-In many cases, you need to process data on the server before a chart displays it. The Chart component supports this scenario. 
-
-In this demo, the data source of the Chart loads weather data for a selected month from an OData service. Each time you select a different month in the drop-down menu, the data source sends a new query to the service. To implement this functionality, assign a [DataSource](/Documentation/ApiReference/Data_Layer/DataSource/) object to the Chart's [dataSource](/Documentation/ApiReference/UI_Components/dxChart/Configuration/#dataSource) property. 
+DevExtreme Chart supports remote data processing. In this demo, the component loads weather data for the specified month from an ASP.NET backend service. When you change the month value via the dropdown, our Chart component sends a new query to update displayed data.

-In the [DataSource](/Documentation/ApiReference/Data_Layer/DataSource/), implement the [ODataStore](/Documentation/ApiReference/Data_Layer/ODataStore/). An OData service can include multiple entity collections related to each other, but the [ODataStore](/Documentation/ApiReference/Data_Layer/ODataStore/) specifies only one collection. To load multiple collections at once, set the [expand](/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#expand) property to an array with the additional collection titles. Then, call the [postProcess](/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#postProcess) function to process additional data.
-
-Set the [paginate](/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#paginate) property to **false** to prevent data from partitioning. You can also apply a [filter](/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#filter) to the received values.
+To bind data from a remote source, this demo implements a [CustomStore](/Documentation/ApiReference/Data_Layer/CustomStore/) (within a [DataSource](/Documentation/ApiReference/Data_Layer/DataSource/) object) and fetches data using the [load](/Documentation/ApiReference/Data_Layer/CustomStore/Configuration/#load) method. To process data on the server, the ASP.NET backend service is configured to accept processing operations in each request. For backend implementation details, refer to **TemperatureDataController.cs** in the ASP.NET Core version of this demo: [Server-Side Data Processing - ASP.NET Core Charts](https://demos.devexpress.com/AspNetCore/Demo/Charts/ServerSideDataProcessing).
 
-Once you load the data, specify the [series](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/) type and its nested options ([argumentField](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/#argumentField) and [valueField](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/#valueField)), so the component can determine the objects that indicate Chart arguments and values in the data source.
+You can shape data within the **DataSource** as needed (for instance, apply a [filter](/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#filter)). Disable the [paginate](/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#paginate) property to prevent data partitioning.
 
 ### A 1-Click Solution for CRUD Web API Services with Role-based Access Control via EF Core
 
-If you target .NET for your backend API, be sure to check out [Web API Service](https://docs.devexpress.com/eXpressAppFramework/403394/backend-web-api-service?utm_source=js.devexpress.com&utm_medium=referral&utm_campaign=xaf&utm_content=data-layer-odatastore) and register your [free copy today](https://www.devexpress.com/security-api-free?utm_source=js.devexpress.com&utm_medium=referral&utm_campaign=xaf&utm_content=data-layer-odatastore). The Solution Wizard scaffolds an OData v4 Web API Service (.NET 6+) with integrated authorization & CRUD operations powered by EF Core ORM. You can use OAuth2, JWT or custom authentication strategies alongside tools like Postman or Swagger (OpenAPI) for API testing.

The Template Kit scaffolds an OData v4 Web API Service (.NET 8+) with integrated authorization & CRUD operations powered by EF Core ORM. You can use OAuth2, JWT or custom authentication strategies alongside tools like Postman or Swagger (OpenAPI) for API testing.
 The built-in Web API Service also filters out secured server data based on permissions granted to users. Advanced/enterprise functions include audit trail, endpoints to download reports, file attachments, check validation, obtain localized captions, etc.
