Create a Report

In the ActiveReports Designer, create a new RDLX report and follow the New Report wizard to bind the report to data. You can also perform data binding later using the Report Data Source dialog accessed from the Report Explorer.

Connect to a Data Source

In the Report Data Source dialog, select the General page and enter the name of the data source.
Under Type, select 'Json Provider'.
Go to the Content tab under Connection and set the type of JSON data to 'Embedded'.

In the Select or type the file name or URL or enter the data to be embedded field, enter the following data:

For more information, see the JSON Provider topic.

Go to the Connection String tab and verify the generated connection string by clicking the Validate DataSource
icon.
Click OK to save the changes and open the DataSet dialog.

Add a Dataset

In the Dataset dialog, select the General page and enter the name of the dataset, 'Measurements'.
Go to the Query page and enter the following query to fetch the required fields:
```
$.[*]
```
Click OK to save the changes.

Create Basic Structure of Chart

We will use the Chart Wizard dialog to configure chart data values and basic customization. If you have a dataset added to your report, on Chart's drag-drop operation, the wizard appears. See the topic on Chart Wizard for more information. You can make further adjustments to the chart after you exit the wizard by accessing the properties of chart elements through dialogs, property panels, and adorners.

Drag-drop Chart data region onto the design area. The New Chart dialog appears with an option to select the query and the plot type.
Select the Query as the dataset name (Measurements) and the Plot Type as 'Bubble'.
Click Next to configure data values. We will define three data values to show the 'Girth', 'Height', and 'Volume' of the trees.
Under Configure Chart Data Values, add the following two values from the drop-down, set the corresponding aggregates and captions, and click Next.

Field Caption

[Girth] X

[Height] Y

[Volume] Size
Skip the Configure Chart Data Groupings.
Click Next and Choose Report Colors from Theme and Style, and preview your chart.

Now that the basic structure of your chart is ready, let us add more meaning to the chart using the properties via the Chart Panels, Adorners, and Property Panel.

Field	Caption
[Girth]	X
[Height]	Y
[Volume]	Size
