Creating a Chart from Scratch in Ruby

Aspose.Slides - Creating Normal Chart

To Create Normal Chart using Aspose.Slides Java for Ruby, call create_normal_chart method of CreateChart module. Here you can see example code.

Ruby Code


 def create_normal_chart()

    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 = sld.getShapes().addChart(Rjb::import('com.aspose.slides.ChartType').ClusteredColumn, 0, 0, 500, 500)

    # Setting chart Title

    # chart.ChartTitle.TextFrameForOverriding.Text = "Sample 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()

    s = chart.getChartData().getSeries().size()

    s = chart.getChartData().getCategories().size()

    # Adding 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, "Caetegoty 1"))

    chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 2, 0, "Caetegoty 2"))

    chart.getChartData().getCategories().add(fact.getCell(defaultWorksheetIndex, 3, 0, "Caetegoty 3"))

    # Take first chart series

    series = chart.getChartData().getSeries().get_Item(0)

    # Now populating series data

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

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

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

    # Setting fill color for series

    series.getFormat().getFill().setFillType(Rjb::import('com.aspose.slides.FillType').Solid)

    series.getFormat().getFill().getSolidFillColor().setColor(Rjb::import('java.awt.Color').RED)


    # Take second chart series

    series = chart.getChartData().getSeries().get_Item(1)

    # Now populating series data

    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 1, 2, 30))

    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 2, 2, 10))

    series.getDataPoints().addDataPointForBarSeries(fact.getCell(defaultWorksheetIndex, 3, 2, 60))

    # Setting fill color for series

    series.getFormat().getFill().setFillType(Rjb::import('com.aspose.slides.FillType').Solid)

    series.getFormat().getFill().getSolidFillColor().setColor(Rjb::import('java.awt.Color').GREEN)

    # create custom labels for each of categories for new series

    # first label will be show Category name

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

    lbl.getDataLabelFormat().setShowCategoryName(true)

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

    lbl.getDataLabelFormat().setShowSeriesName(true)

    # Show value for third label

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

    lbl.getDataLabelFormat().setShowValue(true)

    lbl.getDataLabelFormat().setShowSeriesName(true)

    lbl.getDataLabelFormat().setSeparator ("/")

    # Save presentation with chart

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

    puts "Created normal chart, please check the output file."

end   

Aspose.Slides - Creating Scattered Chart

To Create Scattered Chart using Aspose.Slides Java for Ruby, call create_scatter_chart method of CreateChart module. Here you can see example code.

Ruby Code


 def create_scatter_chart()

    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

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

    # Creating the default chart

    chart = slide.getShapes().addChart(Rjb::import('com.aspose.slides.ChartType').ScatterWithSmoothLines, 0, 0, 400, 400)

    # Getting the default chart data worksheet index

    defaultWorksheetIndex = 0

    # Getting the chart data worksheet

    fact = chart.getChartData().getChartDataWorkbook()

    # Delete demo series

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

    # Add new series

    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 1, 1, "Series 1"), chart.getType())

    chart.getChartData().getSeries().add(fact.getCell(defaultWorksheetIndex, 1, 3, "Series 2"), chart.getType())

    # Take first chart series

    series = chart.getChartData().getSeries().get_Item(0)

    # Add new point (1:3) there.

    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 2, 1, 1), fact.getCell(defaultWorksheetIndex, 2, 2, 3))

    # Add new point (2:10)

    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 3, 1, 2), fact.getCell(defaultWorksheetIndex, 3, 2, 10))

    # Edit the type of series

    series.setType(Rjb::import('com.aspose.slides.ChartType').ScatterWithStraightLinesAndMarkers)

    # Changing the chart series marker

    series.getMarker().setSize(10)

    series.getMarker().setSymbol(Rjb::import('com.aspose.slides.MarkerStyleType').Star)

    # Take second chart series

    series = chart.getChartData().getSeries().get_Item(1)

    # Add new point (5:2) there.

    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 2, 3, 5), fact.getCell(defaultWorksheetIndex, 2, 4, 2))

    # Add new point (3:1)

    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 3, 3, 3), fact.getCell(defaultWorksheetIndex, 3, 4, 1))

    # Add new point (2:2)

    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 4, 3, 2), fact.getCell(defaultWorksheetIndex, 4, 4, 2))

    # Add new point (5:1)

    series.getDataPoints().addDataPointForScatterSeries(fact.getCell(defaultWorksheetIndex, 5, 3, 5), fact.getCell(defaultWorksheetIndex, 5, 4, 1))

    # Changing the chart series marker

    series.getMarker().setSize(10)

    series.getMarker().setSymbol(Rjb::import('com.aspose.slides.MarkerStyleType').Circle)

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

    puts "Created scatter chart, please check the output file."
