Legend display error with one series

Hi Folks,

I found a strange bug by creating / modifying charts with Aspose.Slides under .NET

For example I have 3 categories and 1 series the legend shows the series name(s) - so far everything is correct.

But if i color only one datapoint with this code:


chart.ChartData.Series[0].DataPoints[1].Format.Fill.FillType = FillType.Solid;

chart.ChartData.Series[0].DataPoints[1].Format.Fill.SolidFillColor.Color = Color.Black;


The legend no longer shows the series - now it display the list of categories… and it is not possible to change it to the series list - not even in powerpoint…


- With Coloring -> Attachment: “AsposeChart_error.pptx”

- Without Coloring -> Attachment: “AsposeChart_success.pptx”

Here are my full code:


Presentation pres = new Presentation();

ISlide sld = pres.Slides[0];

IChart chart = sld.Shapes.AddChart(ChartType.ClusteredBar, 100, 100, 400, 400);

int defaultWorksheetIndex = 0;

IChartDataWorkbook fact = chart.ChartData.ChartDataWorkbook;



chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 1, 0, “a”));

chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 2, 0, “b”));

chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 3, 0, “c”));

chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 0, 1, “series”), chart.Type);

chart.ChartData.Series[0].DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 1, 1, 0));

chart.ChartData.Series[0].DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 2, 1, 9.553967186161332));

chart.ChartData.Series[0].DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 3, 1, 5.473745114704258));

chart.HasLegend = true;

// with this code - the legend show the categories and not the series list

// chart.ChartData.Series[0].DataPoints[1].Format.Fill.FillType = FillType.Solid;

// chart.ChartData.Series[0].DataPoints[1].Format.Fill.SolidFillColor.Color = Color.Black;


License licence = new License();


pres.Save(“AsposeChart.pptx”, Aspose.Slides.Export.SaveFormat.Pptx);


I work under Windows 7 64 Bit with Aspose.Slides 15.4.0 .NET
