-If your data contains an error or measurement uncertainty, you can indicate a confidential interval on the Chart using error bars. To configure them, use the fields of the series’ **valueErrorBar** object. In this example, error bars indicate a range of average temperatures (on the upper pane) and humidity (on the lower pane) for a specific month.

+DevExtreme Chart supports value error bars. Implement these bars to indicate data measurement tolerances and [confidence intervals](https://en.wikipedia.org/wiki/Confidence_interval). Configure error bar settings and appearance in the **series**.[valueErrorBar](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/valueErrorBar/) object.

+To enable error bars, specify one of the following pairs of **valueErrorBar** properties:
+
+- [lowValueField](Documentation/ApiReference/UI_Components/dxChart/Configuration/series/valueErrorBar/#lowValueField) and [highValueField](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/valueErrorBar/#highValueField)    
+Specify predefined error bars for each series point.

+- [value](Documentation/ApiReference/UI_Components/dxChart/Configuration/series/valueErrorBar/#value) and [type](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/valueErrorBar/#type)    
+Configure dynamically calculated error bars.

+This demo implements predefined error bars specified in the Chart data source.

+The DevExtreme Chart component allows you to display data in multiple panes.

-In this demo, the DevExtreme Chart component is used to create a [Pareto chart][0]. This example of a Pareto chart summarizes complaints about the service provided by a pizza shop. From this chart, the pizza shop owner may infer that to satisfy most of the customers, he or she needs to eliminate two most frequently encountered issues: delayed delivery and cold pizza.
+You can utilize the DevExtreme Chart component to display data in a [Pareto chart](https://en.wikipedia.org/wiki/Pareto_chart). A Pareto chart displays individual values along with their cumulative totals. In this demo, individual values are numbers of complaints and cumulative totals are represented as percentages.
