Hi, sorry for my english, I need to to do a bar chart with this data-set.
My idea is to plot four bar graphics in one single image, where the first plot represent the first categories and the frequency of the answers, and same graphics for the second, the third and the fourth categories.
Thanks for the help
Hello @violandre01
Could you provide some data? so Itâll be easier for others in the forum to help. In the picture we cannot even see the column headers; âview >> wrap column headerâ in table options is great for that.
Meanwhile, you can download and explore the solution to #justknimeit-8 , you may find similarities to your challenge:
You may consider to work with the âHistogramâ nodes as well, as they can perform the counting on string items.

Hi @violandre01
Please have a look to this workflow, these are just the basics.

In the current chart you can deselect the questions by clicking on the colored legend. Otherwise I aggregated a column filter for sending only the question that you want to displayâŚ
Some more automatization can be done to be incorporated within a âComponentâ, but we donât know about your use case.

Thanks for the help.
Do you think itâs also possible invert the graphic? For example in the x-label the questions, and in the y-label the frequency of an answer? I ask you this as the questions are cathegories and I donât know if KNIME allow this.

You can flip the axis and make it horizontal as well in âGeneral Plot Options >> Plot horizontal bar chartâ
