Hi There,Thank you for your query.As stated above by other community members. If you un-check background it will turn off the horizontal chart bars and if you un-check "Anomalies" then the vertical line would be gone.Anomalies are basically the unexpected events in a period of time. e.g. a sudden rise or fall in a metric.Thanks!

Hi there,Thanks for your query.Are you talking about the "Project Link" under the Share tab at the top or intra-linking of panels and visualizations?As per my knowledge, they do not expire.You can check the below doc for intra-linking and project links.https://marketing.adobe.com/resources/help/en_US/analytics/analysis-workspace/analysis-workspace-features.htmlThanks!
