This session will first introduce IBM ILOG Elixir visual components and describe how they can help you improve data visualization for your Adobe Flex & AIR applications. In particular, the latest release and its new components such as pivot charts, calendars, heat maps, and Gantt project management displays will be described into details. Then the session will offer a deep technical dive, showing coding tips and tricks and how-tos information such as how to connect an ILOG Elixir Heatmap component to flickr API to display photos geolocation information, or how to extend the ILOG Elixir OrgChart to provide expand and collapse functionality. Finally we will see how Flex 4 and its new component architecture Spark could impact visual components development and use when released.

12. Tips & Tricks – From 2D to 3D Charts
 But we do not provide 3D API for customizing your display,
so you can't switch itemRenderer just play with styling
properties (fill, stroke…)
 Also items are not UIComponents, so you must use chart
specific events & effects like itemClick, showDataEffect …
not UIComponents events & effects (click, showEffect…)

13. Tips & Tricks – Building a Custom Gauge
 IBM ILOG Elixir provides with with predefined
Circular, Semi Circular, Horizontal and Vertical
Gauges
 They fit most simple use-cases but you might want
more, like mutli-value gauges
 Just assemble MXML elements and you’ll be able to
achieve what you need using the Gauges framework

15. Tips & Tricks – Expand/Collapse on the OrgChart
 By default the OrgChart is displaying the entire
OrgChart hierarchy available in dataProvider
 You might want to display only down to a certain level
and provide expand/collapse ability
 What you need:
1.The ability to filter the data depending on whether children are
expanded or collapsed
2.The ability for the user to interact with the OrgChart to target an
expand or a collapse action
 How do you achieve this?
1.By using a filterFunction on ICollectionView
2.By providing a custom OrgChartItemRenderer with a +/- button
 Let's take a look at the code & result!

17. Tips & Tricks – Create a custom Map dashboard
Workflow:
1. Create or get your map in ESRI SHP file format
2. Import it in IBM ILOG Elixir Custom Map Converter
3. Set Parameters
4. Export it as ActionScript
5. Include it in your Flex Builder Project
6. Use it in your MXML/AS code to represent dashboard
data
Let's do it live!

19. Tips & Tricks – Your Google Calendar in AIR
 IBM ILOG Elixir Calendar component is taking any Flex data as
input in a form of a list of quot;eventsquot; with optional recurrence
information
 That input must be provided as XML or ActionScript object in the
dataProvider, just a for any data-aware Flex component
 Two approaches:
1. Reading the iCal feed or exported file from Google Calendar:
 Allows to mashup from different iCal sources
2. Using the Google Calendar API
 More integrated with Google Calendar (authentication etc...)
05/14/2009 © ILOG, All rights reserved 19

20. Tips & Tricks – Your Google Calendar in AIR
Reading iCal feed or exported file
 Google Calendar export to iCal that is a simple
definition format for events
 Creating a dataProvider from iCal events is a matter of
reading TXT and creating AS objects
 For the recurrence information it could be a bit more
complex:
 One can provide any format of recurrence by providing his own
IRecurrenceDescriptor to the IBM ILOG Elixir Calendar
 However default IRecurrenceDescriptor implementation is
RFC2445 based so it is not needed to go as far

21. Tips & Tricks – Your Google Calendar in AIR
Reading iCal feed or exported file
 Google Calendar provides a Web Service API: http://
code.google.com/apis/calendar/docs/2.0/
developers_guide_protocol.html
 Create an ActionScript wrapper that calls this web
service and exposes result as ActionScript objects
 As in previous case, configure the IBM ILOG Elixir
Calendar with the right dataProvider

23. Tips & Tricks – Density Heatmap of Flickr photos
 The HeatMap principle:
 Displaying the densities or values of data objects using color at given
location (optionally over a map)
 In our case this is the density of photos taken at given geolocation and
available on Flickr over a map
 How do you achieve this?
 We create a MapHeatMap with a USStatesMap and a DensityHeatMap
and configure the heatmap to take location information in longitude &
latitude properties of the data objects
 We extend Flickr2AS API to manage Flickr quot;Placequot; API
 We request to Flickr photos over a particular quot;Placequot; using that API
(US in our case)
 We iterate over the results (paged results) and populate the data
provider of the DensityHeatMap with them as they correctly use
longitude & latitude properties
 We just look at the result

25. Tips & Tricks – Display scheduling information from MS Project
 IBM ILOG Elixir TaskChart control displays scheduling information
 MS Project is a widespread tool for building schedules
 How can your Flex/AIR application displays schedule coming from
MS Project?
 Follow these steps:
1. Export from MS Project using their XML format
2. Add an IBM ILOG Elixir TaskChart to your application
3. Read the XML in your AIR/Flex Application
4. Using E4X get information from the XML and populate the TaskChart
with it:
 Activities information
 Constraints information (which activity must be completed before
which one)

27. What's next? - Building on top of Flex 4
 Adobe intends to release Flex 4 in fall 2009
 What could we do?
1. Use FXG for skinning components/renders
 You get that for free, check our blog for sample of styling an IBM
ILOG Elixir 2.0 Gauge with FXG
2. Rebuild our components using Spark component model:
 inheriting from FxComponent or FxDataContainer
 accepting FXG Group for skins and ItemRenderer (extends
Group) for item renderers
3. Integrate into Flash Catalyst?
 should not be extensible in its first incarnation, need to wait for
future version
05/14/2009 © ILOG, All rights reserved 27

28. What's next? - Leveraging Flash Player 10
 Gumbo will require Flash Player 10 => we can rely on
Flash Player 10 APIs for Okra
 What can we do?
1. Use Vector.<> in place of Array:
 Significant performance improvement on intensive Array-based
computations like renderers layout computations (OrgChart)
2. Use Vector3D in 3D Charts:
 Remove our own implementation => reduce SWF size, improve
performance
3. Leverage 3D transformations in 3D Charts:
 Remove several classes => reduce SWF size
 Significant work compare to previous improvements
4. Leverage bidi text in all components?
 Let's see how Adobe integrates bidi in Flex text component and
use this
 Will only be part of Flex 4.1 not 4.0
