The main window is the starting point for configuration and analysis.
As a first step you should go to the settings tab and configure EuHunter to your needs. A detailed howto for settings can be found here.
In the header you have four fields that show basic stats for the selected group. You select a group in the treeview on the right.
If an error is logged you will get a visible signal - mouseover contains the error message, left click hides it.
The first tab shows your previous recorded runs as a table view with the most important stats right there. You can sort the data by clicking the header of the column you want to be sorted. You can reorder the columns with drag and drop to get the information you look for as you like it.
On the main window you have a treeview on the right that presents your runs under their groups. The default naming is the starting date of the run but you can name them as you like (in details or in new run window).
The treeview aswell as the overview have context menu wich offers actions to delete, edit, continue or show the run analysis.
delete: Removes the run from the datafile.
edit: Opens the selected run in the detail tab where you can edit it.
continue: Opens the new run window for the selected run to continue a paused run.
run analysis: Shows the run analysis window that holds a bunch of graphs for that run.
The detail view presents all the details for a selected run. Most fields are editable, some are calculated so after you changed something click the update button on the left. To save the changes you can click Save now - Save is disabled as long as you did not click update.
I guess this part is clear - at least after you read the help of the new run window where the data is explained in more detail.
The analysis tab offers an overview over your runs and all the runs in the selected group.
The group graph shows the return for all runs in the selected group.
The Run graph shows cost vs return and also the result for every run in the selected group.
