Hello everyone! I would like to know if there is a node in Dynamo that can act like UI.Messenger, a UI window pops up in the Revit interface to display information, except for the UI.Messenger displays text information, but this node can integrate the information into a pie chart.
The Pie chart node displays a pie chart in the Dynamo interface, but I need to display it in the Revit interface
Maybe Datashapes will do what you need?

Thank you for your reply. But what I need is a node for outputting results, not an input node
all right…I found that Datashape can complete my task. Thank you for your reminder!
The pie chart created using Datashape is not very aesthetically pleasing. Can UI nodes achieve the same effect as above?
The python code in datashapes can be unwrapped and edited, if you want to dive into how they work you could use it as a platform to work from to get exactly what you want, just make sure you credit the original author in your code 
Others may know of some other methods to achive this as well
I got it. thank you 
Hi,

be careful, there are some changes with dynamo 3 (the LiveCharts library has changed a little)
