principal component analysis in MATLAB

Hi, everyone
Recently I performed PCA in MATLAB for discrimination analysis, and the matrix data for PC1, PC2 and PC3 were calculated, finally for data visualization, the comparisons of PC1 vs. PC2, PC2 vs. PC3, PC1 vs.PC3 were processed in MATLAB graph functions(scatter function), and the figures are OK, like the following picture, but the original dream of specified label of each point-element name, such as Fe, Mg, Zn, in this application-is not available, is there some tips or solutions for this issue, thanks in advance!
