How to visualize high dimension data separated by LDA

Hi, I'm trying to show how data clusters shift over multiple days. I have a 9 class problem in a 40 dim space and I use LDA ([results, error,POSTERIOR,logp,coeff] = CLASSIFY(SAMPLE,TRAINING,GROUP)) as my classifier. I would like to project the data to 2 and 3 dims, using the linear discriminants LDA finds (the ones that provide best separation). I've already done it with PCA, but that does not provide the results I need.

Thank you for your help!
