Violin Plot - Compare Data

Contrasting and comparing are part of data analysis to make vital decisions. A violin chart integrated with Box Plot is one of the charts that can be used to compare data. Let us see how we can utilize the Orange data mining tool to compare data using the Violin chart. 

Let us assume that the following is the dataset that we need to compare. 

In this dataset, there are five variables to compare. If you simply use a Violin chart without any preprocessing, you cannot compare charts in one chart. Therefore, there are a few preprocessing tasks to be done.

In the above preprocessing tasks, separate processing tasks are used for each variable. Select Columns, Edit Domain, and Feature Constructor are used. You can download the Orange workflow at ODM/Violine-Blog.ows at main · dineshasanka/ODM (github.com) 

Finally, all data flows are connected and then used to Violin Plot, as shown below.

Now you can see from the above chart, it is easily can be compared. In the above example, X1 has higher values.
