Setting Pie Chart Sector Colors in Ruby

Aspose.Slides - Setting Pie Chart Sector Colors

To Set Pie Chart Sector Colors using Aspose.Slides Java for Ruby, simply invoke SetPieChartColors module. Here you can see example code.

Ruby Code

 data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'



\# Instantiate Presentation class that represents the presentation file

pres = Rjb::import('com.aspose.slides.Presentation').new

\# Access first slide

sld = pres.getSlides().get_Item(0)

\# Add chart with default data

chart_type = Rjb::import('com.aspose.slides.ChartType')

chart = sld.getShapes().addChart(chart_type.Pie, 100, 100, 400, 400)

\# Setting chart Title

chart.getChartTitle().addTextFrameForOverriding("Sample Title")

chart.getChartTitle().getTextFrameForOverriding().getTextFrameFormat().setCenterText(Rjb::import('com.aspose.slides.NullableBool').True)

chart.getChartTitle().setHeight(20)

chart.hasTitle(true)

\# Set first series to Show Values

chart.getChartData().getSeries().get_Item(0).getLabels().getDefaultDataLabelFormat().setShowValue(true)

\# Setting the index of chart data sheet

defaultWorksheetIndex = 0

\# Getting the chart data worksheet

fact = chart.getChartData().getChartDataWorkbook()

\# Delete default generated series and categories

chart.getChartData().getSeries().clear()

chart.getChartData().getCategories().clear()

\# Adding new categories

chart.getChartData().getCategories().add(fact.getCell(0, 1, 0, "First Qtr"))

chart.getChartData().getCategories().add(fact.getCell(0, 2, 0, "2nd Qtr"))

chart.getChartData().getCategories().add(fact.getCell(0, 3, 0, "3rd Qtr"))

\# Adding new series

series = chart.getChartData().getSeries().add(fact.getCell(0, 0, 1, "Series 1"), chart.getType())

\# Now populating series data

series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 1, 1, 20))

series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 50))

series.getDataPoints().addDataPointForPieSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 30))

\# Not working in new version

\# Adding new points and setting sector color

chart.getChartData().getSeriesGroups().get_Item(0).isColorVaried(true)

fill_type = Rjb::import('com.aspose.slides.FillType')

line_style = Rjb::import('com.aspose.slides.LineStyle')

color = Rjb::import('java.awt.Color')

line_dash_style = Rjb::import('com.aspose.slides.LineDashStyle')

preset_color = Rjb::import('com.aspose.slides.PresetColor')

point = series.getDataPoints().get_Item(0)

point.getFormat().getFill().setFillType(fill_type.Solid)

point.getFormat().getFill().getSolidFillColor().setColor(color.CYAN)

\# Setting Sector border

point.getFormat().getLine().getFillFormat().setFillType(fill_type.Solid)

point.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(color.GRAY)

point.getFormat().getLine().setWidth(3.0)

point.getFormat().getLine().setStyle(line_style.ThinThick)

point.getFormat().getLine().setDashStyle(line_dash_style.DashDot)


point1 = series.getDataPoints().get_Item(1)

point1.getFormat().getFill().setFillType(fill_type.Solid)

point1.getFormat().getFill().getSolidFillColor().setColor(Rjb::import('java.awt.Color').new(preset_color.Brown))

\# Setting Sector border

point1.getFormat().getLine().getFillFormat().setFillType(fill_type.Solid)

point1.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(color.BLUE)

point1.getFormat().getLine().setWidth(3.0)

point1.getFormat().getLine().setStyle(line_style.Single)

point1.getFormat().getLine().setDashStyle(line_dash_style.LargeDashDot)

point2 = series.getDataPoints().get_Item(2)

point2.getFormat().getFill().setFillType(fill_type.Solid)

point2.getFormat().getFill().getSolidFillColor().setColor(Rjb::import('java.awt.Color').new(preset_color.Coral))

\# Setting Sector border

point2.getFormat().getLine().getFillFormat().setFillType(fill_type.Solid)

point2.getFormat().getLine().getFillFormat().getSolidFillColor().setColor(color.RED)

point2.getFormat().getLine().setWidth(2.0)

point2.getFormat().getLine().setStyle(line_style.ThinThin)

point2.getFormat().getLine().setDashStyle(line_dash_style.LargeDashDotDot)

\# Create custom labels for each of categories for new series

lbl1 = series.getDataPoints().get_Item(0).getLabel()

lbl1.getDataLabelFormat().setShowValue(true)

lbl2 = series.getDataPoints().get_Item(1).getLabel()

lbl2.getDataLabelFormat().setShowValue (true)

lbl2.getDataLabelFormat().setShowLegendKey(true)

lbl2.getDataLabelFormat().setShowPercentage(true)

lbl3 = series.getDataPoints().get_Item(2).getLabel()

lbl3.getDataLabelFormat().setShowSeriesName(true)

lbl3.getDataLabelFormat().setShowPercentage (true)

\# Showing Leader Lines for Chart

series.getLabels().getDefaultDataLabelFormat().setShowLeaderLines(true)

\# Setting Rotation Angle for Pie Chart Sectors

chart.getChartData().getSeriesGroups().get_Item(0).setFirstSliceAngle(180)

\# Save presentation with chart

pres.save(data_dir + "AsposePieChart.pptx", Rjb::import('com.aspose.slides.SaveFormat').Pptx)

puts "Set pie chart sector colors, please check the output file."
