Can convert portal report into sail report and display in a char?

Hi Eagle,
You can convert portal into SAIL report by using the out of the box function (a!queryProcessAnalytics) and you can display any type of charts in it.
Here is the link for your reference.

Yes you can convert the same in two ways. Using Appian Functions

If you are using 7.8 and above you can use the function (a!queryProcessAnalytics)
If you are using below 7.8 you can use the function (getportalreportdatasubset)

Using the report id this will convert into datasubset and you can use it whereever you need it in you sail Reports.

one question, if the portal report is a barchart with grouping and aggregation, can it be transformed to sail report with same display?

@shaoyongw The answer to your question first depends on the version. So here goes the answer to your question from the perspective of Appian version:
1. Appian 7.7 and below: You could use Portal to SAIL plugin(Please find attached the document). There is a function by name executePortalReportForSail and I guess it gets the job done directly without any further work. But if you aren't happy with this function, I believe that the only way is to apply the SAIL design over the resultant datasubset obtained from fn!getportalreportdatasubset().
2. Appian 7.8 and above: I believe there isn't a direct way of doing so (like executePortalReportForSail in Portal to SAIL plugin as discussed above). We should apply the SAIL design over the resultant datasubset obtained from a!queryProcessAnalytics().
