Description:
------------
I am unable to view graph using Image_Graph, can you please let me know
the steps to debug this issue .
Test script:
---------------
function doChart($table, $fields, $appName, $node = "", $nodeTbl = "") {
global $date, $site, $statsDB;
include "Image/Graph.php";
if ( file_exists("/usr/openwin/lib/X11/fonts/TrueType/LiberationSans-Regular.ttf" ) ) {
$fontPath = "/usr/openwin/lib/X11/fonts/TrueType/LiberationSans-Regular.ttf";
} else if ( file_exists("/usr/share/fonts/liberation/LiberationSans-Regular.ttf") ) {
$fontPath = "/usr/share/fonts/liberation/LiberationSans-Regular.ttf";
}
$graph =& Image_Graph::factory("graph",array(640,400));
$font =& $graph->addNew("font",$fontPath);
$font->setSize(8);
$graph->setFont($font);
//Image_Graph::factory('title',array("EBA " . strtoupper($appName) . " Metrics: " . $fields, 12)),
//Image_Graph::factory('title',array($date,8)),
$graph->add(
Image_Graph::vertical(
Image_Graph::vertical(
Image_Graph::factory('title',array("",12)),
Image_Graph::factory('title',array("", 8)),
80
),
Image_Graph::vertical(
$plotArea = Image_Graph::factory('plotarea'),
$legend = Image_Graph::factory('legend'),
85
),
9)
);
$legend->setPlotArea($plotArea);
$legend->setFillColor("#cccccc@0.5");
$gridY =& $plotArea->addNew('line_grid', null, IMAGE_GRAPH_AXIS_Y);
$gridY->setLineColor('gray@0.1');
$fieldArr = explode(",", $fields);
$datasets = array();
foreach ($fieldArr as $f) {
$datasets[$f] =& Image_Graph::factory('dataset');
}
$nodeFilter = "";
$tables = "eba_mdc," . $table . ",sites";
if ($node != "") {
$nodeFilter = $table . ".moid_id = eba_moid.id AND eba_moid.name = '" . $node . "' AND ";
$tables = "eba_moid," . $tables;
}
$sql = "SELECT DATE_FORMAT(begin_time,'%H:%i') AS begin_time," . $fields . " FROM " . $tables ." WHERE " .
"begin_time BETWEEN '" . $date . " 00:00:00' AND '" . $date . " 23:59:59' AND " .
"neun='" . $appName . "' AND siteid=sites.id AND sites.name = '" . $site . "' AND " . $nodeFilter .
"mdc_id=eba_mdc.id ORDER BY begin_time";
$statsDB->query($sql);
$yMax = 0;
while ($row = $statsDB->getNextNamedRow()) {
foreach ($row as $key => $val) {
if ($key == "begin_time") {
$xVal = $val;
} else {
if (isset($val) && $val != "" && isset($datasets[$key])) {
if ($val > $yMax) $yMax = $val;
$datasets[$key]->addPoint($xVal, $val);
}
}
}
}
$colours = array("red","orange","yellow","green","blue","indigo","violet");
$i = 0;
foreach ($datasets as $key => $dataset) {
$plot =& $plotArea->addNew('line', array(&$dataset));
$plot->setTitle($key);
$plot->setLineColor($colours[$i++]);
}
$xAxis =& $plotArea->getAxis(IMAGE_GRAPH_AXIS_X);
$xAxis->setTitle("Time");
$xAxis->setLabelInterval(8);
$yAxis =& $plotArea->getAxis(IMAGE_GRAPH_AXIS_Y);
$yAxis->setTitle("Count", 'vertical');
$yAxis->forceMaximum($yMax * 1.1);
$graph->setPadding(10);
$graph->done();
}
Expected result:
----------------
it must display image
Actual result:
--------------
image can't be displayed
