TIBCO Data Visualization and Chart Types 2 — Questions and Answers
Question 1: In Spotfire, what is a 'Parallel Coordinate Plot' primarily used for?
- Showing time series trends
- Visualizing multi-dimensional data across multiple axes (Correct answer)
- Displaying geographic data
- Comparing two categorical variables
Correct answer: Visualizing multi-dimensional data across multiple axes
A parallel coordinate plot renders each variable as a vertical axis and draws a polyline per data row to reveal multivariate patterns.
Question 2: When would you use a 'Waterfall chart' in Spotfire?
- To show geographical distribution
- To illustrate cumulative effect of sequential positive/negative values (Correct answer)
- To compare category frequencies
- To display time-series forecasting
Correct answer: To illustrate cumulative effect of sequential positive/negative values
Waterfall charts show how an initial value is affected by a series of intermediate positive or negative values.
Question 3: What does 'Color By' configuration in a Spotfire visualization control?
- The background color of the entire page
- The color scheme used to encode a data column's values visually (Correct answer)
- The axis label colors
- The grid line colors
Correct answer: The color scheme used to encode a data column's values visually
'Color By' maps a data column to color, letting you visually distinguish categories or encode continuous values.
Question 4: Which Spotfire chart type is most effective for displaying the composition of a whole across categories?
- Scatter plot
- Stacked bar chart (Correct answer)
- Box plot
- Histogram
Correct answer: Stacked bar chart
A stacked bar chart shows part-to-whole relationships by stacking category segments within each bar.
Question 5: In Spotfire, what is the 'Marking' feature used for in visualizations?
- Adding text annotations to charts
- Interactively selecting and highlighting data points across multiple visualizations (Correct answer)
- Changing the color scale
- Sorting axis values
Correct answer: Interactively selecting and highlighting data points across multiple visualizations
Marking lets users select data points in one visualization and see those same rows highlighted across all linked visualizations.
Question 6: What is the purpose of the 'Size By' encoding in a Spotfire scatter plot?
- Controls the font size of labels
- Maps a numeric column to the size of each data point marker (Correct answer)
- Sets the chart canvas dimensions
- Adjusts the axis scale
Correct answer: Maps a numeric column to the size of each data point marker
'Size By' encodes a numeric measure as the physical size of each marker, creating a bubble-like effect.
