    In This Topic

    This walkthrough creates a Stacked Spiral Chart. The chart shows the sales by product categories for each sales channel. In a stacked spiral chart, the data values are broken down into subcategories and are stacked next to each other. The final chart appears like this:

    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 Data Source 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

      $.value[*]
    3. On the same page, add two calculated fields:
      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")
      Sales Channel =Switch([ChannelKey] = 1, "Store", [ChannelKey] = 2, "Online", [ChannelKey] = 3, "Catalog", [ChannelKey] = 4, "Reseller")
    4. 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 (Stats)  and the Plot Type as 'Spiral'.
    3. Click Next to configure data values.
    4. Under Configure Chart Data Values, add the following value from the drop-down, set the corresponding captions, and click Next.    
      Field Aggregate Caption
      [SalesAmount] Sum Sales Amount
    5. In the Configure Chart Data Groupings, set the Categories > Group By to [Product Category].
    6. Set the Series > Group By to [Sales Channel]. Keep the remaining settings as it is. Ensure that Series > Layout Type is 'Stack'.
    7. Click Next and Choose Report Colors from Theme and Style, and preview your chart.
