| 36 | You can represent scatter data by creating a ScatterSeries inside |
|---|
| 37 | GraphsView. The data can be added to the graph by creating XYPoints as |
|---|
| 38 | children for the ScatterSeries that define the x and y values of each |
|---|
| 39 | point. |

| 59 | \endcode |
|---|
| 60 | |
|---|
| 61 | Multiple scatter graphs can be created by adding multiple ScatterSeries |
|---|
| 62 | as children of GraphsView. In such cases only one series should define |
|---|
| 63 | the axis used as multiple definitions only override the earlier ones. |
