Loop plotting for individual years

I am trying to plot the average ice concentration on y axis and the date from december 1 st to 30 of march for each year. (10 individual plots for each year ) I donot know how to do, I assume I wil need to use a loop to start from 2011 to 2011. I would want the plots to show the gaps of the missing dates. where on x axis dates from 1st of december to 30 march for each year and y axis the avaiable average ice concentrations for each year period. The code is as below . Any recommendation or help will be appreciated.

T1 = readtable("Ice concentration data.csv")

T1.DateTime

VN = T1.Properties.VariableNames;

lgdstr = cellfun(@(x)strrep(x,'_','\_'), VN(2:end), 'Unif',0)

figure

plot(T1.DateTime, T1{:,2:end})

grid

legend(lgdstr, 'Location','best')

What are the 10 plots for each year?

On the x axis the date from december 1st to march 30 abd y axis the average ice concentration for that period. But not all dates in these period are on csv file. I still want it to show december to march on axis, and themissing y values as no markers

There's no legend in the example below, because I am not sure what you wanted to do with the cellfun function.

Nevertheless, it should help.

T1 = readtable("Ice concentration data.csv");
allyears = unique(year(T1.DateTime));

for yrs = 1:length(allyears)
idx = year(T1.DateTime)==allyears(yrs);
figure(yrs)
plot(T1.DateTime(idx), T1{idx,2:end})
grid on
end

 g = findgroups(ymd(T1.DateTime));

Now you can splitapply() some plotting code on elements of your table using groupping variable g
