I would like to use a trace attribute of my choice for trace colouring in the Inductive Visual Miner. However, when opening the trace colouring dialogue in the IvM, I only get the options "concept:name", "duration" and "number of events".
My eventlog contains plenty of variables at the trace level, but they're not shown in the trace colouring dialogue of the IvM. I suspect that I should define this in the plugin "Convert CSV to XES", which I use as a first step. I have tried the "Show Expert Configuration" dialogue when converting my CSV to XES to define trace attributes, but to no avail. Whatever I assign to the cells in the row "XES Extension" gets ignored later by the trace colouring dialogue box of the IvM.
How can I tell ProM that a specific attribute xy should be treated as a trace-level attribute, so that it's included in the trace colouring dialogue of the IvM? In which plugin and how specifically?
