octave plot legend
To add a legend to a plot in MATLAB or Octave, you can use the legend
function. Here's an example:
x = 1:10;
y1 = x;
y2 = x.^2;
plot(x, y1, 'r', x, y2, 'b');
legend('y = x', 'y = x^2');
In this example, we create two lines (y = x
and y = x^2
) and plot them using the plot
function. The 'r'
and 'b'
arguments specify the colors of the lines. The legend
function is then used to add a legend to the plot, with the labels 'y = x'
and 'y = x^2'
.
