Public API Changes
Support of external workbooks as a data source for charts has been added.
Since version 19.4 Aspose.Slides supports external workbooks as a data source for charts.
IResourceLoadingCallback can be used to manage external workbook loading.
- Chart data in external workbooks can be edited the same way it works for internal workbooks. If external workbook can’t be loaded an exception is thrown.
using (Presentation pres = new Presentation("presentation.pptx"))
{
IChart chart = pres.Slides[0].Shapes[0] as IChart;
ChartData chartData = (ChartData)chart.ChartData;
Assert.AreEqual(chartData.DataSourceType, ChartDataSourceType.ExternalWorkbook);
chartData.Series[0].DataPoints[0].Value.AsCell.Value = 100;
pres.Save(outPptxFileName, SaveFormat.Pptx);
}
- An external workbook can be assigned to a chart as a data source. For this purpose IChartData.SetExternalWorkbook(string workbookPath) method has been added.
SetExternalWorkbook() method can be also used to update a path to the external workbook if it has been moved. *Workbooks placed on remote resources unavailable for data editing but still can be assigned as an external data source. *If the relative path was provided for an external workbook, it converts to full path automatically.
using (Presentation pres = new Presentation())
{
IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Pie, 50, 50, 400, 600, false);
IChartData chartData = chart.ChartData;
Assert.AreEqual(chartData.DataSourceType, ChartDataSourceType.InternalWorkbook);
chartData.SetExternalWorkbook("externalWorkbook.xlsx");
Assert.AreEqual(chartData.DataSourceType, ChartDataSourceType.ExternalWorkbook);
chartData.Series.Add(chartData.ChartDataWorkbook.GetCell(0, "B1"), ChartType.Pie);
chartData.Series[0].DataPoints.AddDataPointForPieSeries(chartData.ChartDataWorkbook.GetCell(0, "B2"));
chartData.Series[0].DataPoints.AddDataPointForPieSeries(chartData.ChartDataWorkbook.GetCell(0, "B3"));
chartData.Series[0].DataPoints.AddDataPointForPieSeries(chartData.ChartDataWorkbook.GetCell(0, "B4"));
chartData.Categories.Add(chartData.ChartDataWorkbook.GetCell(0, "A2"));
chartData.Categories.Add(chartData.ChartDataWorkbook.GetCell(0, "A3"));
chartData.Categories.Add(chartData.ChartDataWorkbook.GetCell(0, "A4"));
pres.Save("Presentation.pptx", SaveFormat.Pptx);
}
- Combination of methods IChartData.ReadWorkbookStream() and IChartData.SetExternalWorkbook() can be used to create an external workbook from scratch or to make an internal workbook external.
using (Presentation pres = new Presentation("presentaion.pptx"))
{
string externalWbPath = "externalWorkbook.pptx";
IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Pie, 50, 50, 400, 600);
if (File.Exists(externalWbPath))
File.Delete(externalWbPath);
using (FileStream fileStream = new FileStream(externalWbPath, FileMode.CreateNew))
{
byte[] worbookData = chart.ChartData.ReadWorkbookStream().ToArray();
fileStream.Write(worbookData, 0, worbookData.Length);
}
chart.ChartData.SetExternalWorkbook(externalWbPath);
}
