graph-menu

The gnuplot graph window has the following options on a pop-up menu accessed by pressing the right mouse button(*) or selecting Options from the system menu or the toolbar:

Copy to Clipboard copies a bitmap and an enhanced metafile picture.

Save as EMF... allows the user to save the current graph window as enhanced metafile (EMF or EMF+).

Save as Bitmap... allows the user to save a copy of the graph as bitmap file.

Print... prints the graphics windows using a Windows printer driver and allows selection of the printer and scaling of the output. See also windows printing.

Bring to Top when checked raises the graph window to the top after every plot.

Color when checked enables color output. When unchecked it forces all grayscale output. This is e.g. useful to test appearance of monochrome printouts.

The GDI backend which uses the classic GDI API is deprecated and has been disabled in this version.

GDI+ backend draws to the screen using the GDI+ Windows API. It supports full antialiasing, oversampling, transparency and custom dash patterns. This was the default in versions 5.0 and 5.2.

Direct2D backend uses Direct2D & DirectWrite APIs to draw. It uses graphic card acceleration and is hence typically much faster. Since Direct2D can not create EMF data, saving and copying to clipboard of EMF data fall back to GDI+ while bitmap data is generated by D2d. This is the recommended and default backend since version 5.3.

Oversampling draws diagonal lines at fractional pixel positions to avoid "wobbling" effects. Vertical or horizontal lines are still snapped to integer pixel positions to avoid blurry lines.

Antialiasing enables smoothing of lines and edges. Note that this slows down drawing. Antialiasing of polygons is enabled by default but might slow down drawing with the GDI+ backend.

Fast rotation switches antialiasing temporarily off while rotating the graph with the mouse. This speeds up drawing considerably at the expense of an additional redraw after releasing the mouse button.

Background... sets the window background color.

Choose Font... selects the font used in the graphics window.

Update wgnuplot.ini saves the current window locations, window sizes, text window font, text window font size, graph window font, graph window font size, background color to the initialization file wgnuplot.ini.

(*) Note that this menu is only available by pressing the right mouse button with unset mouse.
