Salesforce.com Winter 10 Release Admin Exam

Just took the Winter 10 Release exam and passed! As always, it left me with some questions of my own, and one specially sticks out. Wondering how others answered it.

It is related to one of my favorite features - new Charts. For those who have not yet tried these, they are really powerful.

• You can now drill down to the Filtered Source Report. Example, clicking on a wedge in a pie chart would automatically filter the underlying report to match the wedge.
  
• Colors can be assigned to picklist values like Stage on Opportunities/Donations.
  
• You can combine different data types (Combination Charts).
• You can enable Hover details for charts. On a Line, Vertical Column and Horizontal Bar chart, hover displays label and value. On a Pie, Donut, and Funnel chart label, value and % is displayed.

Anyway, coming back to the question on the exam -

On a Vertical Bar chart Filtered to Source report what can you click on, there are 3 right answers?

1. X - Axis (?, on the text I checked it)
   
2. Y - Axis (?, on the text I checked it)
3. Legend (No?)
   
4. Grouped Data (Yes)
   
5. Component Header (definite NO, you can't click on a Header)
   

I could eliminate #5 right away as you can click on a Title but not the Header. I am certain that you can click on the Grouped Data so that's in. Legend isn't available on a Vertical Chart unless you make it a Combination Chart, and even then it is not click-able. That leaves us with X -Axis and Y -Axis, which I selected along with Grouped Data as my answers; but am still not convinced as you really cannot click on the Axis'.

I would be curious to hear what you guys think.
