Zdata(N,1) to RGB Cdata(N,1,1:3)

3 views (last 30 days)
I have lat, long, and skill vectors. All vectors are (n,1). (skill ranges from 0.0 to 1.0)
for j = 1:n_validlength;
plotm(Lat_NCOMwCodar(j),Lon_NCOMwCodar(j),0,'Marker','s','MarkerSize',12,...
'MarkerFaceColor',skill_color_NCOMatCodar(j,jj,:));
end
where skill_color_NCOMatCodar(j,jj,1:3) is colormap('jet') from skill_NCOMatCodar(j,jj)
How to set the relationship between SKILL(n,jj) range 0.0 to 1.0 to SKILL_COLOR(n,jj,1:3) ?
I can not use contourm, geoshowm, because data is not at i,j mesh, image. Ilregular grids are used.

Solved my own question:
cmap_jet = colormap(jet(64)); % used colormap 'jet' with 64 colors
for j = 1:n
if skill(j) == 0;
skill_color(j,:) = ([0 0 0]); % set to black
else
% return index from 1 to 64 based upon skill level (data) from 0.0 to 1.0
% note: skill.*number_of_colors_in_colormap
% note: goal: return indexes from 1 to 64 starting with data range.
skill_color_idx(j) = uint8(ceil(skill(j).*64));
% now return cmap_jet row :RGB as color of skill
skill_color(j,:) = cmap_jet(skill_color_idx(j),:); % jet colors
end
end
