[Moose-dev] Question about DistributionMaps

Hi folks. I am trying to script some distribution maps. For the moment I was doing simple things with just two colors. Example: ^ (DistributionMap onContainers: (self listOfCorePackages collect: [ :each | (PackageInfo named: each) ]) elements: #classes properties: [:element | element hasUsedInstances = true] ) render open. That show me classes with used instances with blue and the rest with red. Now I want: element hasUsedInstances = true -> blue element instanceCount > 0 and: [hasUsedInstances = false] -> red the rest (without instances) -> yellow Forget about the colors, I don't care which color (although it would be cool to be able to choose). What I don't know how to do is to define multiple properties. And I cannot use the wizard, I have to do it by code ;) Can someone help ? Thank you very much in advance. Mariano
