my data analysis in KNIME results in one table which is handed to the report. This table is something like an unpivoted 3D table, that consists of four columns logically being a group id, a row id, a column id and a value. The “length” of each of this axis is variable, so hardcoding was not an option.
My solution for a line plot chart for each group was to nest the line plot in a table with grouping on the grouping column. That worked like a charm.
Now requirements have extended to also supplying a table of values next to the plot. I resorted to using a cross table as described in https://www.knime.com/wiki/generating-reports-with-variable-table-columns.
Sadly the cross table repeats using the data from the first group and does not switch to the according group like the line plot does.
What am I doing wrong or is there a simpler solution to this problem?
