Examples

// Declare plotControl structure
struct plotControl myPlot;

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

// Set all bars to have a solid, blue, fill, with 50% opacity
textures = 1;
plotSetFill(&myPlot, textures, 0.5, "blue");

// Create data
x = seqa(1, 1, 5);
y = { 1.5, 2, 3, 0.5, 1 };

// Draw bar graph
plotBar(myPlot, x, y);

Remarks

When graphing without the use of a plotControl structure, these settings may be chosen by selecting Tools > Preferences > Graphics > Profiles from the main menu.
