Creating a pareto chart in RapidMiner

Question

I am not able to plot a simple pareto chart.

My data looks like:

and when I try to create a pareto chart, I get a blank space, I also cannot select a value for "Count Value":

What am I missing here? My sample data is stored in that xml:

Answer 1

So I found a workaround (thanks to Andrew), which is only working for this example set.

I had to "de-aggregate" it and add a new polynominal attribute with the same value for every example.

Then I could create a Pareto chart, group-by 'category' and set the count-column to the new attribute.

Lead to this chart:

When I do this with my dataset I get this chart:

I guess without being able to configure the pareto chart, it is really bad for a lot of different values in the group-by category.
