The performance history settings are configured in the Options dialog of Awesome Miner, in the Performance history section.
Both the dashboard for real-time statistics and the long-term performance history are configured in this section.
The long-term Performance history dialog can be access from the toolbar in the main window of Awesome Miner, in Tools -> Performance history.
Only the selected miners will be used in the dialog.
The Performance history dialog provides features to export to CSV-file, generate chars and reset all history. All statistics are saved in 5 minute groups,
but can be visualized in groups of 1 hour or 1 day as well.
