[Calculated field in domain]

To add a table-based calculate field while creating a new domain, right-click the table and select Create Calculated field. This should show the fields that are in the table.

I am using JRS 8.0 as well.  Using this wiki for 6.4 I get to a different dialog than what you have displayed. Not sure where you are creating the field. I am creating an ad hoc view and creating/adding a calculated field.  https://community.jaspersoft.com/documentation/tibco-jasperreports-server-user-guide/v640/creating-calculated-field

[Where is the HTML Component?]

I am using Jaspersoft Studio Professional 7.9.0 - Visual Designer for JasperReports 6.16.0 and looking in the palette for the component.  Also where can I find documentation on usage?

[Box Plot Chart Type]

I am interested in using a box plot chart.  A user asked about this in an earlier post.  I am in Jaspersoft Studio v 7.9 and I don't see it in HTML5 charts.  Please indicate how I can use this type chart.
