Hello Izabela,
The current colormap is always stored as a figure's property, as shown
for instance in the examples at
https://help.scilab.org/docs/6.1.1/en_US/colormap.html
Here is a possible implementation (without the gsort stuff):
X = [0.5 1.5 1.5 ; 1.5 2.5 1.5];
Y = [0.5 1 1 ; 1 0.5 2];
Z = [0 1 1 ; 1 2 3];
clf
param3d1(X,Y,Z);
h = gca().children(1).children;
ccm = gcf().color_map;
ncurv = size(X,2);
ncol = size(ccm,1);
// proposal : extending the current color map, instead of replacing it:
gcf().color_map = [ccm ; jetcolormap(ncurv)];
h.thickness = 4;
h.foreground = ncol+(1:ncurv); // "vectorized"assignment allowed. for loop
not required
Hope this helps.

Hello,
I need some help with a param3d1 graph. Each polyline should have
color from a colormap according to the value assigned in a T vector.
Here is a simple example (not finished):
X=[0.5 1.5 1.5 ; 1.5 2.5 1.5];
Y=[0.5 1 1 ; 1 0.5 2];
Z=[0 1 1 ; 1 2 3];
T=[2 1 3];
[sorted_T, index_sort_T]=gsort(T , 'g' , 'i');
colors=zeros(size(T , 'r');
colors(index_sort_T , :)=jetcolormap(size(T , 'r');
param3d1(X,Y,Z);
h=gca().children(1);
h.children.thickness=4;
for i=size(T,'r')
h.children(i).color=???
end
Instead of question marks there should be a color index, but I don't
know how to define it using jetcolormap.
I would be grateful for your kind help,
