# Using an Unbound Data Source

This topic explains how you can create charts using unbound data. Learn more in documentation.

## Content

You can add double values to the Chart control without using a data source.

## Using Code

Use the [Values](/spreadnet/api/latest/online-asp/FarPoint.Web.Chart/FarPoint.Web.Chart.BarSeries.Values.html) property of the series to add data.

## Example

The following example demonstrates adding unbound data to the control.

```csharp
BarSeries series = new BarSeries();
series.Values.Add(2.0);
series.Values.Add(4.0);
series.Values.Add(3.0);
series.Values.Add(5.0);
```

```vbnet
Dim series As New BarSeries()
series.Values.Add(2.0)
series.Values.Add(4.0)
series.Values.Add(3.0)
series.Values.Add(5.0)
```
