Auto Refresh Guidelines

Choosing a unit smaller than one second generates large amounts of returned data. The system calculates the expected return size and prevents you from requesting an amount larger than the maximum size specified in the Analysis Sample Size Limit in the System Configuration subsection in the Other Preferences section.
Auto-Refresh is Memory and CPU intensive. For best results, follow the Sizing Guidelines for minimum equipment specifications found in the Getting Started Guide.
If you delete the last tag in a chart that is running Auto-Refresh, then Auto-Refresh automatically is disabled (Off) for that chart.
