8.24 Command options (MGL)

Command options allow the easy setup of the plot by changing of global settings only for this plot. Options are specified at the end of string. Each option is separated from the previous text by symbol ‘;’. Options work so that them remember the current settings, change settings as it being set in the option, execute command and return the original settings back. So, the options usage for data handling commands or for graphics setup commands is useless.

The most useful options are xrange, yrange, zrange. They sets the boundaries for data change. This boundaries are used for automatically filled variables. So, these options allow one to change the position of some plots. For example, in command plot y; xrange 0.1 0.9 the x coordinate will be equidistantly distributed in range 0.1 ... 0.9.

The full list of options are:

MGL option: alpha val

MGL option: alphadef val

Sets alpha value (transparency) of the plot. The value should be in range [0, 1]. See also alphadef.

MGL option: ambient val

Sets brightness of ambient light for the plot. The value should be in range [0, 1]. See also ambient.

MGL option: crange val1 val2

Sets boundaries of color change for the plot. See also crange.

MGL option: xrange val1 val2

Sets boundaries of x coordinate change for the plot. See also xrange.

MGL option: yrange val1 val2

Sets boundaries of y coordinate change for the plot. See also yrange.

MGL option: zrange val1 val2

Sets boundaries of z coordinate change for the plot. See also zrange.

MGL option: cut val

Sets whether to cut or to project the plot points lying outside the bounding box. See also cut.

MGL option: fontsize val

Sets the size of text. See also font.

MGL option: marksize val

Sets the size of marks. See also marksize.

MGL option: meshnum val

Work like meshnum command.

MGL option: legend 'txt'

Adds string ’txt’ to internal legend accumulator. The style of described line and mark is taken from arguments of the last 1D plotting (MGL) command. See also legend.
