Trying to create a plot with a line as shown in the pictures

my code: im using a for loop to create a graph and plot as it works out but i can only get the graph to look like the first pic below, what would be the lines of code to get it to look like the second graph? (just one line ofcourse i couldnt find another one on the internet) thanks for the help!

figure(1)

plot(t,Tin,'--xb')

title('Room temperature over time for Tlower=21^oC and Tupper=24^oC')

xlabel('Time(s)')

ylabel('Temperature(degrees)')

hold on

vague....

what else do you need to know all im asking for is a 1 line code to give me a line instead of points?

[Jan]

It is not clear, why

plot(t,Tin,'--xb')

does not create a continuous line, but only the x markers. Does Tin contain NaNs?

[barry conrad]

i dont think Tin contains NaNs but i choose to plot as i go instead of an array

[Jan]

Instead of thinking, simply check if it contains NaNs:

any(isnan(Tin))

What does "i choose to plot as i go instead of an array" mean? Of course, if you create the diagram by calling plot in a loop, you cannot get a line. So please post exactly the code you use and provide the input data.

use 'b' as marker instead of 'x'

doesnt work,graph shows up completely blank

Then upload the data file to break it down...
