Hi I have a biplot with the PCA results from 9 houses and 14 variables. I am trying to label my scores with the correspondent chemical name. I am using the following code but matlab is giving me this error message. I already tried to transpose my cells and no luck. Any guidance will be appreciated.
Thanks
Z = zscore(spw); % Standardized data
[coefs,score,v,g,ex] = pca(Z);vbls = {'1','2','3','4','5','6','7','8', '9'}; % Array of variable labels for houses
Pah={'Naph','2Methyl','1Methyl','Acy','Ace','Flu','Phe','Ant','Flt','Pyr','BaAnt', 'Chr', 'BbFlu','BkFLu','BePyr'};% chem names
h6 = biplot(coefs(:,1:2),'Scores',score(:,1:2),'ObsLabels',Pah, 'VarLabels', vbls);Error using biplot (line 219)'ObsLabels' value must be a character array, string array. or cell array of character vectors with one labelfor each row of the 'Scores' matrix.
