bug in plot3d2?

[Gianluca Antonelli]

Hi,

there is a strange behavior of the color feature using plot3d2.

When I use the following code:

h=gca();
h.axes_reverse(3)="on";

within an existing graphic made with plot3d2 the former color settings 
are lost.

To reproduce it just add those two lines to the code of the help:

// code from help plo3d2
u = linspace(-%pi/2,%pi/2,40);
v = linspace(0,2*%pi,20);
X = cos(u)'*cos(v);
Y = cos(u)'*sin(v);
Z = sin(u)'*ones(v);
plot3d2(X,Y,Z);
e=gce();
e.color_mode=5; // change color
//end code from help plot3d2
h=gca();
h.axes_reverse(3)="on";


Best,
Gianluca
