With this one could plot a filled contour graph and over-plot with an area graph which grey-ed out non-significant areas whilst leaving the significant areas un-touched. The bright sparks have now taken away the FaceAlpha property of area plots (areaseries), presumably wanting us to go in with primitives (like patch) and render each polygon in the area under a complex curve to be transparent (what a great improvement!). Any ideas how to do this with a minimum of fuss? On matlab 6.5.1 one could draw an area plot and set the FaceAlpha to give a transparency.

'FaceAlpha',0.4,'FaceLighting','phong'); % X1,Y1,Z1 data is positive *********************************************************** The problem is that my XScale looks like 'log' but the surface looks like the XScale where 'lin'. In other words, if I change the XScale from 'log' to 'lin', the surface does not change, it does not react to XScale. However, this is only valid for XScale. If I do not change Renderer to 'OpenGL' than everything works fine but than the plot loses its transparency by changing any 'lin' scale to 'log'. Hi All, I have following problem:

For my 3D plot in Matlab I use
set(gcf, ‘Renderer’, ‘OpenGL’) to maintain the transpparency of the surface independent of XScale type (see below):

************************************************
figure;
hold on;
set(gcf, ‘Renderer’, ‘OpenGL’);
set(gca, ‘XScale’, ‘log’);
view(3);
surf(X1,Y1,Z1,’FaceColor’,'red’,'EdgeColor’,'none’,…
‘FaceAlpha’,0.4,’FaceLighting’,'phong’);

% X1,Y1,Z1 data is positive

***********************************************************

The problem is that my XScale looks like ‘log’ but the surface looks like the XScale where ‘lin’. In other words, if I change the XScale from ‘log’ to ‘lin’, the surface does not change, it does not react to XScale. However, this is only valid for XScale.

The copied plot either has very bad resolution or lose the transparency of pacthed area . I tried differrent ways, e.g. copy it directly from MATLAB, save or print it in eps, jgn,jpg,emf .... they just did not work. I have two question about this fucntion

Check the renderer
>>get(gcf,’renderer’)

Make sure it is openGL. That is the only renderer in MATLAB that supports transparency. I suspect it got changed and that is why you lost the effect.

Is ther a way to keep the tranparency even after changing the scale to logarithmic from plot window.
