Functions of the Spectra ribbon => Click onto a button for descriptions

new Spectra View Here you can create a new spectra view, which is the general tab type for displaying and processing all kind of spectra. Change the tab name after double-clicking on it. Change the tab order by drag&dropping tabs. Tabs can be dragged out of the main window as separate windows and docked into it again afterwards, but not all functionality is available for such separated tabs. Each view type has its own characteristic set of inline buttons at the top (explained with their respective ribbons). Spectra View function buttons These inline buttons are part of all Spectra tabs, even of those special tabs used for another purpose, like in Automate, Acquire and Identify areas. Here are the explanations: - : explains all available zooming and other plot interaction functions with mouse buttons - : For zooming in with the left mosue button, here you can switch between vertical, horizontal or bi-directional zooming. With "Zoom history" activated, the zooming out (with right mouse button) goes the same steps backwards, that were used on zooming in. - : Functions for selecting axis types and spectrum line type, as explained in Plot/Views. - : Functions for legend handling, as explained in Plot/Views. - : Get spectral data in with "Paste form Clipboard", get a plot image out with "Copy Plot to Clipboard" and get spectral data out with "Copy data to clipboard", as explained in File. - : Copy a single spectrum to another tab by grabbing the spectrum trace with the left mouse pointer and dragging it to another tab header. - : Duplicate the current tab with all spectra content into a new tab as a copy. Great for "branching" needs in processing, also consider Undo/Redo functions. - : Show spectrum properties for the currently selected, similar to the functions from Display & Data properties. Change the selected spectrum by clicking on the spectrum trace or its legend entry. - : Show a print preview and print the current plot from there. - : Undo and Redo the previous processing step. Define the size of Undo/Redo stack from File > Options.

Remove Spectra Last Spectrum: remove the last spectrum in the current's tab spectrum list. Short key: BACKSPACE. All Spectra: remove all spectra from the current tab. Short key: SHIFT+DELETE. Select...: Select one or several spectra for deletion in the left side list and move them to the right side list with the buttons in the middle. The OK button will execute the actual removal. Short key: DELETE.

Colorize by property Colorize a series of spectrum traces, based on the chosen parameter and the defined coloring style. Activate/ deactivate the function by clicking the main button, select the options from the dropdown menu. As parameter, you can select: - y value (at a defined position) - minimum value (in a defined range) - maximum value (in a defined range) - average of y values (in a defined range) - standard deviation of y values (in a defined range) - area under curve (in a defined range) - peak position (in a defined range) - center of gravity (in a defined range) - time stamp (for a series with time stamps assigned) - ... Choose from a number of coloring styles, and several ways of mapping the colors to values (with auto-ranging or else manual setting the boundaries). On the right side, there is a color preview for the spectrum trace selected in the top dropdown selector. With the Apply button, the current settings are applied to the current spectra series. The window only closes after clocking onto the Close button. This is perhaps one of the most underrated Spectragryph functions. Use it for great insight!

Spectra Properties For the spectrum selected in the top dropdown selector, you can quickly set: - the line colour ( from the dropdown color selector) - the line type: solid, dashed or dotted - the line width: ranging from "normal" and "+1" up to "+6". The line width is used as a relative width offset from the overal plot line width, which can be set with the "Lines thicker" and "Lines thinner" buttons from the Plot/Views ribbon For the same selected spectrum, show the spectrum information from the second dropdown selector. Click on the down-right options arrow to show the spectrum properties window, with access to "Display", "Data", "Information" and "LogText" sections for the current spectrum. Switch between spectra with the top dropdown selector. - the "Display" area allows to assign individual line color, width and type. Optionally, assign the same color to all spectra. - the "Data" area allows to assign individual spectrum names, and values for (excitation) wavelength, measurement temperature, concentration and path length; and also to calculate a sampel concentration from weighing in - the "Information" area shows the same content as the second dropdown selector from the ribbon - the "Log Text" areas is used for keeping meta data for some file formats, for keeping measurement parameters for acquired spectra and for bearing meta data and molecular structure information for library spectra

Sort spectra For changing the order of the currently loaded spectra. - "Sort A to Z" will sort alphabetically, based on legend texts - "Sort Z to A" will sort inverse alphabetically, based on legend texts - "Inverse List" will invert the current order, ignoring any other sorting criterium

With the Custom Sort window, you can put a series of spectra in your own customized order. Select a single spectrum or several spectra, then move them to their new place in the list with the right mouse button. The "Automatic sort" section on the right side has again the alphabetical and inverse-alphabetical sorting criteria, as well as temperature and wavelength, which are probably not used anyone outside a very narrow range of users:-)

Transfer spectra The little yellow fork truck helps to quickly transfer a selected or all spectrum to other specialized tabs, without the need of saving it first and the loading into the other tab. - if "automate view" is selected, all spectra get transferred into the most recent Automation tab for automated processing. If none is present, a new automation tab will be created. - if "identify view" is selected, the currently selected spectrum gets transferred into the most recent Indentification tab as sample spectrum for library seach. This only works, if an Identificaton tab with a loaded library exists.
