# The XYZ data for the 3D scatter chart as 3 random data series
$r = new RanSeries(0);
$xData = $r->getSeries2(100, 100, -10, 10);
$yData = $r->getSeries2(100, 0, 0, 20);

# Add a title to the chart using 20 points Times New Roman Italic font
$c->addTitle("3D Scatter Chart (1)  ", "timesi.ttf", 20);

# Set the center of the plot region at (350, 280), and set width x depth x height to 360 x 360 x 270
# pixels

# on the z value of the symbol
$c->addScatterGroup($xData, $yData, $zData, "", GlassSphere2Shape, 11, SameAsMainColor);

# Add a color axis (the legend) in which the left center is anchored at (645, 270). Set the length
# to 200 pixels and the labels on the right side.
$c->setColorAxis(645, 270, Left, 200, Right);

# Set the x, y and z axis titles using 10 points Arial Bold font
