3. © 2012 IBM Corporation 3 Agenda  What is the visualization / charting feature?  Terminology  What is a View?  Prerequisites to create a chart  Anatomy of a chart  Chart types  Demo – creating a view, a bar chart, and the effect of changing chart settings  Creating a view  Creating a chart  Effect of application data type and plot event type on chart output  Summary

4. © 2012 IBM Corporation 4 Visualization / Charting  Allows users to see the attributes of an operator's output port stream graphically  Bar charts, line charts, and tables of stream attributes  Other users can be given permissions on charts  Charts can be “detached” from the console and appear standalone  Charts are rendered in svg in Firefox and Internet Explorer  Charts are dependent on a view for tuple data

5. © 2012 IBM Corporation 5 Terminology  Tuple – an individual piece of data in a stream  Attribute – the name of a field in a tuple  Data stream – a running sequence of tuples  Operator – manipulates the tuple data from the incoming stream and produces an output stream  Job – The SPL application is compiled into an Application Description Language (ADL) file that is used to run the job  Viewable stream - a data stream produced by an output port in a running job that produces tuples  View – an in-memory buffer in SWS that contains tuple data from the output port. Only those attributes defined for the view are contained in the buffer.  Chart – a visual representation of the selected attributes in the tuples for the view associated with the chart.

6. © 2012 IBM Corporation 6 What is a View? JobSWSBrowser Line chart Bar chart Table View  In a running job tuples are sent from the output port of one operator to the input port of the next operator  If a view is defined on an output port, tuples are also sent to the view  The view buffers the tuples in memory in SWS  Each chart that uses a view retrieves data from the view's buffer  To create a chart...

7. © 2012 IBM Corporation 7 Prerequisites to create a Chart  An instance with a running job  The data stream produced by the job must be viewable –A “viewable stream”  The job must contain at least one operator that produces tuples  A view must be created prior to chart creation –Views are created using the SWS console  Most importantly: –Understand the attributes and their data type in the application. –Determine the number of events to plot: “summary” or “scrolling window”

10. © 2012 IBM Corporation 10 Demo – creating a view and a bar chart on the view  Create a view, and add attributes to the view  Create a bar chart over the view  Show how changing the settings impacts the chart

11. © 2012 IBM Corporation 11 Example – Create a view  Start the job and navigate to the Views item  Click the Add.. button in the Views pane  Name the View  Select the job  Select the stream –Operator and Port  Select the attributes to include in the view  Specify a filter on the tuple data –Optional

12. © 2012 IBM Corporation 12 Creating a View  Select the job  Select the stream –Operator and Port

13. © 2012 IBM Corporation 13 Creating a View  Select the attributes to include in the view  Specify a filter on the tuple data –Optional  Click “Finish”

14. © 2012 IBM Corporation 14 Example – Create a simple summary bar chart  Start the job and create the view  Click Add Chart button in the Charts Nav item –Name the chart –Select the view  Y- Axis Settings –Select the attributes to plot - SouthAmerica –Modify label value (optional) – left as the attribute name –Manually set the data range (optional) –Add or remove tick marks (optional) –Set chart refresh off or on and interval rate  X- Axis Settings –Events to plot – scrolling events or latest event –Labels – none or source and orientation  Appearance –Chart theme, grid lines –Orientation, grouping (clustered or stacked) and gap between bars –Display legend

15. © 2012 IBM Corporation 15 Chart Wizard – Title, Type and View

16. © 2012 IBM Corporation 16 Y Axis: Title, Attributes, Data range, tick marks, refresh 0 - 200,000

17. © 2012 IBM Corporation 17 X Axis: Title, Event type, Label source and orientation

18. © 2012 IBM Corporation 18 Appearance: Theme, grid lines and properties

19. © 2012 IBM Corporation 19 Summary Line Chart  The Chart Type is “Line”  The Chart Title is on the bottom  Y- Axis Settings –Selected 3 list attributes to plot –The label attribute is the attribute's values

20. © 2012 IBM Corporation 20 Effect of Application Data Type and Event Type on Charts  Event type is “latest event” - only the most recent event is shown  Data type of the single attribute to plot on the Y-Axis is “list” –The attribute, “negative”, has 12 values in one list item  Data type of the attribute used for the X-axis labels is list  One to one relationship between # of items plotted and # of labels –The attribute, “brands”, also has 12 values in one list item

21. © 2012 IBM Corporation 21 Effect of Application Data Type and Event Type on Charts  Event type is “scrolling” - 10 events appear in a “window”  Each event shows one “negative” list item with 12 values – Each event's label is the “brands” list item, with 12 brand names  The legend shows a marker for each “negative” entity in one list item  The Y-axis attribute and the X-axis label attribute are the same as in the previous chart.  This is confusing... how could we make the chart more understandable?

22. © 2012 IBM Corporation 22 Effect of Application Data Type and Event Type on Charts  Y-Axis label is now the attribute “brands”  X-Axis label is now event time

23. © 2012 IBM Corporation 23 Summary  Suggestions when creating charts –Experiment with the chart settings to become familiar with their affect –Know your application data types, it's possible the application may need to be modified to produce the chart you want –Determine if you want a summary (latest event) or scrolling chart –Create a table chart in addition to a bar or line chart to more easily examine data Thank you!
