title: Creating a boxplot from two tables in KNIME
body: <p>I am trying to plot two data columns coming from different tables using KNIME. I want to plot them in a single plot in order to be easier to compare them. In R this effect can be achieved by the following:</p>
  
  <pre><code>boxplot(df$Delay, df2$Delay,names=c("Column from Table1","Column from Table2"), outline=FALSE)
  </code></pre>
  
  <p>However, by using KNIME, I cannot think of a way that you can use data coming from two different tables. Have you ever faced this issue in KNIME?</p>
