Aspose slides 'Area chart' series value not shown in the tooltip

Question

I am using aspose-slides-17.3-jdk16.jar for java. I have created the Area Chart using IChartDataWorkbook and I'm able to get the series values in the tool tip for all the charts except Area chart.

Following is the code I have done so far.

public class AreaChartSlide {

public static void main(String[] args) {

Presentation pres = new Presentation();

ISlide slide = pres.getSlides().get_Item(0);

// Creating the default chart
IChart chart = slide.getShapes().addChart(ChartType.Area, 0, 0, 500, 400);

// Getting the default chart data worksheet index
int defaultWorksheetIndex = 0;

// Getting the chart data worksheet
IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();

// Delete demo series
chart.getChartData().getSeries().clear();


// Add new series
chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 1, "Series 1"), chart.getType());
chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 0, 2, "Series 2"), chart.getType());

// Adding new categories
chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 1, 0, "Cat 1"));
chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 2, 0, "Cat 2"));

// Take first chart series
IChartSeries series = chart.getChartData().getSeries().get_Item(0);
// Now populating series data
series.getDataPoints().addDataPointForAreaSeries(fact.getCell(defaultWorksheetIndex, 1, 1, 20));
series.getDataPoints().addDataPointForAreaSeries(fact.getCell(defaultWorksheetIndex, 2, 2, 50));
// Setting fill color for series
series.getFormat().getFill().setFillType(FillType.Solid);
series.getFormat().getFill().getSolidFillColor().setColor(Color.RED);

// Take second chart series
series = chart.getChartData().getSeries().get_Item(1);
// Now populating series data
series.getDataPoints().addDataPointForAreaSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 30));
series.getDataPoints().addDataPointForAreaSeries(fact.getCell(defaultWorksheetIndex, 2, 2, 10));
series.getFormat().getFill().setFillType(FillType.Solid);
series.getFormat().getFill().getSolidFillColor().setColor(Color.GREEN);

pres.save("E:/PPT/Aspose.pptx", SaveFormat.Pptx);
System.out.println("done");

}

Below is the chart output i got

Any help would be greatly appreciated.

Answer 1

I have worked with shared sample code using Aspose.Slides for Java 17.5 on my end and have generated a presentation with Area chart having two series and two categories. I have opened the generated presentation in PowerPoint and able to observe the tool-tip text for both chart series. Please observe Series 1 and Series 2 tool-tip text display for your kind reference. I hope the shared information will be helpful. Please share, if I may help you further in this regard.

We are sorry for your inconvenience.

Answer 2

I have observed your comments and comparison image of tool-tip text display for Bar chart and Area chart. I like to add here that this is not some issue in Aspose.Slides charting engine but its a PowerPoint implementation. If you add an Area chart using PowerPoint, that too will display the point and series name in tool-tip text. Please observe the tool-tip text for slides 2 and 3 in this presentation . You can observe in this snapshot as well that tool-tip text for PowerPoint generated chart is also displaying series and point as it is being shown for similar chart type generated using Aspose.Slides. I hope the shared information will be helpful.
