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);
    }
