how to change data such that graph is interrupted

I'd like to construct a graph like the following which is done with excel: enter image description here

I've entered my data into matlab using the following lines:

year = [1975 1976 1977 1978 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 ]

fix_No = [-9.449167466 -11.19432509 -8.500517848 -5.644813211 -2.608063866 2.614370892 6.461752833 7.035549084 8.542521755 12.11070577 6.476900841 8.029225388 4.315820526 4.165349512 5.34593031 7.510812752 -2.629044124 -5.713139529 -8.626773532 -11.83226415 . -8.821345246 -6.396197293 -5.187823611 -1.79008821 3.34099288 5.545228048 7.013763711 6.580524638 4.256524275 ]

fix_No_and_mean = [11.1610424 5.437315474 5.833032482 4.591658232 1.578021362 -1.572756298 -1.03351595 -2.250991302 -3.222969261 -5.734621837 . 12.96685642 10.95095066 10.2207684 5.654017602 1.753259697 -2.596143576 -7.155087995 -9.687001589 -8.700979283 -4.290434459 . 2.299711172 1.640802028 1.714407543 0.8360893 -0.425484303 -1.160053823 -0.858530711 0.123787867 0.782208621 ]

In 1985 and 1996 the lines should be interrupted as in the excel graph. But how can I do this using Matlab? I've put a "." (point) where the interruptions should be but matlab doesn't accept points. The lines for the construction of the graph look like this:

plot(year,fix_No, 'color', 'k', 'LineWidth',2, 'LineSmoothing','on')
line(year,fix_No_and_mean, 'color', 'r', 'LineWidth',2, 'LineSmoothing','on')
xlabel('year')
legend('fixed number', 'fixed number')

You Should put "NaN" instead of '.' ,i.e. in the places on the vectors fix_No_and_mean and fix_No that correspond to 1985 and 1996, put NaN.

This will plot different lines as in the figure you attached from excel.
