The data points, which uses the **null** or **undefined** as value are considered as empty points. Empty data points are ignored and not plotted in the chart. When the data is provided by using the **Points** property, set the **IsEmpty** to true to specify the particular point is an empty point.

```
<ej-chart id="chartContainer">
// ...
<e-chart-series>
<e-series>
<e-points>
<e-point x="0" y="210"></e-point><e-point x="1" y="0"></e-point>
<e-point x="2" y="150"></e-point><e-point x="3" y="180" is-empty="true"></e-point>
<e-point x="4" y="170"></e-point><e-point x="5" y="200"></e-point>
<e-point x="6" y="140" is-empty="true"></e-point><e-point x="7" y="120"></e-point>
<e-point x="8" y="140"></e-point>
</e-points>
<e-empty-point-settings visible="true"></e-empty-point-settings>
</e-series>
</e-chart-series>
// ...
</ej-chart>
```

## EmptyPointSettings

You can customize the visibility of empty points and change its **DisplayMode** to Gap, Zero, and Average by using **EmptyPointSettings** option.

```
<ej-chart id="chartContainer">
// ...
<e-chart-series>
<e-series>
<e-points>
<e-point x="0" y="210"></e-point><e-point x="1" y="0"></e-point>
<e-point x="2" y="150"></e-point><e-point x="3" y="180" is-empty="true"></e-point>
<e-point x="4" y="170"></e-point><e-point x="5" y="200"></e-point>
<e-point x="6" y="140" is-empty="true"></e-point><e-point x="7" y="120"></e-point>
<e-point x="8" y="140"></e-point>
</e-points>
<e-empty-point-settings visible="true" display-mode="Average"></e-empty-point-settings>
</e-series>
</e-chart-series>
// ...
</ej-chart>
```

If the **Visible** property of EmptyPointSettings is false, then the empty points will be dropped and chart will be rendered without empty points.

## Customizing styles

Empty points color and border can be customized by using **Style** property of EmptyPointSettings.

```
<ej-chart id="chartContainer">
// ...
<e-chart-series>
<e-series>
<e-empty-point-settings visible="true">
<e-Style color="pink"><e-border color="gray" width="2"></e-border></e-Style>
</e-empty-point-settings>
</e-series>
</e-chart-series>
// ...
</ej-chart>
