Control how often the selected graph-format Sensor History Report or Custom Sensor History Report will refresh automatically, if at all.
You can use any auto-refresh setting when you create a graph with less than 50,000 data points. When you create a graph with 50,000 - 199,999 data points, the graph will refresh only when you select a refresh interval of five minutes or greater. When you create a graph with 200,000 data points or more, the graph will not refresh.
These settings are client-specific, and have no affect on the refresh settings used by other Data Center Expert clients.
