How to plot using svmtoy libsvm matlab?

08 August 2014 1 2K Report

What is the file format it accepts for svmtoy and how to display a proper svm plot with data points. I made .txt files in libsvm file syntax i.e. label index:value... but don't get datapoints in output screen.Can anyone help please?

Gavin Rhys Lloyd

If your file syntax is definitely correct then try making sure that all data points have values between 0 and 1 as I think the plot for svmtoy is limited to this range.
