LPLOT

PLOT command that cycles through line styles.

LPLOT(X,Y) plots Y versus X just like the PLOT command but cycles through 12 different line styles instead of colors (4 line styles x 3 line widths). The axes LineStyleOrder is set to '-|:|--|-.' and axes ColorOrder is set to [0 0 0]. Multiple data sets, accepted by PLOT, are allowed. e.g. LPLOT(X1, Y1, X2, Y2, ...) or LPLOT(X, [Y1, Y2, ...])
H = LPLOT(...) returns a vector of line handles.

Example:
x = (0:0.1:10)';

y1 = 1.2 * sin(x);
y2 = 0.7 * cos(0.3 * x);
y3 = 2 * sin(0.7 * x);
y4 = y1 + y2;
y5 = y1 + y3;
y6 = y2 + y3;
y7 = y1 - y2;
y8 = y1 - y3;
y9 = y3 - y2;
y10 = y1 .* y2;
y11 = y1 .* y3;
y12 = y2 .* y3;

h = lplot(x, [y1, y2, y3, y4, y5, y6, y7, y8, y9, y10, y11, y12]);
legend(h, ...
