在八度中绘制四边形面

Question

I have the coordinates (X,Y and Z) of 4 points, (not necessarily lying on the same plane and not necessarily a rectangle!) and I want to plot this quad face in octave.

I used the following plot function

plot([x1 x2 x3 x4], [y1 y2 y3 y4], [z1 z2 z3 z4], '-')

but it didn't work.

I'd like to have as a result, not a wireframe plot (ie only the edges plotted) but the whole surface.

Any suggestions?

Thanks!

Edit: I edited my question, because I'd like to know if it is possible to achieve a contour "less continuous" (see following images).

The result I get is the following image. Contour continuous

I'd like instead to get a less continuous contour, in which I can clearly see the boundaries between the different coloured parts (see following image).

Desired result

Any suggestions?

Thanks
