Hi, I'm trying the "zipmap example" on page http://nodebox.net/node/documentation/using/data-visualization.html, and I can't get right data from zipmap like the sample image:

There's nothing in my lookup node, can anyone help me with the problem? My ndbx file is attached, and I'm using the version 3.0.33 on mac.

Hello,
Put an integer node between the distinct node and the string node. The same thing between the lookup2 and the string node and your problem is solved. It is the decimal point that is causing the problem for the moment. Some users have a problem with it, we are figuring it out. Thanks for bringing it to our attention. -
Adding the two Integer Nodes works! THX for your reply!
