How do I colour data points in PCA according to colours in cluster analysis?

Hi, I performed a cluster analysis and coloured the clusters. In a subsequent PCA, how can I apply the colouring from the hierarchical cluster analysis to the data points in the PCA? Thanks so much for your time. Andreas

Re: Colour data points in PCA according to colours in cluster analysis

That seems to be happening for me automatically.

I did a cluster analysis and chose Color Clusters from the red triangle menu.

Then when I choose Analyze -> Multivariate Methods -> Principal Components, the Summary Plots and Biplot are colored by the clusters.

Can you give us some more details on what you've tried and what plots aren't colored as you'd like?
