Hi,

I am not able to change the font style and size of chart title.
here i am providing the source code:


Presentation pres = new Presentation();

//Access first slide
ISlide sld = pres.Slides[0];

// Add chart with default data
IChart chart = sld.Shapes.AddChart(ChartType.ClusteredColumn, 0, 0, 500, 500);
chart.PlotArea.Height = 0.5f;
chart.ChartTitle.AddTextFrameForOverriding(“Sample Title”);
chart.ChartTitle.TextFrameForOverriding.TextFrameFormat.CenterText = NullableBool.True;
chart.ChartTitle.TextFormat.PortionFormat.FontHeight = 10f;
chart.ChartTitle.TextFormat.PortionFormat.LatinFont = new FontData(“Arial”);
chart.HasTitle = true;

//Set first series to Show Values
chart.ChartData.Series[0].Labels.DefaultDataLabelFormat.ShowValue = true;

//Setting the index of chart data sheet
int defaultWorksheetIndex = 0;

//Getting the chart data worksheet
IChartDataWorkbook fact = chart.ChartData.ChartDataWorkbook;

//Delete default generated series and categories
chart.ChartData.Series.Clear();
chart.ChartData.Categories.Clear();
int s = chart.ChartData.Series.Count;
s = chart.ChartData.Categories.Count;

//Adding new series
chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 0, 1, “Series 1”), ChartType.ClusteredColumn);
chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 0, 2, “Series 2”), ChartType.StackedColumn);
chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 0, 3, “cagr”), ChartType.Line);

//Adding new categories
chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 1, 0, “Caetegoty 1”));
chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 2, 0, “Caetegoty 2”));
chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 3, 0, “Caetegoty 3”));

//Take first chart series
IChartSeries series = chart.ChartData.Series[0];

// Now populating series data

series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 1, 1, -20));
series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 2, 1, 50));
series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 3, 1, 30));

chart.ChartData.Series[0].PlotOnSecondAxis = true;
//Setting fill color for series
series.Format.Fill.FillType = FillType.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Red;
chart.ChartData.Series[0].InvertIfNegative = false;
chart.ChartData.Series[1].InvertIfNegative = false;
chart.ChartData.Series[2].InvertIfNegative = false;
//Take second chart series
series = chart.ChartData.Series[1];

//Now populating series data
series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 1, 2, 30));
series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 2, 2, 10));
series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 3, 2, 60));

//Setting fill color for series
series.Format.Fill.FillType = FillType.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Green;
series = chart.ChartData.Series[2];
series.DataPoints.AddDataPointForLineSeries(fact.GetCell(defaultWorksheetIndex, 1, 3, “”));
series.DataPoints.AddDataPointForLineSeries(fact.GetCell(defaultWorksheetIndex, 2, 3, 50));
series.DataPoints.AddDataPointForLineSeries(fact.GetCell(defaultWorksheetIndex, 3, 3, 50));
series.Format.Fill.FillType = FillType.Solid;
series.Format.Fill.SolidFillColor.Color = Color.Olive;
chart.DisplayBlanksAs = DisplayBlanksAsType.Gap;
chart.ChartData.Series[0].PlotOnSecondAxis = true;
pres.Save(“C:\Presentations\AsposeChart.pptx”, Aspose.Slides.Export.SaveFormat.Pptx);

Hi Deepak,

I have worked over your code and suggest you to please add following lines in your code and replace them with existing ones where you are setting chart title. I hope this will work on your end.

ITextFrame frm = chart.ChartTitle.AddTextFrameForOverriding(“Sample Title”);
IPortion chartTitle = frm.Paragraphs[0].Portions[0];
chartTitle.PortionFormat.LatinFont = new FontData(“Arial”);
chartTitle.PortionFormat.FillFormat.FillType = FillType.Solid;
chartTitle.PortionFormat.FillFormat.SolidFillColor.Color = Color.Gray;
chartTitle.PortionFormat.FontHeight = 10f;

Many Thanks,
