Plot of 4 variables with dates(years)

Hello everyone! I need some help on a plot. I need to put in a plot 4 cumulative returns(CS1,CS2,CS3,SC4) on axe y, with variable date 1990,1993,1996,2000,2003,2006,2010,2013,2016 and 2020 on axe x for four strategies P1,P2,P3,P4.

ylabel({'Cumulative return'});
xlabel({'Date'});
title({'Cumulative returns of the portfolios'});
Legend({'P1','P2','P3','P4'});

You should read the documentation of plot():

https://www.mathworks.com/help/matlab/ref/plot.html

All you need is to define cumulative return of the four series in columns.

CumulativeReturn = [
	5   4   1   6
	14  9   4   16
	26  17  14  31
	40  34  29  55
	61  59  52  80
	66  63  53  86
	75  68  56  96
	87  76  66  111
	101 93  81  135
	122 118 104 160];

Years = [1990;1993;1996;2000;2003;2006;2010;2013;2016;2020]; 

PlotHandle = plot (Years, CumulativeReturn); 

set (PlotHandle, {'DisplayName'}, {'P1';'P2';'P3';'P4'});
set (PlotHandle, {'LineWidth'},   {2;2;2;2});

xlabel ('Years'); 
xticks (Years);
ylabel ('Cumulative return');
title  ('Cumulative returns of the portfolios');
legend ('Location', 'Northwest');
