difference between surface and mesh plots

Please let me know what is the difference between wire frame mesh plots and surface plots ?

Answer 1

[Walter Roberson]

Surface plots use Primitive Surface Objects http://www.mathworks.com/help/matlab/ref/primitivesurface-properties.html

Mesh use Chart Surface Objects which I had never heard of before. http://www.mathworks.com/help/matlab/ref/chartsurface-properties.html

My phone interface is too limited to figure out the differences.

[Walter Roberson]

The difference between chart objects and the "primitive" object of the same category is that the chart objects have additional information about source variables to allow the plots to be automatically updated as the variables change.

• If you want to plot a 3D figure similar to Short Time Fourier Analysis, like spectrogram(), surf() should be used.
• Once I want to plot something related to STFA, the cross section view changes according to the view angle. That is to say, the bottom-up view is different from the up-bottom view. Then I used surf() instead, both views are the same.
• I do not know the specific reasons and I can not understand the help info given by Matlab.
