Note that the Key field below the chart updates to show the same value as the series. You create a new subdataset using the Dataset wizard. Subdatasets can have parameters of their own, and if you want to use a report parameter in a subdataset query you would declare the same parameter in the subdataset, and transfer the value to the subdataset via elements. When the result is null or Boolean.FALSE, the current row will be skipped and the datasource will be asked for the next row. How? A dataset describes the shape of the data that is supplied to a report or element for example, the list of fields and field types to use but does not contain any information about where the data will come from. A dataset is a concept that lies somewhere between a data source and a subreport. This tab allows you to set values for the subdataset parameters using calculated expressions. Here's something I'd like to achieve in the result table: Let me start with saying that json structure that you have in question is not the best structure to dynamically handle your expected output, it would have been better if parameter1 was actually inside the second node, see this How to create multiple tables in jasper report using json as a datasource? Subdatasets can be used to iterate through data that is not the main report data source itself, for example, to gather data for a chart or perform data bucketing for a crosstab. Unlike other elements, a table always requires a subdataset; it cannot use the main dataset. The Dataset page of the Dataset wizard shows the following options: A dataset is called empty when it does not have metadata.

To open the Dataset wizard, right-click your report's root node in outline view and select Add Dataset from the context menu. When you define a variable that hosts or collects subdataset return values, you should set its calculation time to System to prevent the values from being recalculated at each iteration of the main dataset. The java bean data source is supplied by a report scriptlet. The dataset run binds the dataset used by the element with a data source and supplies the values for the dataset parameters. Subdataset You can use a subdataset to provide a secondary record nested within a report. The dataset properties are shown in Properties view. A value from the subdataset run is available only after the whole band containing the subdataset has been printed. To set the value that this parameter will have at runtime, define an expression in the dataset run of the element that will use the parameter. Does the policy change for AI-generated content affect users who (want to) Is there a legal reason that organizations often refuse to comment on an issue citing "ongoing litigation"?
