Examples#

Example 1: Basic usage with string names#

// Declare plotControl structure
struct plotControl myPlot;

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

// Set line 1 as a solid line, line 2 as dashed
plotSetLineStyle(&myPlot, "solid" $| "dash");

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

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

Example 2: Using numeric values#

// Declare plotControl structure
struct plotControl myPlot;

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

// Set line 1 as solid, line 2 as dash,
// line 3 as dot, line 4 as dash-dot, line 5 as dash-dot-dot
plotSetLineStyle(&myPlot, seqa(1, 1, 5));

// Create data
x = seqa(0.1, 0.1, 50);
y = sin(x)~cos(x)~sin(x+1)~cos(x+1)~sin(x+2);

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