Sets the line colors for a graph.


plotSetLineColor(&myPlot, colors)
  • &myPlot (struct pointer) – A plotControl structure pointer.
  • colors (String array) – name or rgb value of the new colors.


// Declare plotControl structure
struct plotControl myPlot;

// Initialize plotControl structure
myPlot = plotGetDefaults("xy");

// Set new line colors to aqua and midnight blue
clrs = "aqua"$|"midnight blue";
plotSetLineColor(&myPlot, clrs);

// Create data
x = seqa(0.1, 1, 50);
y = sin(x)~cos(x);

// Plot the data with the new line colors
plotXY(myPlot, x, y);


This function sets an attribute in a plotControl structure. It does not affect an existing graph, or a new graph drawn using the default settings that are accessible from the Tools > Preferences > Graphics menu. See the GAUSS Graphics chapter for more information on the methods available for customizing your graphs.
