Setting Pie Chart Sector Colors in PHP

Aspose.Slides - Setting Pie Chart Sector Colors

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

PHPCode

 $pres = new Presentation();

\# Access first slide

$sld = $pres->getSlides()->get_Item(0);

\# Add chart with default data

$chart_type = new ChartType();

$chart = $sld->getShapes()->addChart($chart_type->Pie, 100, 100, 400, 400);

$nullableBool=new NullableBool();

\# Setting chart Title

$chart->getChartTitle()->addTextFrameForOverriding("Sample Title");

$chart->getChartTitle()->getTextFrameForOverriding()->getTextFrameFormat()->setCenterText($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 = new FillType();

$line_style = new LineStyle();

$color = new Color();

$line_dash_style = new LineDashStyle();

$preset_color = new 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);

$point1->getFormat()->getFill()->getSolidFillColor()->setColor(new Color($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);

$point2->getFormat()->getFill()->getSolidFillColor()->setColor(new Color($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

$save_format = new SaveFormat();

$pres->save($dataDir . "AsposePieChart.pptx", $save_format->Pptx);

print "Set pie chart sector colors, please check the output file.".PHP_EOL;
