XLISP-STAT Under the X11 Window System

Window based graphics are available in XLISP-STAT on a workstation running the X11 window system. Graphics under X11 are fairly similar to Macintosh graphics as documented in this tutorial. A few points to note:

• Plot menus are popped up using a menu button in the top right corner of a plot.
• In plot interaction you can use any of the mouse buttons. Normally clicking any button in a plot unselects all selected points. To extend a selection, or have a rotating plot continue rotating after the button is released, hold down the shift key as you press any mouse button.
• How plot windows are opened in response to a graphics command depends on the window manager you are using. Under uwm , the default window manager on many systems, a little corner will appear which you can use to choose the position of your plot window.
• Slider dialog items are the only items that assume a three button mouse. In the central part of the slider the right button increases and the left button decreases the slider value. The middle button drags the thumb indicator.
• Postscript images of plots can be saved by selecting the Save to File item on a plot menu. The postscript file can then be printed using a standard printing command.
