This example demonstrates how to control text styles, text colors, background colors and text box border effects.
In the chart above, the title, the sector labels, and the legends all have different fonts, text colors, background colors, and border styles.

setPieSize(150, 150, 100);
#Add a title to the pie chart using Monotype Corsiva ("mtcorsva")/20 points/deep
#blue (0x000080) as font
$c->addTitle("Project Cost Breakdown", "mtcorsva.ttf", 20, 128);
#Draw the pie in 3D
$c->set3D();
#Add a legend box using 12 points Times New Romans Bold ("timesbd.ttf") font.
#Set background color to light grey (0xd0d0d0), with a 1 pixel 3D border.
$legendObj = $c->addLegend(340, 80, true, "timesbd.ttf", 12);
$legendObj->setBackground(0xd0d0d0, 0xd0d0d0, 1);
#Set the default font for all sector labels to Impact/8 points/dark green
#(0x008000).
$c->setLabelStyle("impact.ttf", 8, 0x8000);
#Set the pie data and the pie labels
$c->setData($data, $labels);
#Explode the 3rd sector
$c->setExplode(2, 40);
#Use Impact/12 points/red as label font for the 3rd sector
$sectorObj = $c->sector(2);
$sectorObj->setLabelStyle("impact.ttf", 12, 0xff0000);
#Use Arial/8 points/deep blue as label font for the 5th sector. Add a background
#box using the sector fill color (SameAsMainColor), with a black (0x000000) edge
#and 2 pixel 3D border.
$sectorObj = $c->sector(4);
$labelStyleObj = $sectorObj->setLabelStyle("", 8, 0x80);
$labelStyleObj->setBackground(SameAsMainColor, 0x0, 2);
#Use Times New Romans/8 points/light red (0xff9999) as label font for the 6th
#sector. Add a dark blue (0x000080) background box with a 2 pixel 3D border.
$sectorObj = $c->sector(0);
$labelStyleObj = $sectorObj->setLabelStyle("times.ttf", 8, 0xff9999);
$labelStyleObj->setBackground(0x80, Transparent, 2);
#Use Impact/8 points/deep green (0x008000) as label font for 7th sector. Add a
#yellow (0xFFFF00) background box with a black (0x000000) edge.
$sectorObj = $c->sector(6);
$labelStyleObj = $sectorObj->setLabelStyle("impact.ttf", 8, 0x8000);
