MATLAB: Do the axes for the BODE plot in the Control System Toolbox 5.2 (R13) and later versions overlap when I print to a postscript file

anglebodeControl System Toolboxepsfigurephaseplotpostscriptprintvalues

For example:

s=tf('s');
bode(s/(s^2+0.2*s+1))
print -deps bode.eps

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in MATLAB in the way that the BODE function prints to a postscript file.

Currently, to work around this issue, try printing the BODE plot to a graphic image file such as a JPEG or TIFF file.

For example,

print -dtiff bode.tif

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

We have verified that there is a bug in the Control Systems Toolbox 6.1 (R14SP1) in the way that Bode plots are printed from the LTI Viewer.

To work around this issue, try using the following code:

set(0,'showHiddenHandles','on');

Then select the LTI Viewer to make it the current figure and enter the following command to send the window to the printer:

print

Where do these lines appear? When printed to paper or when displayed to the screen?

For the later see: http://www.mathworks.com/matlabcentral/answers/15388-artifacts-in-figures-exported-as-pdf-from-matlab If you have two neighboring areas in a PS or PDF and display them with antialiasing, a small line with the background color must appear between the edges. There is simply no optimal choice.

This is a general problem of vector formats. Even the pixel-graphics created by OpenGL miss some points on the edges under rare conditions.
