This issue was solved for the specific article scenario.
If I have a property which is a dataset, returned by a web-service invoke, when I set -dataobject to the property I dont get anything displayed. Can you confirm it, please.
I do something like:
InvokeService.ps1 | out-chart -dataobject Dataset .......
In InvokeService.ps1 I prepare the object as stated in the article.
Thanks,
Cosmin
