Icon Donut Chart




This example modifies the Icon Pie Chart example by using a semi-transparent donut instead of a pie, and using metallic background color.

<?php
require_once("../lib/phpchartdir.php");

# The data for the pie chart
$data = array(72, 18, 15, 12);

# The depths for the sectors
$depths = array(30, 20, 10, 10);

# The labels for the pie chart
$labels = array("Sunny", "Cloudy", "Rainy", "Snowy");

# The icons for the sectors
$icons = array("sun.png", "cloud.png", "rain.png", "snowy.png");

# Create a PieChart object of size 400 x 300 pixels
$c = new PieChart(400, 300);

# Use the semi-transparent palette for this chart
$c->setColors(transparentPalette());

# Set the background to metallic light blue (CCFFFF), with a black border and 1 pixel 3D border
# effect,
$c->setBackground(metalColor(0xccccff), 0x000000, 1);

# Set directory for loading images to current script directory
# Need when running under Microsoft IIS
$c->setSearchPath(dirname(__FILE__));

# Set donut center at (200, 175), and outer/inner radii as 100/50 pixels
$c->setDonutSize(200, 175, 100, 50);

# Add a title box using 15pt Times Bold Italic font and metallic blue (8888FF) background color
$c->addTitle("Weather Profile in Wonderland", "Times New Roman Bold Italic", 15)->setBackground(
    metalColor(0x8888ff));

# Set the pie data and the pie labels
$c->setData($data, $labels);

# Add icons to the chart as a custom field
$c->addExtraField($icons);

# Configure the sector labels using CDML to include the icon images
$c->setLabelFormat(
    "<*block,valign=absmiddle*><*img={field0}*> <*block*>{label}\n{percent}%<*/*><*/*>");

# Draw the pie in 3D with variable 3D depths
$c->set3D2($depths);

# Set the start angle to 225 degrees may improve layout when the depths of the sector are sorted in
# descending order, because it ensures the tallest sector is at the back.
$c->setStartAngle(225);

# Output the chart
$viewer = new WebChartViewer("chart1");
$viewer->setChart($c, SVG);

# Include tool tip for the chart
$viewer->setImageMap($c->getHTMLImageMap("", "", "title='{label}: {value} days ({percent}%)'"));
