Hello guys! I have Data Mining class and in order to prepare my report I have to know more about histograms.
I have a file, which I attach this thread, showing a log which belongs to a phone company. The last column ("churn") indicates that if the user resigned from the operator or not. My mission is to find interesting relationships showing why user have resigned from the operator. For example, I choose one of the columns (e.g Day Mins) and examine it. If people who has lots of day mins tend to resign, I have to prove this.
I want to plot an histogram for indicating that. I have the information of who has resigned or not as true or false values. So how can I split each bar into two bars. A single bar will contain two bars. One bar at the down is people who have resigned and the other bar at the top will be the people who did not resign. In attachment I also giving you the plot that I made.
