# Data provider properties

The **Data Provider properties** in the **Data Series Wizard** define **how the data series connects to an external data source**, ensuring your chart is populated with **real-time data**.

***

## **Properties Overview**

| **Property**                | **Description**                                                                                                                                                    |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Select Data Provider**    | Choose an existing **data provider** (table, query, stored procedure, XML file, RSS feed, etc.) that feeds the data series.                                        |
|                             | Data providers are defined **at the presentation level** and are available to all elements. You can create a **new provider on-the-fly** via the drop-down button. |
| **Data Column**             | Select the **column** from the data provider that contains the **main data values** for the chart.                                                                 |
| **Label Column** (Optional) | Select a **column** that contains **labels** associated with the data values (e.g., product names, dates).                                                         |

## **Key Notes**

* **Data Providers** allow dynamic, real-time data feeding for live updates in your charts.
* Column selection **binds specific fields** from your source data to the chart for visualization.
* Different chart types (e.g., Bubble, Stock) require **specialized columns** to represent data properly.
* You can define **new data providers directly** while setting up your data series for convenience.
