Class

ChartBase<TSeries>

Declaration

protected ChartBase()

Sets a unique identifier for the chart component. Use this to associate the chart with related components like TelerikChartBreadcrumb. Essential for drill-down functionality and connecting multiple chart-related components. Must be unique across all chart instances on the same page.

Declaration

[Parameter]
public string Id { get; set; }

Property Value

Fires when users click on axis labels (category or value axis labels). Enable interactive axis behavior for filtering, drilling, or navigation scenarios. Provides access to the clicked label text, axis information, and data context. Commonly used to filter data based on category or implement axis-based navigation.

Declaration

[Parameter]
public EventCallback<ChartAxisLabelClickEventArgs> OnAxisLabelClick { get; set; }

Property Value

Fires when a pan (drag) gesture completes and the chart has settled on new axis ranges. Use to read the updated AxisRanges and reload data for the new visible window or update related components. Only axes with a Name set appear in the dictionary. Requires ChartPannable to be enabled on the chart.

Declaration

[Parameter]
public EventCallback<ChartDragEndEventArgs> OnDragEnd { get; set; }

Property Value

Fires at the start of a pan (drag) gesture. Use to capture the axis ranges before the user moves the visible window. The event args expose an AxisRanges dictionary keyed by axis name — only axes with a Name set are included. Panning is only active when the chart is already zoomed in. Requires ChartPannable to be enabled on the chart.

Declaration

[Parameter]
public EventCallback<ChartDragStartEventArgs> OnDragStart { get; set; }

Property Value

Fires when users click on legend items to toggle series visibility or perform custom actions. Enable legend-based chart interaction for showing/hiding data series. Provides access to the legend item details and associated series information. Use this to implement custom legend behavior beyond the default visibility toggle.

Declaration

[Parameter]
public EventCallback<ChartLegendItemClickEventArgs> OnLegendItemClick { get; set; }

Property Value

Fires when users click on any data point, column, line, or chart element in the series. Enable interactive behavior for chart data exploration and selection. Provides access to the clicked data item, series information, and chart coordinates. Commonly used for navigation, showing details, or updating related components.

Declaration

[Parameter]
public EventCallback<ChartSeriesClickEventArgs> OnSeriesClick { get; set; }

Property Value

Fires when a zoom gesture completes and the chart has settled on new axis ranges. Use to read the updated AxisRanges and synchronize external state, reload data for the visible window, or persist the zoom level. Only axes with a Name set appear in the dictionary. Requires ChartZoomable to be enabled on the chart.

Declaration

[Parameter]
public EventCallback<ChartZoomEndEventArgs> OnZoomEnd { get; set; }

Property Value

Fires at the start of a zoom gesture (mousewheel, pinch, or selection box). Use to capture the axis ranges before any zoom is applied. The event args expose an AxisRanges dictionary keyed by axis name — only axes with a Name set are included. Requires ChartZoomable to be enabled on the chart.
