Plotting a 3D surface from measurement datas

Hello,

I am relatively new to Matlab and am currently trying to generate a 3D plot from multiple measurement data.

The task is the following:

Data series:

x = Boiler 1 %Name of the object.

y = [0 1.4 1.5 2 3] %Random time points

z = [300 323 345 500 255] %Recorded temperature

x = Boiler 2 %Name of the object

y = [0 1 2 3] %Random time points

z = [100 200 300 400] %Recorded temperature

...

This data can now be easily processed with the plot3 function. However, these are to be seen then accordingly only as line function.

I would like to unite these line functions now to a surface (like with surf).

So far I could not find an appropriate solution for this and hope that someone can help me here?

The data of the measurement series come from Excel. Is there also here a more elegant way than to implement these manually?

Many thanks and greetings

I suspect the griddata function would do what you want to create the surface from your vectors, however I have no idea what your data actually are.

Thank you for your answer, i will give it a try.

As always, my pleasure!

Note that ‘x’ needs to be a numeric array, not a character vector.

With more data, I could provide a more definitive solution. It should be possible to produce the surface you want, or at least a close approximation to it.
