hi, i was searching for getting projection of plots in 3d view, i found a nice shadowplot function for this purpose i am trying to use it for 3d vectors after plot3(..) but not successful. it only works with mesh/surf plots. help

aH = axes; your_data = randn(1000,3); oneMat = ones(size(your_data,1),1); plot3(your_data(:,1),your_data(:,2),your_data(:,3),'b.'); hold on xL = get(aH,'XLim'); yL = get(aH,'XLim'); zL = get(aH,'XLim');

plot3(oneMat .* xL(2), your_data(:,2), your_data(:,3), 'k.'); plot3(your_data(:,1), oneMat .* yL(2), your_data(:,3), 'k.'); plot3(your_data(:,1), your_data(:,2), oneMat .* zL(1), 'k.');

I don't understand, what's wrong with the way I plotted it? Could you please show an example of what you actually want?

let's say i have to plot a sin and cos in complex plan with their shadows on the walls t = 0:pi/50:10*pi; plot3(t,cos(t),sin(t)); if i apply shadowplot x or shadowplot y nothing happens...

That's because you are talking about points. The "shadow" of a point is a point, the "shadow" of a surface is a surface.

What about using `surf` instead of `plot3` when the function you have found works for `surf`, but not for `plot3`? There are a lot of examples for surface plots in the FileExchange, search for e.g. "arrow".

Please mention any details about the "nice shadowplot function" you have found. We cannot guess which function this is.
