Visualizing data isn’t

only about the final output…


…but also what you see along the journey


The New Question For OBIEE Owners

OBIEE“Answers”

OracleData

Visualization(Visual Analyzer)

Why do I need both?What do I use each for?Who is the target user?


Time for a cage match


RULES! (OK, really just notes)

• Intent: to show both execute multiple analysis scenarios•Caveat: this is a 30 minute session (check out the full session at Collaborate and Kscope)•Result: only one scenario will be shown today, and it admittedly favors Oracle Data Visualization

•Scoring: 7 point will be awarded to the first tool to answer the objective question•There are no timeouts and no challenges

Objective 1 Goal

•Why did Profits decrease last quarter?

For those keeping score

Demo Slides: Scenario 1


Multi-select ‘Month’ and ‘Profit Value’ then right-click and select “Create

Best Viz”


2. Change the visualization type using

this dropdown

1. Profits have dropped in recent months and we need to uncover why


Switch to a “Stacked Bar” visualization


Let’s see how this breaks down by quarter - drag

‘Quarter #’ to the “Color” drop zone


The color formatting allows us to easily see a 4th quarter drop this year

vs. a rise last year


Drag ‘Region’ to the “Trellis Columns” to see how this breaks out by

region


And drag ‘Brand’ to the “Trellis Rows” to see a

further breakout by region and brand


1. The largest drop-off has been in EMEA for the

BizTech brand.

2. Click the “X” to remove ‘Quarter #’ from the color

zone


Right-click on ‘BizTech’ to drill to a specific level in

the hierarchy


Let’s skip past LOB to see the Product Types

within BizTech


2. We can see that the largest drop-off was in the

Audio Product Type1. Notice how a filter was automatically applied for

‘BizTech’

3. Right-click on ‘Audio’ to drill across into another

dimension


On the “Data Elements” tab, search on ‘Channel’

and select the attribute to drill


3. Let’s change back to a line chart

1. Notice how a filter was automatically applied for

‘Audio’

2. The problem is definitely in the Store

channel


Is it a revenue or cost problem? Drag ‘Revenue’

to the “Values (Y-Axis)” zone


Drag ‘Variable Costs’ to the “Values (Y-Axis)” zone


We can see a large spike in costs in the 4th quarter

in our EMEA stores


Double-click ‘Month’ and ‘Profit Value’ to add them to the Analysis and click

the “Results” tab

Now let’s build the same scenario in

Answers to compare


1. Answers automatically creates a table view

based on the columns, but we don’t want that

2. Add a new view to the Compound Layout using the “Best Visualization”

feature


A graph is added…

…but the table view is still there, so delete it by

clicking the “X”


We can see the same dip in profits for the recent

quarter


To change to a bar chart and color the quarters,

we need to edit the graph view


We can use the dropdown to change to a

bar chart…


…and we can drag ‘Quarter #’ to the “Vary Color By” drop zone


Notice how Answers tries to make room for every

possible quarter value by narrowing the bars on the

chart

We can still draw the same conclusion as

before about the trend this year vs. last year


At this point, we can’t create a trellised view

within the standard graph view…


…so we have to click “Done” to exit back to the

compound layout


Add a simple trellis to the compound layout


We no longer want the graph view, so delete it by

clicking the “X”


The trellis view isn’t configured the way we

want, so we need to edit it by clicking the pencil


First we need to drag ‘Month’ to the “Group

By” zone in the Visualization


Now we need to drag the ‘Brand’ column into the

“Rows” zone…


And the ‘Region’ column into the “Columns” zone


The view is closer to what we want, but it’s a little small, so we click the

“Trellis Properties” button


We can change the “Graph Size” from

‘Medium’ to ‘Large…


…and click “OK”


Now that we’re getting there, let’s remove the

color formatting by color by dragging ‘Quarter #’ to

the “Excluded” zone


Like before, we can see that EMEA has a steep

decline in the 4th quarter in BizTech


Right-click to drill into ‘BizTech’…


…but since there is no ability to skip a level, it

drills to LOB first, which requires us to right-click

to drill again


Now we display Product Type, but we don’t need Brand nor LOB, so we

drag ‘Brand’ to the “Excluded” zone


Then we do the same thing for the

‘LOB’ column


We have our Product Type view, but now we can’t see all

of the types, so click the “Trellis Properties” button

again


Let’s change ‘Large’ back to ‘Medium’ to shrink the

graphs…


…and increase the total height of the entire trellis chart to 650 pixels, then

click “OK”


Now we can see the steep decline in Audio profits in EMEA for the

4th quarter


Now we want to drill across to our Channels, but we can’t do

that in Answers, so first we have to right-click on ‘Audio’ and drill to apply it as a filter


We can search the subject area for the

‘Channel’ column and then drag it to the “Rows”

zone


We don’t want Product Type nor Product

anymore, so we drag them both to the “Excluded” zone


Finally after excluding a lot of columns, we can

see that EMEA stores are declining the most


Let’s change the charts back to line charts by selecting

‘Line’ in the “View as” dropdown


Now we can drag both the ‘Revenue’ column…


…and the ‘Variable Costs’ column to the “Color By” zone to add them both to

the visualization


Now we can draw the same conclusion that revenue is flat but variable costs have increased, driving profits

down


If we wanted to share this, we could

click “Done”…


…and we now have a nice trellis chart on our

compound layout……but we have a

few extra views we don’t need…


…and a lot of extra columns in our criteria

that we should clean up for performance reasons
