 If your server stores data in JSON format, you do not need to make AJAX requests to get the data.

To configure how the component displays data, specify the [series](Documentation/ApiReference/UI_Components/dxChart/Configuration/series/) type and its nested options: [argumentField](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/#argumentField) and [valueField](/Documentation/ApiReference/UI_Components/dxChart/Configuration/series/#valueField), so the component can determine the object fields that indicate Chart arguments and values in JSON.

 This demo illustrates a common issue in multi-series charts. Individual [series](/Documentation/ApiReference/UI_Components/dxChart/Series_Types/BarSeries/) can skip values for certain arguments or include zero values. In such cases, arguments can display a different number of bars and cause uneven gaps between data.

 The [ignoreEmptyPoints](/Documentation/ApiReference/UI_Components/dxChart/Series_Types/BarSeries/#ignoreEmptyPoints) property allows you to change this behavior. If you set it to **true**, bars increase their width to fill the gaps. In this demo, you can see how the property affects the following arguments: `Iran`, `Canada`, `Saudi Arabia`, and `Mexico`.

 The Chart component initially displays axes along pane borders. Several other predefined axis layout properties are available. In this demo, the [customPosition](/Documentation/ApiReference/UI_Components/dxChart/Configuration/argumentAxis/#customPosition) property is used to move each axis, so that it is displayed on the specified value of another axis. When you position the [argument axis](/Documentation/ApiReference/UI_Components/dxChart/Configuration/argumentAxis/), use values from the [value axis](/Documentation/ApiReference/UI_Components/dxChart/Configuration/valueAxis/) (in the same type and format) and vice versa.

 Regardless of which automatic axis layout type you use, the Chart Control allows you to apply manual offsets.
