Thanks for your response Steve.\n\nI was trying to understand what are the treemap data assumptions.\n\nLooks like its assuming a table/resultset structure.\n\nMy resultset has really simple stuff going on.\nAll numeric columns:\nRecency, Count of people, no.of.rides\n\nI would've expected it to ask, what variable do you want to base colour on, what variable for size etc. In the absence of that, and no hint from the error, I'm still struggling to see what can be the "incompatible" value.
