MATLAB: Add uncertainty interval time-series

time series

Hi,

I have time-series data of temperature along time.

I have plotted the data on a simple graph.

How can I make a band around the time-series temperature data on the graph to show a 0.1 ◦ C uncertainty in air temperature?

What code do you suggest?

Thank you.

Depending on the plot resolution, it could be difficult to see easily.

Try this:

time = linspace(0, 20);
temp = 20+10*sin(2*pi*time/15);
figure
plot(time, temp)
hold on
patch([time fliplr(time)], [temp fliplr(temp)+0.1], [0.8 0 0], 'EdgeColor','none')  % Plot +0.1 C Band
hold off
grid
ylim([0 35])
