# Interpolating Nulls in FlexChart

Learn about the options for handling null values using Wijmo's FlexChart in this documentation topic

## Content

The __interpolatingNulls__ property determines whether to interpolate null values in the data. 

If true, the chart interpolates the value of any missing data based on neighboring points. If false, it leaves a break in lines and areas at the points with null values. 

For line and area charts, you can display gaps in the data as empty by setting this property to false.

Example:

```JavaScript
import * as chart from '@mescius/wijmo.chart';
var myChart = new chart.FlexChart('#myChart');
myChart.interpolateNulls = false;
```
