Step 1. Create a Chart
Create or open a Windows Forms Application.
Drop the ChartControl onto the form from the DX.24.2: Data & Analytics toolbox tab.
When you add the Chart Control to the form, the Chart Designer is shown. We do not need to use this designer, so click the Cancel button to close it.

Click Run Query Builder on the next form:
Use Query Builder to construct SQL queries. Drag the Products table to the work area and select the ProductID, ProductName, CategoryID, and UnitPrice fields. Click the Filter button to launch the Filter Editor.

The newly created SQL query is displayed on the next form. Click Finish.

Click Add… in the Series Collection Editor. Select the Bar view and click OK.
Switch to the Properties tab and set ArgumentDataMember to ProductName.
