jSpecView

jSpecview is a Wave, Spectrum and 2-fold Matrices viewer Program.

Waves, Spectra and 2-fold Matrices are called Data-Items (DI) The program can handle multiple DI, each DI is contained in a Spectrum Box.

DI Waves or Spectra are Vector Items (VI) and can be placed in the same screen view. Matrices can not be added to VI.

Each DI Box can contain the following data:

• A disk file spectrum. Blue coloured label
• A Wave vector produced by scanning a detector signal and stored in a disk file. Blue colored label
• A 2-fold disk file Matrix .
• The resulting vector or matrix produced by a selected OPTool applied to a selected set of VI.

Every DI has its name displayed on a colored label.

Disk Waves and Spectra can reside anywhere in the file system with proper read permissions.

OPTool DI are calculated VI using as ingredients other DI.

See the Overlay and OP Help for more details.

OP DI have the name displayed in a Magenta color foreground.

Each Screen View handles Groups of Spectra and can have  3 different behaviors:

• Independent: Each spectrum has it own x-y scales and offsets.
• X-Homogeneous: All spectra have the same x axis scale and offset;
• Homogeneous: Every spectra has its own x and y scale and offset;

The groups can be displayed as arrays of selected number of Rows or Columns.

Other Display Options are available within the DISPLAY Menu.

The FILE Menu has the following sub-Menus:

Menu	MenuItem	Description
Add Spectrum to Display		Add a Disk spectrum to the current screen
Add Wave to Display		Add a Disk wave event to the current screen.
Add Matrix to Display		Add a Disk matrix to the current screen.
Create OP Tool		Build a new operation (OP) Data Item.
	WaveReader	Wave readout tool from file.
	ToolOps	Add a Data Item Operation on existing Data-Items.
	Wave Generator	Produces a wave shape
	DAQ Reader	Wave Reader from the on-Line source
Open DAQ Connection		Connection procedure with the on-Line source
Load Display Config		Read the display layout from a saved file.
Save Display Config		Save the display layout on a selected file;
Save Spectra		Save Data Items on a selected directory.
Exit		Quit jSpecview.

All available Wave-Readers (file and on-Line) can be started/stopped using the general Command SHIFT-S.

The readout can be stopped also every N Events per Run. During the readout operation the Panel update frequency is determined by a Panel Global parameter. Both the Update Event Number and the Event per Run Number can be defined to be the same for all Panels using the Menu Items in the DEFINE Menu.

Save Display Config is used to disk save a file with the description of the display layout. The display Config saves for each screen, the screen dimensions and name, the display options, the data items therein contained, the regions and disk Overlays.

Load Display Config reads the Display Configuration File a restores the Display layout.

Save Spectra saves only the content of spectra, not waves.

Save of the Overlay spectra is performed within the Panel PopUp Menu.

Once saved, OP spectra became a standard Disk file.
