GRID COLOR

...GRID COLOR

Plot Control Command

Specifies the color of the grid lines on subsequent plots.

The analyst can independently control the color of the horizontal and vertical grid lines by specifying the pre-fix in the command.

Dataplot provides two methods for specifying colors.

1. Colors can be defined by name (or by the corresponding index). Dataplot adopted it's named colors from the X11 project. Currently, 162 named colors and 100 levels of grayscale are supported. Grayscale can be specified with either G0, G1, ..., G100 (or -1, -2, ..., -100). Many older devices support only a limited number of colors. For these devices, unsupported colors will be mapped to one of the available colors. To specify a named color, see Syntax 1.

2. Most modern graphics devices support full RGB (RedBlueGreen) color. You can alternatively specify RGB colors by entering three integer values to represent the Red, Green and Blue components, respectively. These values should be in the range 0 to 255.

When setting the grid RGB color, Dataplot first checks if the device supports RGB colors. If not, the named color will be used. If the device does support RGB color, Dataplot will check if an RGB color has been specified. If yes, then that RGB color is used. If not, the named color will be used.

To see the list of supported named colors (with the associated index number), see

<prefix>GRID COLOR <color>
where <color> specifies the desired color;
and     <prefix> is one of the following:

no prefix refers to both grid lines
the prefix X refers to vertical grids
the prefix Y refers to horizontal grids.

<prefix>GRID RGB COLOR <red> <green> <blue>
where <red> is an integer number or parameter that specifies the red component;
            <green> is an integer number or parameter that specifies the green component;
            <blue> is an integer number or parameter that specifies the blue component;
and     <prefix> is one of the following:

no prefix refers to both grid lines
the prefix X refers to vertical grids
the prefix Y refers to horizontal grids.


To turn off the RGB color, set the values to -1 (any negative value will work). Values greater than 255 will be set to 255.

The GRID COLOR command with no arguments reverts the grid color to default.

The default is black (but the default is for the grid lines themselves to be off.)
