TIBCO Introduction To TIBCO Spotfire 3 — Questions and Answers
Question 1: In TIBCO Spotfire, what is an 'Information Link' primarily used for?
- Embedding hyperlinks in text areas
- Defining reusable, parameterized queries against data sources stored in the library (Correct answer)
- Linking two visualizations so they share the same axis scale
- Setting up email notifications when data changes
Correct answer: Defining reusable, parameterized queries against data sources stored in the library
Information Links are reusable query definitions stored in the Spotfire Library that retrieve data from configured data sources.
Question 2: Which Spotfire visualization is best suited for displaying the statistical distribution of a continuous variable, including median and quartiles?
- Bar chart
- Box plot (Correct answer)
- Pie chart
- Heat map
Correct answer: Box plot
A box plot displays the median, interquartile range, whiskers, and outliers, making it ideal for showing continuous variable distributions.
Question 3: What does 'limiting data' via a data table's row count limit accomplish in Spotfire?
- Permanently deletes rows from the source database
- Restricts the number of rows loaded into the in-memory data table to improve performance (Correct answer)
- Applies a filter that hides rows in visualizations without removing them from memory
- Converts all columns to string type for safety
Correct answer: Restricts the number of rows loaded into the in-memory data table to improve performance
Setting a row count limit controls how many rows are loaded into Spotfire's in-memory engine, which can significantly speed up analysis of large datasets.
Question 4: In Spotfire, what is the role of 'Marking' compared to 'Filtering'?
- Marking permanently removes unselected rows; filtering only hides them
- Marking is a temporary interactive selection that highlights data across visualizations; filtering removes data from all visualizations (Correct answer)
- Marking and filtering are identical operations
- Marking applies only to bar charts; filtering applies to all visualization types
Correct answer: Marking is a temporary interactive selection that highlights data across visualizations; filtering removes data from all visualizations
Marking highlights a subset of rows interactively and propagates across linked visualizations, while filtering actually removes non-matching rows from all visualizations.
Question 5: Which Spotfire feature enables a visualization to display different data depending on the value selected in another visualization on the same page?
- Calculated columns
- Action controls
- Cascading filters or marking-based filtering between visualizations (Correct answer)
- Data on demand
Correct answer: Cascading filters or marking-based filtering between visualizations
Spotfire's marking mechanism allows selections in one visualization to filter or highlight data in other linked visualizations on the same page.
Question 6: What is the purpose of the 'Details-on-Demand' panel in TIBCO Spotfire?
- To show raw data rows for the currently marked (selected) items (Correct answer)
- To display help documentation for each visualization type
- To show aggregated KPIs for the entire dataset
- To list all calculated columns and their formulas
Correct answer: To show raw data rows for the currently marked (selected) items
The Details-on-Demand panel shows the underlying row-level data for whichever marks are currently selected in any visualization.
Question 7: Which Spotfire calculated column expression would return the natural logarithm of a column named [Revenue]?
- LOG([Revenue])
- LN([Revenue]) (Correct answer)
- SQRT([Revenue])
- EXP([Revenue])
Correct answer: LN([Revenue])
The LN() function in Spotfire computes the natural logarithm (base e) of a value, while LOG() computes the base-10 logarithm.
