How can I save a plot with closed boxed area in MATLAB?

Question

How can I close the plot area with black lines in the top and right side when I save a plot?

I don't have any idea how to make it or how to search, if anyone knows please tell me.

For example look at the plot shown below, where the lines are missing:

Answer 1

Before you save your image, use the box command. This will enclose your plot to have the surrounding black box as you have specified in your example image. Simply call:

box on;

To turn it off, do:

box off;

Example:

%// Plot a line from 1 to 5 for x and y
x = 1:5;
y = 1:5;
plot(x,y);
box on;

This is what the plot looks like:

If you were to turn boxing off, this is what the plot looks like:

box off; is the default behaviour for plot, as you have seen in the example image you have shown. Simply call box on; after the plot is shown and before you save your image to get the desired effect.
