Dear all,
I used this function in Matlab FEX to draw a Taylor diagram. I really need to change the color of generated markers to some hex colors. Since this function won't accept hex color I want to ask you professionals Is there any way to change the color of each marker to hex colour after I draw? I hope Matlab could save my life again.
load('taylor_data.mat');
% Calculate statistics for Taylor diagram
% The first array element corresponds to the reference series for the
% while the second is that for the predicted series.
taylor_stats1 = taylor_statistics(pred1,ref,'data');
taylor_stats2 = taylor_statistics(pred2,ref,'data');
taylor_stats3 = taylor_statistics(pred3,ref,'data');
% Store statistics in arrays
sdev = [taylor_stats1.sdev(1); taylor_stats1.sdev(2); ...
taylor_stats2.sdev(2); taylor_stats3.sdev(2)];
crmsd = [taylor_stats1.crmsd(1); taylor_stats1.crmsd(2); ...
taylor_stats2.crmsd(2); taylor_stats3.crmsd(2)];
ccoef = [taylor_stats1.ccoef(1); taylor_stats1.ccoef(2); ...
taylor_stats2.ccoef(2); taylor_stats3.ccoef(2)];
% Produce the Taylor diagram.
%
% Note that the first index corresponds to the reference series for the
% diagram. For example sdev(1) is the standard deviation of the reference
% series and sdev(2:4) are the standard deviations of the other series.
% The value of sdev(1) is used to define the origin of the RMSD contours.
% The other values are used to plot the points (total of 3) that appear in
% the diagram.
[hp, ht, axl] = taylor_diagram(sdev,crmsd,ccoef);
I want to change red circules to 3 different colors using hex colors.
Thank you all.

This should be a start
load('taylor_data.mat');
% Calculate statistics for Taylor diagram
taylor_stats1 = taylor_statistics(pred1,ref,'data');
taylor_stats2 = taylor_statistics(pred2,ref,'data');
taylor_stats3 = taylor_statistics(pred3,ref,'data');
% Store statistics in arrays
sdev = [taylor_stats1.sdev(1); taylor_stats1.sdev(2); ...
taylor_stats2.sdev(2); taylor_stats3.sdev(2)];
crmsd = [taylor_stats1.crmsd(1); taylor_stats1.crmsd(2); ...
taylor_stats2.crmsd(2); taylor_stats3.crmsd(2)];
ccoef = [taylor_stats1.ccoef(1); taylor_stats1.ccoef(2); ...
taylor_stats2.ccoef(2); taylor_stats3.ccoef(2)];
% Produce the Taylor diagram.
[hp, ht, axl] = taylor_diagram(sdev,crmsd,ccoef);
% convert a hex tuple
hexcolor = 'FE230A';
deccolor = hex2dec(reshape(hexcolor,[],2)).'/255
for kc = 1:numel(hp)
set(hp(kc),'MarkerFaceColor',deccolor,'MarkerEdgeColor',deccolor)
end
If you want to have a different color for each marker, you can just move the conversion process inside the loop.

You should be able to change the color of the points by using the hp output:
set(hp(1),'color',[0.95,.3,0.1])
set(hp(2),'color',[0.32,0.1,0.9])
set(hp(3),'color',[0.1,1,0.43])
Check the help and documentation of the function for more information.
