Sep 23 | Use the auto refresh setting to make sure you are always seeing the latest data in your charts.
When auto refresh is on, the workspace refreshes every 5 minutes and any workspaces and charts that do not have a specific end date set will be updated with any new data.

For historical charts specifically, if the end date is set to today and the Live button is on (green), new data will always be pulled in and the chart end date updated. If you want to keep specific dates set for a historical chart and not have the latest data pulled in, turn the Live button off and save the workspace.
