title: Fail to understand histogram in WEKA
body: <p>I am new to Weka. I have a dataset. When I try to load the dataset in preprocess phase, I got the following picture</p>
  <p><a href="https://i.stack.imgur.com/IJdBU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IJdBU.png" alt="enter image description here" /></a></p>
  <p>There is a class in my dataset. The dataset predicts cancer. Is it malignant or benign? The blue portion is for malignant and the red portion is for benign.</p>
  <p>I would like to know what is the meaning of this histogram? Here some portion is blue, some is red and some is the mixture of red and blue.</p>
  <p>Also some number like 189,104,128 is associated with the histrogram.</p>
  <p>Can anyone please explain me the graph?</p>
  <p>Thank you.</p>
