Edit Item Colors

Controls: Edit Menu >> Colors & Line Styles >> Item Colors
Macros: Color, ColorNum

To change the color of an item (Screen, Grid, Cursors, Left In, Right In, Left Out, or Right Out) click on its button here first. The colored square to the left of each button shows the current color. Then either adjust the Red, Green, Blue controls to change it, or click Palette to get the standard Windows Color selection dialog.

Macro Notes:

Normally, you will probably want to use the ColorNum command to set colors directly, without first selecting an item and then giving separate commands to set Red, Green, and Blue. For example, ColorNum#L=h00FF00 sets Left Input to pure green. The value given may be a constant (as here) or a variable or expression. Values will be limited to 24 bits (0xFFFFFF or 16777215).

Please note that the Edit Color - Red, Green, Blue buttons are shown in the conventional RGB order, while Windows colors (and ColorNum) use the reverse order. For example, hFF0000 is pure blue, and h0000FF is pure red.

The single character after the # specifies the item to be changed:

    S = Scrn
    G = Grid
    C = Curs
    L = LI
    R = RI
    l = LO
    r = RO
    c = Ch select color

If you use the c option, the current channel number 0-3 previously set via Channel Select Ch is used to set the color of LI to RO, respectively.

Conversely, you can read any of these color values, or use it in an expression, by using ? in place of #, as in X=ColorNum?c. This is convenient for setting Macro Array display colors to match main trace colors.

To use macros to emulate the manual operation of selecting an item before adjusting its color, use Color=Scrn, Color=Grid, Color=Curs, Color=LI, Color=RI, Color=LO, or Color=RO.

Alternatively, instead of names like Scrn you can use numeric values, variables, or expressions for setting, reading, or IF testing:

    0 = Scrn
    1 = Grid
    2 = Curs
    3 = LI
    4 = RI
    5 = LO
    6 = RO
