when using auto model i got this density plot.
I do not have negative values. How do i remove negative values and what operator is used to plot density plots

If you want to avoid this, you may want to try Kernel Naive Bayes instead.However, if you simply would like to get a distribution curve like yours, the upcoming RapidMiner release will offer a new (and very cool!) new visualization framework where you can easily create such a chart yourself (see below). You can try it yourself already with the public beta version available here: http://static.rapidminer.com/rnd/html/rapidminer9.2preview.htmlHope this helps,
Ingo

Can you share your dataset in order to understand ?

After reflection, I think you have to keep these curves like that (although you have no negative values) : With Naive Bayes, when dealing with continuous data, a typical assumption is that the continuous values associated with each class are distributed according to a Gaussian distribution :
