Save Template

The appearance settings for various components of a Chart like ChartSeries, ChartArea, Series properties and Point properties can be stored in a template, which can be loaded into new Chart Control when needed.

A chart template can contain the properties of more than one data series. When such templates are loaded into a destination ChartControl, the appearance settings of the data series will be applied in a sequential order, i.e., the first set of appearance settings of a data series will be applied to the destination Chart’s first series and the second set of appearance properties of the data series will be applied to the destination Chart’s second series and so on.

If the destination collection’s length is larger than the source collection, then the settings will repeat itself for these additional entries in the destination collection.

These Charts can be saved as templates in the below two ways.

  • Selecting the Save Template option from the context menu as shown above.
  • By clicking the Save Template designer verb in the Visual Studio property browser as shown above.

ChartTemplate has a static method to save the data programmatically. We need to pass ChartControl instance and a file name(it can accept stream file also.), through this save method.

ChartTemplate.Save(Me.chartControl1, "TemplateName.xml")
