string

depending on choice-name

Used to set the logical function for drawing. The logical function used is set by x1. Usual values are: 3 for copying (default), 6 for animation and 0 for clearing. See alufunctions for more details.

Switch "on" or "off" the auto clear mode for graphics. When the auto clear mode is "on", successive plots are not superposed, ie an xbasc() operation (the graphics window is cleared and the associated recorded graphics is erased) is performed before each high level graphics function. Default value is "off".

Set the background color of the current Axes object. The color argument is the colormap index of the color to use.

Set the clipping zone (the zone of the graphics window where plots can be drawn) to the rectangle (x,y,w,h) (Upper-Left point Width Height). This function uses the current coordinates of the plot.

Set the default color for filling, line or text drawing functions. value is an integer projected in the interval [0,whiteid]. 0 is used for black filling and whiteid for white. The value of whiteid can be obtained with xget("white").

Set the colormap as a m x 3 matrix. m is the number of colors. Color number i is given as a 3-uple cmap(i,1), cmap(i,2), cmap(i,3) corresponding respectively to red, green and blue intensity between 0 and 1.

In black and white mode (xset("use color",0)), set the dash style to style i (0 for solid line). In color mode (xset("use color",1 )) this is used to set line, mark and text color. This keyword is obsolete, please use xset('color',i) or xset('line style',i) instead.

Reset the graphics context to default values.

size. Note that fontsize applies to all fonts not only fontid .

Set the fonts size.

Set the foreground color of the current Axes object. The color argument is the colormap index of the color to use.

Set the floating point format for number display in contour functions. string is a string giving the format in C format syntax (for example string="%.3f"). Use string="" to switch back to default format.

plot3d. colorid=0 zero suppress the drawing of backward facing faces of 3d objects. This is technically called 'culling' and speeds up the rendering of closed surfaces.

This function is used to set the line drawing mode. Absolute mode is set with type=1 and relative mode with type=0. (Warning: the mode type=0 has bugs)

Set the current line style (1: solid, >1 for dashed lines).

Set the current mark and the current mark size. Use xset() to see the marks. Note that marksize applies to all marks not only markid .

Set the marks size.

Set the current pattern for filling functions. value is an integer projected in the interval [0,whiteid]. 0 is used for black filling and whiteid for white. The value of whiteid can be obtained with xget("white"). "pattern" is equivalent to "color".

If flag=0 the graphics are directly displayed on the screen. If flag=1 the graphics are done on a pixmap and are sent to the graphics window with the command xset("wshow"). The pixmap is cleared with the command xset("wwpc"). Note that the usual command xbasc() also clears the pixmap.

Set the thickness of lines in pixel (0 and 1 have the same meaning: 1 pixel thick).

If flag=1 then xset("pattern",.) or xset("dashes",.) will be used so as to change the default color for drawing or for filling patterns. If flag=0 then we switch back to the gray and dashes mode.

Set the position of the panner.

Set the width and the height of the current graphics window. This option is not used by the postscript driver.

Sets the width and the height of the current physical graphic window (which can be different from the actual size in mode wresize 1). This option is not used by the postscript driver.

Set the current window to the window window-number and creates the window if it does not exist.

Set the position of the upper left point of the graphics window.

If flag=1 then the graphic is automatically resized to fill the graphics window.

xdel();xset("wresize",1);plot2d();xset("wdim",1000,500)

If flag=0 the scale of the graphic is left unchanged when the graphics window is resized. Top left panner or keyboard arrows may be used to scroll over the graphic.

xdel();plot2d();xset("wresize",0);xset("wdim",1000,500)
