Class Legend

Encapsulates the object that represents the chart legend.

Example:

$workbook = new cells\Workbook();
$worksheet = $workbook->getWorksheets()->get(0);
$cells = $worksheet->getCells();
$cells->get("A1")->putValue(50);
$cells->get("A2")->putValue(100);
$cells->get("A3")->putValue(150);
$cells->get("A4")->putValue(200);
$cells->get("B1")->putValue(60);
$cells->get("B2")->putValue(32);
$cells->get("B3")->putValue(50);
$cells->get("B4")->putValue(40);
$cells->get("C1")->putValue("Q1");
$cells->get("C2")->putValue("Q2");
$cells->get("C3")->putValue("Y1");
$cells->get("C4")->putValue("Y2");
//Adding a chart to the worksheet
$chartIndex = $worksheet->getCharts()->add(cells\ChartType::COLUMN, 5, 0, 15, 5);
//Accessing the instance of the newly added chart
$chart = $worksheet->getCharts()->get($chartIndex);
//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B4"
$chart->getNSeries()->add("A1:B4", true);
//Setting the data source for the category data of NSeries
$chart->getNSeries()->setCategoryData("C1:C4");

$legend = $chart->getLegend();
//Legend is at right side of chart by default
//If the legend is at left or right side of the chart, setting Legend->X property will not take effect
//If the legend is at top or bottom side of the chart, setting Legend->Y property will not take effect
$legend->setY(1500);
$legend->setWidth(50);
$legend->setHeight(50);
//Set legend's position
$legend->setPosition(cells\LegendPositionType::LEFT);
