Basic question: x axis of a graph

I am a very beginner (today) user of KNime. I am begining with a simple task: analyse some data experiments: scatter plots (done OK) , repartition of values etc…
For the values repartition, I created my own bins and did the sums. I have now a file with 2 columns, 1 represents my “bin” the second “tot” the number of elements in that bin.
I wanted to plot a graph with “bin” as x axis, “tot” as y axis, and with bars, so it looks like an histogram. I can do that with gnuplot 'plot “my.file” using 1:2 with boxes’
I am at lost on how to do it. Is it possible ? Thanks for any help

It’s not what Interactive Histogram node does?
