Plot Options

This module gives access to the scans within a project. The changes only affect the current display on screen. Files on the disk are not modified. To preserve the changes, scans must be exported manually.

Showing / hiding columns

Right-clicking on the header allows to show or hide offset and scaling columns.

Mouse interactions

Offsets and scaling

The values for scaling and horizontal / vertical offset can be changed by double-clicking on the current value. These values are only used for screen display, the scan's data is not changed. The changes are volatile. Closing a project or running a refinement will reset scaling and offsets.

All offset values can be reset by pressing CTRL + Space bar.

Scaling can be reset by right-clicking (unzooming) in the graph while the scan is activated.

Active Scans

Selecting a scan with the mouse sets its status to active, as indicated by the letter "A". Active scans are drawn with bold lines and the area under the scan is filled with a transparent color.

Multiple scans can be set active by holding the CTRL or SHIFT key while selecting the scans.

To unset all active scans, click on the empty area below the last scan in the list.

Some modules perform actions on the active scan:

Context Menu

Right-clicking on a scan opens a context menu allowing further interactions with the selected scan:

Export scan: Exports the selected scan to a new file. A file dialog opens to specify the file name. If multiple scans are selected, the tag <scan name> will be replaced with the scan's name. All export data formats supported by Profex can be selected. Raw scan data will be exported, scale factors and offsets will be ignored.

Remove selected scans: The selected scan will be removed from the project. This change is volatile, no files on the hard disk will be modified. Running the refinement or re-loading the file from disk will revert the change.

Copy current scan data: The selected scan's raw data is copied to the clipboard in ASCII format. The fields are separated by the separator specified in the preferences dialog ("Graphs -> Print and Export -> ASCII data export -> Field separator"). The default separator is the space character. Scale factors and offsets will be ignored.

Copy current HKL data: If the selected scan has HKL data, it will be copied to the clipboard in ASCII format. Scale factors and offsets will be ignored.

Export scan with offsets: Exports the selected scan to a new file. A file dialog opens to specify the file name. If multiple scans are selected, the tag <scan name> will be replaced with the scan's name. All export data formats supported by Profex can be selected. Refined offsets (EPS1, EPS2, EPS3), as well as the scale factor and offsets specified in the Plot Options list are applied to the exported data.

The name of the scan will be automatically appended to the selected file name. This avoids accidental overwriting of other scans exported from the same project.

Copy scan data with offsets: The selected scan's data with all offsets and scalings applied is copied to the clipboard in ASCII format. The fields are separated by the separator specified in the preferences dialog ("Graphs -> Print and Export -> ASCII data export -> Field separator"). The default separator is the space character.

Hide all phases: Unchecks and hides all scans flagged as "Phase".

Show all phases: Checks and shows all scans flagged as "Phase".

Add synthetic noise: Applies a synthetic Poisson noise pattern to the selected scan. This change is volatile, no files on the disk are modified. Export the modified scan to a new file to preserve the change.

Change scan color: Changes the color of the selected scan. This change is permanent and modifies the settings in the preferences dialog ("Graphs -> Scan Styles").

Change scan style:Changes the line and symbol style of the selected scan. This change is permanent and modifies the settings in the preferences dialog ("Graphs -> Scan Styles").

Show context help: Show this help text in the Context Help module ("Window -> Context Help").

Temporary Scans

Some modules create scans marked as temporary ("T"). One example is the Peak Fitting module. These scans are volatile (not written do disk) and will be discarded when the project is closed. Furthermore, they may be updated or deleted by the module that created them. Usually, the module allows to pin them to the project permanently. But they still need to be exported to disk manually to preserve them after closing the project.
