Public API changes

1. Categories of resource

The new resource is a subresource of shape. It works only for Chart shapes and allows to add, modify & delete chart series.

Example 1 (Add category to a chart)

POST https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/categories?folder=myFolder

Request body:

{ "value": "NewCategory", "dataPoints": [{ "value": 5.5 }, { "value": 76 }, { "value": 27 }] }

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
ChartCategory dto = new ChartCategory
{
    Value = "NewCategory",
    DataPoints = new List<OneValueChartDataPoint>
    {
        new OneValueChartDataPoint { Value = 5.5 },
        new OneValueChartDataPoint { Value = 76 },
        new OneValueChartDataPoint { Value = 27 }
    }
};
PostChartCategoryRequest request = new PostChartCategoryRequest
{
    Name = "myPresentaion.pptx",
    Folder = "myFolder",
    SlideIndex = 1,
    ShapeIndex = 1,
    Category = dto
};
Chart chart = api.PostChartCategory(request);
Console.WriteLine(chart.Categories.Count);

Example 2 (Update chart category)

PUT https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/categories/2?folder=myFolder

Request body:

{ "value": "UpdatedCategory", "dataPoints": [{ "value": 5.5 }, { "value": 76 }, { "value": 27 }] }

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
ChartCategory dto = new ChartCategory
{
    Value = "UpdatedCategory",
    DataPoints = new List<OneValueChartDataPoint>
    {
        new OneValueChartDataPoint { Value = 5.5 },
        new OneValueChartDataPoint { Value = 76 },
        new OneValueChartDataPoint { Value = 27 }
    }
};
PutChartCategoryRequest request = new PutChartCategoryRequest
{
    Name = "myPresentaion.pptx",
    Folder = "myFolder",
    SlideIndex = 1,
    ShapeIndex = 1,
    CategoryIndex = 2,
    Category = dto
};
Chart chart = api.PutChartCategory(request);
Console.WriteLine(chart.Categories.Count);

Example 3 (Delete chart category)

DELETE https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/categories/2?folder=myFolder

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
DeleteChartCategoryRequest request = new DeleteChartCategoryRequest
{
    Name = "myPresentaion.pptx",
    Folder = "myFolder",
    SlideIndex = 1,
    ShapeIndex = 1,
    CategoryIndex = 2
};
Chart chart = api.DeleteChartCategory(request);
Console.WriteLine(chart.Categories.Count);

2. dataPoints resource

The new resource is a subresource of series. It works only for Chart shapes and allows us to add, modify & delete individual data points.

Example 1 (Add a data point to a chart series)

This works with scatter & bubble series. You cannot create a data point for a one-value series without creating a relevant category.

POST https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/series/2/dataPoints?folder=myFolder

Request body:

{ "XValue": 5.5, "YValue": 8 }

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
ScatterChartDataPoint dto = new ScatterChartDataPoint
{
 XValue = 5.5,
 YValue = 8
};
PostChartDataPointRequest request = new PostChartDataPointRequest
{
 Name = "myPresentaion.pptx",
 Folder = "myFolder",
 SlideIndex = 1,
 ShapeIndex = 1,
 SeriesIndex = 2,
 DataPoint = dto
};
Chart chart = api.PostChartDataPoint(request);
Console.WriteLine(((ScatterSeries)chart.Series[1]).DataPoints.Count);

Example 2 (Update chart data point)

PUT https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/series/2/dataPoints/2?folder=myFolder

Request body:

{ "XValue": 5.5, "YValue": 8 }

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
ScatterChartDataPoint dto = new ScatterChartDataPoint
{
 XValue = 5.5,
 YValue = 8
};
PutChartDataPointRequest request = new PutChartDataPointRequest
{
 Name = "myPresentaion.pptx",
 Folder = "myFolder",
 SlideIndex = 1,
 ShapeIndex = 1,
 SeriesIndex = 2,
 PointIndex = 2,
 DataPoint = dto
};
Chart chart = api.PutChartDataPoint(request);
Console.WriteLine(((ScatterSeries)chart.Series[1]).DataPoints[1].XValue); //5.5

Example 3 (Delete chart data point)

DELETE https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/slides/1/shapes/1/series/2/dataPoints/2?folder=myFolder

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
DeleteChartDataPointRequest request = new DeleteChartDataPointRequest
{
 Name = "myPresentaion.pptx",
 Folder = "myFolder",
 SlideIndex = 1,
 ShapeIndex = 1,
 SeriesIndex = 2,
 PointIndex = 2
};
Chart chart = api.DeleteChartDataPoint(request);
Console.WriteLine(((ScatterSeries)chart.Series[1]).DataPoints.Count);

3. DefaultRegularFont property

ExportOptions class now has DefaultRegularFont property which allows us to specify the default font to substitute a custom font in case it is not available.

Example

POST https://api.aspose.cloud/v3.0/slides/myPresentaion.pptx/pdf?folder=myFolder

Request body:

{ "DefaultRegularFont": "Calibri" }

SDK Code:

SlidesApi api = new SlidesApi("MyAppSid", "MyAppKey");
PostSlidesSaveAsRequest request = new PostSlidesSaveAsRequest
{
 Name = "myPresentaion.pptx",
 Folder = "myFolder",
 Format = ExportFormat.Pdf,
 Options = new PdfExportOptions { DefaultRegularFont = "Calibri" }
};
Stream response = api.PostSlidesSaveAs(request);
response.CopyTo(File.Create("myPresentation.pdf"));
