Bar3 function inputs for multiple data plots (detached style)?

Hi everyone, I have the following data and code to represent 3 different data sets as frequency plots using bar3 detached style. I have studied the description of bar3 and tried to plot bar3 but unfortunately couldn't succeed in getting required results. Kindly advise me how should I input the function to get the results in detached style currently I am getting them in stacked style(figure) which is not default for bar3.
