The export dialog is located under FILE => Export...
Basic configuration
Generally speaking, you always have to select one archive directory from which you want to export data. However, exporting data from more than one archive at the same time might be supported by some servers, too.
By selecting "Selected Graphs Only", you can make the program export data of selected PVs and formulas only.
You can enter a new time range for the query. Alternatively, you can load time ranges from the currently selected time axis.
The application contains an internal exporter that prints data in CSV format (actually, separated by tabs). Other exporters can be plugged in.
Per default, data is exported to an output window. However, you can bypass it by specifying a file. You can type a file path to the desired file manually, or you can select a file after pressing the "..."- button
As soon as you press OK, the export starts. Please take notice of the export progress. If it seems to take too much time or just to be too much data, you may interrupt the request (by pressing the red button next to progress bar). Note: data that was exported before interruption remains available
Advanced configuration
You can reach advanced settings by pressing the "..."- button and then selecting the "MORE..." menu item.
The method combobox contains data retrieval methods for export that are supported by current archive server.
You may enter a maximum number of data samples per PV.
For some export methods, it will make more sense to enter a period of time for which you want a single sample (this field and the "max number of values" field are symbiotic) You may enter your own timestamp format (useful, for instance, if you are going to send the file to Europe). Please, use the tooltip to see the supported syntax.
Finally, you can export data as well as status information, or just pure data.
