The rise of interactive time\u2010series data explorers for hotly debated topics makes such framing easy to produce and spread. Post\u2010hoc interventions like fact\u2010checking often arrive too late and suffer from persistence of belief. Prior work suggests that guardrails, in the form of contextual comparison lines embedded directly into charts, can reduce these effects. We propose and evaluate a practical set of guardrail sampling strategies for implementing such contextual lines in real systems. In a preregistered mixed\u2010design study with two real\u2010world scenarios (COVID\u201019 and Stocks), participants viewed persuasive charts with different sets of guardrails and reported trust, estimated rank in the dataset, expressed their perceived completeness of context, as well as subjective preference for different tasks. Across scenarios, guardrails improved trust, accuracy of performance judgments, and perceived completeness of context compared to the control. Taken together, the study offers practical guardrail sampling methods, evidence of their contextual benefits, and insights into participants' preferences.<\/jats:p>","DOI":"10.1111\/cgf.70460","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T06:12:48Z","timestamp":1781763168000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Guardrail Selection in Line Charts to Contextualize Persuasive Visualizations"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-7940-501X","authenticated-orcid":false,"given":"K.
