i want to plot this on matlab. the code i am trying is
[~,~,v]=xlsread('solarg55.xlsx')
v=v(2:end,:);
x=datenum(v(:,1),'dd/mm/yyyy HH:MM:SS')
y=cell2mat(v(:,2))
[idx,idx]=sortrows([x,y])
plot(x(idx),y(idx))
xticks=get(gca,'Xtick')
set(gca,'xticklabel',datestr(xticks,'dd/mm/yyyy HH:MM:SS'))
but it gives me this error
Error using date
Too many input arguments.

Not sure exactly what your desired outcome is. However, why not use readtable, which loads your data into a table? It can handle your dates automatically as datetimes. When you plot with a datetime, the axis labels are dates. No need to set the label manually. You can also sort a table.
Try this code:
opts = detectImportOptions('solarg55.xlsx');
data = readtable('solarg55.xlsx',opts);
data.Properties.VariableNames = {'X','Y'};
data = sortrows(data,{'X','Y'});
plot(data.X,data.Y)
