PODrawing graph with HighRoller / High Charts php
text
Body
copied!<p>I am using the php wrapper "highroller" to try and graph some data I have in a table in my database.</p> <p>Now, this code works (from the example):</p> <pre><code><?php require_once('../HighRoller/HighRoller.php'); require_once('../HighRoller/HighRollerSeriesData.php'); require_once('../HighRoller/HighRollerLineChart.php'); $chartData = array(5324, 7534, 6234, 7234, 8251, 10324); $series1 = new HighRollerSeriesData(); $series1->addName('myData')->addData($chartData); $linechart = new HighRollerLineChart(); $linechart->chart->renderTo = 'linechart'; $linechart->title->text = 'Hello HighRoller'; $linechart->yAxis->title->text = 'Total'; $linechart->addSeries($series1); ?> <head> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>  <?php echo HighRoller::setHighChartsLocation("../highcharts/highcharts.js");?> </head> <body> <div id="linechart"></div> <script type="text/javascript"> <?php echo $linechart->renderChart();?> </script> </body> </code></pre> <p>However, I am trying to edit the $chartdata = array(5324,...) so that I can pull this from a database. Here is my attempt:</p> <pre><code>$connection = mysql_connect(#,#,#) or die("Couldn't connect to the server."); $database = mysql_select_db(#, $connection) or die ("Couldn't select the correct database."); $result = mysql_query("SELECT price FROM highroller"); while ($row = mysql_fetch_array($result)){ $priceData[] = $row['price']; } $chartData = $priceData; $linechart = new HighRollerLineChart(); $linechart->chart->renderTo = 'linechart'; $linechart->title->text = 'Line Chart'; $series1 = new HighRollerSeriesData(); $series1->addName('myData')->addData($chartData); $linechart->addSeries($series1); </code></pre> <p>Now, I am not sure why this does not work as the $priceData is an array just like the previous static array.</p> <p>Also, for reference, here is the function for 'addData' from the library:</p> <pre><code>/** add data to plot in your chart * @param $chartdata - array, data provided in 1 of 3 HighCharts supported array formats (array, assoc array or mult-dimensional array) * @return void */ public function addData($chartdata){ if(!is_array($chartdata)){ die("HighRoller::addData() - data format must be an array."); } $this->series = array($chartdata); } </code></pre>
