Use Thick Traces and Use Antialiasing for Traces improve graph appearance but may result in slow drawing performance on some platforms, uncheck these options for faster drawing. By default trace rendering is optimised for best quality, select Optimise Rendering for Speed for faster redraw on platforms with restricted graphics performance. The Corrected traces can be drawn dotted or in a brighter shade of the measurement colour. Use Dark Background changes the colour scheme from light to dark. Enable Mousewheel Zoom allows the graph to be zoomed in or out using a mousewheel or trackpad. Limit Mousewheel Zoom Rate prevents the graph from zooming in or out too rapidly. The trace colours can be set up from here, or reset to their defaults. The r,g,b values for the trace colour are shown when hovering over the colour buttons.

Interface

The text under the toolbar buttons can be hidden by unchecking Show Toolbar Text Labels. The text under the graph buttons can be hidden by unchecking Show Graph Button Text Labels. The grid on the measurement thumbnails can be turned off by unchecking Show Grid on Thumbnails. Animate Task Panes controls whether the task panes (Target Settings etc) slide open and closed. General Font Size is the base font size (in points) for REW. Graph Font Size is the font size used for the graph axes. Font size changes do not take effect until REW is next started.

Suppress Soundcard Errors stops REW showing an error meassge if it cannot access a soundcard on startup, this may be used if REW is being used to analyse measurements on a computer without the audio niterfaces needed for making measurements.

If Confirm Unsave dMeasurement Removal is checked REW will ask for confirmation if you try to remove a measurement that has not been saved since it was last modified. This setting can also be changed from the removal confirmation dialog.

Under OS X Use OS X-style File Dialogs changes the file selection dialog to a format more like the native OS X file chooser, but note that the OS X-style chooser does not have the preview panel which REW uses to show the contents of mdat, req, calibration data and image files.
