Examples#

// Clear out variables in GAUSS workspace
new;

// Create data
x = seqa(-4, .125, 161)';
y = seqa(-8, .125, 161);
z = sin(x) .* cos(y) * .5;
z = z .* sin(x/3) .* cos(y/3);
z = z .* sin(x/5) + sin(y/2.5)/3 + sin(x/2.5)/3;

// Set up control structure with defaults
// for surface plots
struct plotControl myPlot;
myPlot = plotGetDefaults("surface");

// Set title and Z axis label
plotSetTitle(&myPlot, "Contour plot example", "arial", 16, "black");

// Set color map for contour
plotSetColormap(&myplot, "viridis");

// Draw graph using plotcontrol structure
plotContour(myPlot, x, y, z);

The plot is
