compare function plot: hopelessly monochrome

Hi, I'm trying to print to PDF a system response comparison plot obtained by using the compare(data,sys1,...,sysN,prediction_horizon) function, but when it comes to printing (even to PDF) I can't manage to have a coloured image.

The steps I tried so far: when i click on Print, I select the Appearance tab and check the "Color" radio button (while at first the Monochrome radio is selected and, suspiciously, greyed), nevertheless the .ps file always generates a B\W figure. Could it be a renderer-related issue?

Did you try the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions.

yep, with no success because actually the plot is open in the system comparison environment, which is not itself a figure (thus not allowing to use export_fig.

Btw I was able to figure it out with the following steps:

1. click on the "add legend" button inside the compare plot window
2. right click on the legend box, choose "Show Property Editor"

This will open the plot as an actual figure, which will allow you to see the button "Export setup.." where you can actually specify the output format. For example EPS and PDF will produce coloured images.
