How to make a break on x axis and have two sets of values?

hi i have to plot a graph where im given the daily temperature for five lakes for a year (366 days). we are asked to make a graph for winter days only (days 1 to 79 and days 355 to 366) with all 5 lakes on one graph. i know that if i want to make a graph for the whole year with all the lakes on one graph i have to do:

x=[1:366];
y=[1:366];
y1= lakeerie
y2= lakehuron
y3= lakemichigan
y4= lakeontario
y5= lakesuperior
plot(x,y1,x,y2,x,y3,x,y4,x,y5)
ylim([0 25])

where x represents the days and y represents the temperature in degree Celsius

but how do i only show the values for days 1 to 79 and days 355 to 366?

You need to read this article on indexing: https://www.mathworks.com/company/newsletters/articles/matrix-indexing-in-matlab.html

indx1 = 1:79;
indx2 = 355:366;
figure; hold on;
plot(x(indx1),y1(indx1),...);
plot(x(indx2),y1(indx2),...);

There are plenty of submissions in the File Exchange for plots with broken axes (skips or gaps in the axis):
