualise your data your way Writing simple visualisations is a matter of hours rather than days But be realistic – embrace “good enough” Data visualisation is the killer application for Silverlight and WPF
