SnapChart.SeriesTemplate Property

Provides access to the template settings for data bound series.

Namespace: DevExpress.Snap.Core.API

Assembly: DevExpress.Snap.v20.1.Core.dll

Declaration

SeriesBase SeriesTemplate { get; }
ReadOnly Property SeriesTemplate As SeriesBase

Property Value

Type Description
SeriesBase

A SeriesBase object that contains template settings for bound series.

Remarks

The SeriesTemplate property provides access to an object that serves as a template for series which are created dynamically as a result of binding a chart to data (using the SnapChart.DataSource and SnapChart.SeriesDataMember properties). Use these template settings to provide centralized customization of all dynamically created data bound series.

Note that the SeriesTemplate settings don't apply to the series contained within the chart's SnapChart.Series collection.
