Plot options and their defaults are shown below.
The defaults are set whenever you use the 'reset' or 'new' commands and are defined in script ~system\classes\plot\plotdefs.ijs.
To customize the defaults, create a script with the same name in your config directory, i.e. with name ~config\plotdefs.ijs, and enter any changed default options. For example, to default to axes without frames or grids, enter the following into your plotdefs.ijs script:
AXES=: 1 FRAME=: 0 GRIDS=: 0Options are specified by providing the option name followed by its argument. Several options can be given at one time, separated by semicolons. Option values are stored as uppercase global variables.
Options whose names begin with 'x' apply to the x-axis; similar options apply to the y and z axes.
