SPLK-1001 Practice Question: Creating Reports, Dashboards and Visualizations
A security analyst creates a dashboard to monitor failed login attempts over the past 24 hours. Which visualization type is most appropriate for showing the trend of failed logins over time?
⚠ Common exam trap
Splunk often tests the misconception that a pie chart can show changes over time because it visually represents parts of a whole, but the trap here is that pie charts are static and cannot display temporal trends, leading candidates to incorrectly choose it for time-series data.

Correct answer & explanation
✓
Line chart
A line chart is the most appropriate visualization for showing the trend of failed login attempts over time because it plots continuous data points along a time axis, allowing the analyst to easily identify patterns, spikes, or declines in the event count. In Splunk, a timechart command (e.g., `timechart count by action`) generates data that is best rendered as a line chart to display the temporal progression of failed logins over the past 24 hours.
