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:



{code}

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

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

{/code}



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…



Examples:



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

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



Here are my full code:





{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.Series.Clear();

chart.ChartData.Categories.Clear();



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();

licence.SetLicense(“Aspose.Slides.lic”);



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

{/code}





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