Change opacity of Lines
Hello everyone
I want to change the opacity of lines I plotted in a figure in MATLAB. I read somewhere about alpha and facealpha commands but couldn't figure how to use them. Could somoene please tell me how to do this?
Regards Adi

It is not possible to set the transparency of lines.
The workaround is to use very thin patches instead of lines, as you can change the EdgeAlpha property for patch edges, or the FaceAlpha property of patch faces; see http://www.mathworks.com/help/techdoc/ref/patch_props.html

In newer versions of MATLAB you can do that easily using the Color property of the line.
By default it is RGB array (1 x 3). Yet if you set it to RGBA (1 x 4) the last value is the alpha of the color.
Enjoy...
