Hi, I am attempting to use data gathered by a python script to create a chart with zgdchart. I am using zope 2.6.4, zgdchart 0.6.4 on windows 2000. Within a zgdchart object, if I use a dtml method as the data method with code such as: <dtml-return "(('syd','melb','bris', 'adel', 'perth'),(5, 7, 6, 4, 6),(5, 10, 5, 1, 6))"> the chart works fine. When I try to use a python script as the data method, with code such as: return (('syd','melb','bris', 'adel', 'perth'),(5, 7, 6, 4, 6),(5, 10, 5, 1, 6)) the chart fails to be produced. Can anyone provide any tips? Thanks, Josh
