MATLAB: Display time in the title

num2strplottimetitle

Hey.

I would like to ask whether it´s possible to display a timestamp in the title? Let me make a eksampel:

you can write in your m-file: title(['temperture ',num2str(max(temp)), '[deg]'])

then the max temperture will display in the title.

Is it possible to display the time in the title when the temperture hit the "max" also? (eg. 100 s)

Thank you

If you can find the max temperature, you can use the index to find the time.

[MaxTemp,Index]=max(temp); TimeAtMaxTemp=time(Index);

Where time is your time vector. Then you can use same num2str() technique to display it in the title.

MATLAB: Plot extreme values on a time series

Use the max and min functions with two outputs to get the first instance of the maximum and minimum. Then use the second (index) output to find the value of time where it occurred:

[ymax,maxidx] = max(y);
[ymin,minidx] = min(y);
figure(1)
plot(time, y)
hold on
plot(time(maxidx), ymax, '^r')
plot(time(minidx), ymin, 'vr')
hold off
grid

If you have more than one values for the maximum or minimum, use the find function:

maxidx = find(y == max(y));

and the plot calls then change to:

plot(time(maxidx), y(maxidx), '^r')

and the same for the minima.

NOTE — This is UNTESTED CODE but should work.
