Public API Changes

IChart.ShowDataLabelsOverMaximum property has been implemented

IChart.ShowDataLabelsOverMaximum and Chart.ShowDataLabelsOverMaximum property has been implemented.

The property specifies whether to show the data labels when the value is greater than the maximum value on the value axis.

{
    System::SharedPtr<Presentation> presentation = System::MakeObject<Presentation>();
    System::Details::DisposeGuard<1> __dispose_guard_0({ presentation});
    try
    {
        System::SharedPtr<ISlide> slide = presentation->get_Slides()->idx_get(0);
        System::SharedPtr<IChart> chart = slide->get_Shapes()->AddChart(Aspose::Slides::Charts::ChartType::ScatterWithMarkers, 20, 100, 600, 400);
        chart->get_ChartData()->get_Series()->idx_get(0)->get_Labels()->get_DefaultDataLabelFormat()->set_ShowValue(true);
        chart->set_ShowDataLabelsOverMaximum(false);
        presentation->Save(u"output.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
    }
    catch(...)
    {
        __dispose_guard_0.SetCurrentException(std::current_exception());
    }
}

IChartSeries.BubbleSizeScale and IChartSeriesGroup.BubbleSizeScale properties have been implemented

IChartSeries.BubbleSizeScale and ChartSeries.BubbleSizeScale properties have been implemented.

Specifies the scale factor for the bubble chart (can be between 0 and 300 percents of the default size). This is the property not only of this series but of all series of parent series group - this is projection of appropriate group property. And so this property is read-only. Use ParentSeriesGroup property for access to parent series group. Use ParentSeriesGroup.BubbleSizeScale read/write property for change value.

IChartSeriesGroup.BubbleSizeScale and IChartSeriesGroup.BubbleSizeScale properties have been implemented.

{
    System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
    System::Details::DisposeGuard<1> __dispose_guard_0({ pres});
    try
    {
        System::SharedPtr<IChart> chart = pres->get_Slides()->idx_get(0)->get_Shapes()->AddChart(Aspose::Slides::Charts::ChartType::Bubble, 100, 100, 400, 300);
        chart->get_ChartData()->get_SeriesGroups()->idx_get(0)->set_BubbleSizeScale(150);
        ...
    }
    catch(...)
    {
        __dispose_guard_0.SetCurrentException(std::current_exception());
