The Spectrum Icon Bar

The Spectrum Icon Bar
Prev	Using Spectral Windows	Next

An Icon Bar is present across the top of the standard toplevel windows containing spectra. The Icons provide easy access to commands to adjust the spectrum view and levels, as well as to print spectra and stop contour drawing that is in progress in a given window.

Adjusting the view or scale via the Icon bar will change the view for every spectral window that is contained within the same toplevel window as the Icon Bar. Control of the display parameters of individual windows can be done with the similar Icon Bar that is found in the Spectrum Attributes dialog (see below).

Spectrum Attributes: Open the Spectrum Attributes Dialog
Add Favorite: Save view of current spectrum. Will prompt for a name to save the info to. File will be stored in the "win" sub-directory of the current project. Reload the view with from the Window->Favorites menu item.
Print: Open a dialog for printing the spectrum. Printing in NMRViewJ happens through the operating systems normal print dialog. Use the print dialog to set such things as the output device (including whether to send the output to a file rather than a printer).
Draw: Draw the spectrum using all currently selected parameters. Use this to refresh the spectrum after changing a parameter which did not result in the spectrum being automatically redrawn.
Undo: Undo the last action. Not all actions are undoable
Redo: Redo the last undone action. Not all actions are undoable
Full: Set the display region of the spectrum to their full extents and draw the spectrum. For 1D spectra this effects only the chemical shift axis, and not the vertical scale. For 3D and higher spectra only the dimensions on the x and y axis of the display are set to the full values.
Expand: Expand the display region so that the display region corresponds to the area currently enclosed in the box formed by the crosshairs. This effects only the chemical shift axes displayed on the x and y axes of the plot. Press and hold the mouse button to auto-repeat this action.
Zoom In: Zoom the display into a region around the center of the currently displayed region. A smaller portion of the spectrum will be displayed, and the displayed peaks will look larger. The positions of the crosshair lines have no effect on this operation. Press and hold the mouse button to auto-repeat this action.
Zoom Out: Zoom the display out from the center of the currently displayed region. A larger portion of the spectrum will be displayed, and the displayed peaks will look smaller. The positions of the crosshair lines have no effect on this operation. Press and hold the mouse button to auto-repeat this action.
Pan left: Shift the display region left on the spectrum. The display region will cover the same chemical shift range, but will be at higer chemical shift values. Press and hold the mouse button to auto-repeat this action.
Pan Right: Shift the display region right on the spectrum. The display region will cover the same chemical shift range, but will be at lower chemical shift values. Press and hold the mouse button to auto-repeat this action.
Pan up: Shift the display region up on the spectrum. The display region will cover the same chemical shift range, but will be at lower chemical shift values. This only has an effect on spectra that have two or more dimensions. Press and hold the mouse button to auto-repeat this action.
Pan down: Shift the display region down on the spectrum. The display region will cover the same chemical shift range, but will be at higher chemical shift values. This only has an effect on spectra that have two or more dimensions. Press and hold the mouse button to auto-repeat this action.
Automatic Level: Automatically calculate and set the display level to a "reasonable" value. For spectra with two or more dimensions, the command approximates the noise level in the spectrum, and sets the contour threshold to a value five times higher. For 1D spectra the command sets the plot scale so that the largest peak in the display region is completely displayed.
Level up: Raise the contour threshold of spectra with two or more dimensions. Generally, fewer peaks will be displayed, and their displayed footprint will be smaller. For 1D spectra the tops of peaks will be lower in the display region. Press and hold the mouse button to auto-repeat this action.
Level down: Lower the contour threshold of spectra with two or more dimensions. Generally, more peaks will be displayed, and their displayed footprint will be larger. For 1D spectra the tops of peaks will be higher in the display region. Press and hold the mouse button to auto-repeat this action.
Stop: Stop drawing the current spectrum. As each spectrum is drawing itself it periodically checks for a "stop" flag. Clicking this button sets the "stop" flag. There may be a short delay between clicking the button and the time at which the spectrum display stops. Press and hold the mouse button to auto-repeat this action.
