FRAME COLOR

Name:
    ...FRAME COLOR
Type:
    Plot Control Command
Purpose:
    Specifies the color of the plot frame on subsequent plots.
Description:
    The frame is the 4-sided box which surrounds the usual 2-dimensional plot. The analyst can control the color of each or all of the sides of the frame by specifying the pre-fix in the command (see the SYNTAX section below).

    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 frame 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

Syntax 1:
    <prefix>FRAME COLOR <color>
    where <color> specifies the desired color;
    and     <prefix> is as follows:
      no prefix refers to all 4 sides
      the prefix X refers to both horizontal sides
      the prefix Y refers to both vertical sides
      the prefix X1 refers to the lower horizontal side
      the prefix X2 refers to the upper horizontal side
      the prefix Y1 refers to the left vertical side
      the prefix Y2 refers to the right vertical side.
Syntax 2:
    <prefix>FRAME 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 as follows:
      no prefix refers to all 4 sides
      the prefix X refers to both horizontal sides
      the prefix Y refers to both vertical sides
      the prefix X1 refers to the lower horizontal side
      the prefix X2 refers to the upper horizontal side
      the prefix Y1 refers to the left vertical side
      the prefix Y2 refers to the right vertical side.

    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.

Examples:
    FRAME COLOR YELLOW
    FRAME COLOR RED
    FRAME COLOR
    X2FRAME COLOR CYAN
    Y2FRAME COLOR MAGENTA
    FRAME RGB COLOR 220 109 88
    XFRAME RGB COLOR 175 238 238
Note:
    A ...FRAME COLOR command with no arguments reverts the setting to default. Thus X1FRAME COLOR with no arguments sets the bottom horizontal frame line color to black. A ...FRAME COLOR command with no prefix refer to all 4 sides. Thus FRAME COLOR GREEN sets the frame line color to green on all 4 sides. Note also that FRAME COLOR with no prefix and no arguments reverts the frame color settings on all 4 sides to default.
Note:
    Normally all frame lines are set to the same color, so the most common form of this command is FRAME COLOR with no prefix.
Default:
    All frame lines are black.
