I want to plot my data for PCA.

For ex/ I have 100\*50 matrix.

Im now sure, but may be we can consider the column as the feature (feature = 50). And for the row, I may be the training data. 

So we have 100 training data/image. And I also have mean from my initial matrix. 

So, now, Im going to plot each data(100) for every feature (50) and also the mean at the same figure. 

Here is the example of figure I want to [plot](http://www.google.fr/imgres?sa=X&espvd=210&es_sm=122&biw=1366&bih=667&tbm=isch&tbnid=qY6rbx4QTw9S_M%3A&imgrefurl=http%3A%2F%2Fwww.aanda.org%2Farticles%2Faa%2Ffull%2F2007%2F07%2Faa6548-06%2Faa6548-06.fig.html&docid=zpg-ZQRMYtuXaM&imgurl=http%3A%2F%2Fwww.aanda.org%2Farticles%2Faa%2Ffull%2F2007%2F07%2Faa6548-06%2Fimg7.gif&w=452&h=422&ei=TGcCU8DmDePe7AbEvoHIAg&zoom=1&iact=rc&dur=1479&page=2&start=17&ndsp=21&ved=0CJABEK0DMBM)..
