Serialization

SciChart supports serialization of the chart settings to XML. This is useful if you wish to persist a chart configuration and restore it.

Serialization of Chart Settings

To serialize a chart, use the following code. This code will serialize a SciChartSurface and its settings to MemoryStream but you can use any other stream e.g. FileStream to save XML to a file.

Serialization of Chart Settings
Copy Code
var stream = new MemoryStream();
var serializer = new XmlSerializer(typeof(SciChartSurface));
serializer.Serialize(stream, SciChartSurface);

Deserialization of Chart Settings

To restore a chart from XML use the following code:

Deserialization of Chart Settings
Copy Code
String xmlString = … // assuming you have the XML string in memory
var stream = new MemoryStream(Encoding.ASCII.GetBytes(xmlString));
var serializer = new XmlSerializer(typeof(SciChartSurface));
stream.Position = 0;
var chart = (SciChartSurface)serializer.Deserialize(stream);
chart.RenderableSeries.First().DataSeries = DataSeries;

Serialization of Chart Data

Currently SciChart does not support serialization of chart data out of the box, however, if you see Accessing X,Y Values (read-only)  , you can access the DataSeries.XValues and DataSeries.YValues as a list and persist these as you wish.

Example of Serialization Output

An example of serialization output is included below.

Serializing and Deserializing Across SciChart Versions

You will notice many types are qualified by their fully-qualified assembly name. This is unfortunately unavoidable as serialization across assemblies requires that the fully-qualified name is included in the serialized output.

What we suggest if you need to serialize and deserialize across version(s) is to pre-process the fully XML string and replace the fully qualified assembly names.

For instance:

Find: SciChart.Charting.Model.AxisCollection, SciChart.Charting,
                 Version=4.0.0.5900, Culture=neutral, PublicKeyToken=b55dd9efe817e823

Replace: SciChart.Charting.Model.AxisCollection, SciChart.Charting,
                 Version=4.0.1.6200, Culture=neutral, PublicKeyToken=b55dd9efe817e823

 

This will upgrade the XML to be compatible to a newer version of SciChart.
