Hi, First sorry for my awful english. I have a problem with bar chart and nominal values. The problem is that I want to see more than a single bar chart in a single image produced from the bar chart node with nominal values. I’ll show you an example: |BOY OR GIRL| |DO YOU LIKE SCHOOL| boy - yes a lot boy - yes girl - yes a lot boy - not a lot girl - yes This is a simple example as I can’t share the real dataset. The question is how I can made a bar chart that contain this two categories which they have nominal values inside? I see that works with integers, as I could choose more than a column and plot them. The problem is that the menu option show me only one category from the column category which contain nominal values [S] while I want more than one column, in the previously example I want to plot both the column for example. I also tried to convert a columns [S] into a column [I] and then plot the result, but the console show me this message: “Values in 29 cells could not be parsed, first error: ‘Girl’ (RowKey: Row0, Position: 8)”, and I don’t know how to solve it Thanks for the help.

Is this what you are trying for?

In KNIME bar chat node takes only one. [grouped-column-chart-reference-small] Or a single stacked bar per category?
