Creates line plots. In particular, this function is used when the data sets are sampled on different position vectors.

Description |
|---|---|
|
out = plotxy(x,y); |
Creates a plot of y vs x, y and x are both 1D vectors with the same length. The figure number is returned. |
|
plotxy(x1,y1,x2,y2,xn,yn); |
Creates a plot with multiple curves. The xn-yn pairs must have the same length, but x1, x2, and xn can have different start-end values and resolutions. The figure number is returned. |
|
plotxy(x1,y1,x2,y2, "x label", "y label", "title"); |
Creates line plots with axis labels and a title, returns the figure number. |
Example
This example will generate a figure with two functions with different resolutions:
x1=linspace(0,2*pi,15);
y1=sin(x1);
x2=linspace(1,pi,3);
y2=x2/2;
plotxy(x1,y1,x2,y2,"x","y","title");
legend("y1=sin(x1) - 15 pts","y2=x2/2 - 3 pts");
The following figure shows the output of the the example code.
