SVM results plot modification

Hi, I am using SVM for classification and i need output plot similar to this:

but in 2D. I did use this http://stackoverflow.com/questions/16146212/how-to-plot-a-hyper-plane-in-3d-for-the-svm-results and made a little updates. Usual ShowPlot command isn't enough for me, because I need to see properly and improperly classified samples to proof specificity and sensitivity of classification.

My main concern is how do i obtain division line properties from SVMstruct or how do i clear out training groups from plot.

Thank you.
