Pie chart doesn't work if category is null and it doesn't throw any exception either. I'm using Pentaho 3.10 and CDE 1.0RC3
Hi, Have you tried updating your Ctools installation?
You can do that by using the ctools-installer. Further info here:
1.0RC3 is an old, outdated version. We're implementing a steady release flow to avoid having outdated versions in our site but it's still work in progress
