How to do this temporal plot

HI,
I have time series data for a parameter for multiple sites like this graph shows. What function do I use? Also, I like making a table of data in excel and then importing it into the script so how is it best to format the table? Thanks

Here's one way.
For importing data, perhaps something like data=transpose(readmatrix('filename.xlsx',Range','A2:N2002'));
Empty cells should be imported as NaNs then.
% Generate fake data
data = 2*rand(14,120);
for idx = 1:14
data(idx,1:randi(70)) = nan;
end
% Plot it, beginning at year 1901
xx = 1900+[1:size(data,2)];
interestingPlot(xx,data)
function interestingPlot(xx,data)
yy = 1:size(data,1);
f = pcolor(xx,yy,data);
shading flat
colorbar
% Shift the bins
f.XData = f.XData-.5;
f.YData = f.YData-.5;
ax = gca;
% Shift the axes
ax.XLim = ax.XLim-.5;
ax.YLim = ax.YLim-.5;
% Flip the y axis
ax.YDir = 'reverse';
xlabel('Date')
ylabel('Site')
colormap (flipud(hot))
end

No problem. I edited the code to turn it into a function, in case you need to generate this kind of plot often.
