Methods

SfChart contains the following overloading methods for saving a chart as an image.

Save()

This method will export the chart as image into a desired location by using FileSavePicker.

C#

private void SaveImageButton_Click(object sender, RoutedEventArgs e)
{
    this.SampleChart.Save();
}

Save(string fileName, StorageFolder folderLocation)

This method will export the chart as image to the specified location. The following code example illustrates the usage of this method.

C#

private void SaveImageLocation_Click(object sender, RoutedEventArgs e)
{
    StorageFolder storageFolder = Windows.Storage.KnownFolders.PicturesLibrary;
    this.SampleChart.Save("ChartImage", storageFolder);
}

If you did not specify any location, the image will be saved to the corresponding application’s bin\x86\Debug\AppX

C#

Chart.Save("Chart", null);

Save(IRandomAccessStream stream, Guid bitmapEncoderID)

This method allows you to export the chart into a stream. It is described in following code example.

C#

private async void SaveImageEncoder_Click(object sender, RoutedEventArgs e)
{
    StorageFile storageFile = await Windows.Storage.KnownFolders.PicturesLibrary.CreateFileAsync("EncodedChartImage");
    Guid encoder = BitmapEncoder.BmpEncoderId;
    this.SampleChart.Save(await storageFile.OpenAsync(FileAccessMode.ReadWrite), encoder);
}
