How to balance data?

Hello, 
I'm building a decision tree model and the performance is not very well since the data is unbalanced. I tried "sample" function as I've seen in tutorial but there's no option to balance data in it.
can anybody help!

    Hi!

    "balance data" is an "expert parameter" in the Sample operator. Maybe that's why you don't see it?

    Click "Show advanced parameters" at the bottom of the Parameters panel to uncover this setting.
