From: M K on 2 Oct 2009 06:21 Hi , I am using the mesh function to plot some wave field distributions in materials. I realised however, that some of the intricate parts of the field strengths a;hough present are not clear enough. I was wondering if there is some way I can increase the intensity of the color scale or perhaps use a different plotting function which provides more pronounced intensities? I've tried the contourf function but that seems to provide very little detail. Mesh seems to provide the best so far but only need some more weight on the small intensities. Any suggestions would be most useful. thanks for your help mesh(x,y,z)

From: M K on 2 Oct 2009 06:37 Thanks Rune, shading interp under contourf gives me a warning (Warning: Color Data is not set for Interpolated shading) and doesn't plot anything in the figure window. However surf followed by shading interp gives the same result as mesh(x,y,z). Any way i can increase the intensity of the colour scale? thanks again.

Find out how to use adapt your data so that SURF or CONTOURF work. Then use SHADING INTERP or SHADING FLAT. Rune

Use the fourth input argument, C, in your call to MESH; change the figure Colormap (using the COLORMAP function); and/or change the mesh's CData and CDataMapping properties. http://www.mathworks.com/access/helpdesk/help/techdoc/ref/surface_props.html#CData -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ |
