    Create a Report and Bind Report to Data

    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

    1. In the Report Data Source dialog, select the General page and enter the name of the data source.
    2. Under Type, select 'Json Provider'.
    3. Go to the Content tab under Connection and set the type of JSON data to 'External file or URL'.
    4. In the Select or type the file name or URL field, enter the following URL:
      https://demodata.mescius.io/contoso/odata/v1/FactSales
      For more information, see the JSON Provider topic.
    5. Go to the Connection String tab and verify the generated connection string by clicking the Validate DataSource Validate Icon icon.
    6. Click OK to save the changes and open the DataSet dialog.

    Add a Dataset

    1. In the Dataset dialog, select the General page and enter the name of the dataset, 'FactSales'.
    2. Go to the Query page and enter the following query to fetch the required fields:   
      Query
      Copy Code
      $.value[*]
          
    3. Click OK to save the changes.
    4. Go to the Fields page to view the available fields and modify the Name of the [DateKey] field to [Sales Date].
    5. On the same page, add a calculated field:
      Name Value
      Product Category =Switch([ProductKey] < 116, "Audio", [ProductKey] >= 116 And [ProductKey] < 338, "TV and Video", [ProductKey] >= 338 And [ProductKey] < 944, "Computers", [ProductKey] >= 944 And [ProductKey] < 1316, "Cameras", [ProductKey] >= 1316, "Cell Phones")
    6. 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.

    1. 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.
    2. Select the Query as the dataset name (FactSales) and the Plot Type as 'Area'.
    3. Click Next to configure data values.
      Here, we will define a series value to display the sales amount value along the vertical axis.
    4. Under Configure Chart Data Values,  add a new data value, and set the aggregate and caption, and click Next.                
      Field Aggregate Caption
      [SalesAmount] Sum Sales Amount
    5. In the Configure Chart Data Groupings, set the Categories > Group By to [DateKey].
    6. Set Series > Group By to [Product Category]. Ensure that Series > Layout Type is 'Stack', since we want to subcategorize the sales amount by product categories (i.e. cell phones, computers, cameras, tv and video, and audio) in a stack.
    7. Click Next and Choose Report Colors from Theme and Style, and preview your chart.
