Hello Everyone,

I am trying to display a graph, but it is not working. I see that the variables is getting the correct value, so maybe the addSeries is not recognizing the variables. Can anyone help me? See the code below:

    <!DOCTYPE html>
        <html >
        //connect to database
        $con = mysql_connect("localhost", "test", "test") or die('Sorry, could not connect to database server');
        mysql_select_db("brazil", $con) or die('Sorry, could not connect to database');

        //total number of participants
        $query1 = "SELECT participantsExpected from ac where identity =4";
        //number of participants in neoadjuvant chemoterapy
        $query2 = "Select participantsEnrolled from ac where identity=4";
        //number of participants in surgery
        $query3 = "SELECT participantsExpected from ac where identity =2";
        //number of participants off study
        $query4 = "Select participantsEnrolled from ac where identity=1";
        //number of participants expected
        $query5 = "Select participantsExpected from ac where identity=1";
        //number of participants unassigned
        $query6="Select participantsEnrolled from ac where identity=2";

        $result1 = mysql_query($query1) or die ('Could not find total');
        $res1= mysql_fetch_array($result1);
        $totalp[] = $res1['participantsExpected'];
        //echo ($totalp);

        $result2 = mysql_query($query2) or die ('Could not find neo chemoterapy');
        $res2 = mysql_fetch_array($result2);
        $chemop[] = $res2['participantsEnrolled'];
        $chemop= json_encode($chemop);

        $result3 = mysql_query($query3) or die ('Could not find surgery');
        $res3 = mysql_fetch_array($result3);
        $surgeryp[] = $res3['participantsExpected'];
        $surgeryp = json_encode($surgeryp);

        $result4 = mysql_query($query4) or die ('Could not find off study');
        $res4 = mysql_fetch_array($result4);
        $offp[] = $res4['participantsEnrolled'];
        $offp = json_encode($offp);

        $result5 = mysql_query($query5) or die ('Could not find expected');
        $res5 = mysql_fetch_array($result5);
        $expectp[] = $res5['participantsExpected'];
        $expectp = json_encode($expectp);

        $result6 = mysql_query($query6) or die ('Could not find unassigned');
        $res6 = mysql_fetch_array($result6);
        $unassignp[] = $res6['participantsEnrolled'];
        $unassignp= json_encode($unassignp);

         //  We want to plot StackedColumns
        //  We want to use Markers
        //  We'll use default x/y axes
        //we'll use Legend
        // Wait until the DOM is ready
     function(Chart, theme) {

        // Define the data

        var total= <?php echo ($totalp); ?>;
        var chemo = <?php echo ($chemop); ?>;
        var surgery = <?php echo ($surgeryp); ?>;
        var offstudy = <?php echo ($offp); ?>;
        var expected = <?php echo ($expectp); ?>;
        var unassigned = <?php echo ($unassignp); ?>;

        // Create the chart within it's "holding" node
        var chart = new Chart("chartNode");

        // Set the theme

        // Add the only/default plot
        chart.addPlot("default", {
           type: "Columns",
           markers: true,
           shadows: {dx:2, dy:2, dw:2},
           gap: 2

        // Add axes
        chart.addAxis("x", {title:"Arms", titleOrientation: "away", minorLabels: false, labels:[{value:0, text:""}, {value:1, text:""}, {value:2, text:"Off-Study"},{value:3, text: "Expected"}, {value:4, text:"Actual"}, {value:5, text:""}], rotation:-90});
        chart.addAxis("y", {title: "Participants", vertical: true, includeZero: true, ticks:true, majorLabels:false, minorLabels: false });

        // Add the series of data
        chart.addSeries("Off-Study", offstudy, {fill:"gray"});
        chart.addSeries("Expected", expected, {fill:"gray"});
        chart.addSeries("Unassigned", [0,0,0,unassigned,0], {stroke:"#FF0000", fill:"#CC6600"});
        chart.addSeries("Surgery", [0,0,0,surgery,0], {stroke:"#FFFF00", fill:"#FFFF33"});
        chart.addSeries("Neo Chemoterapy", [0,0,0,chemo,0], {stroke:"#FF0099", fill:"#FEA9F3"});
        chart.addSeries("Total", [0,0,0,total,0], {stroke:"black", fill:"black"});  

        // Render the chart!
        var legend1 = new dojox.charting.widget.SelectableLegend({chart: chart, horizontal:true}, "legend1");



    <div id="chartNode" style="width:500px;height:450px;"></div>
    <div id="legend1"></div>

I guess the value format is incorrect. I am trying to get a specific value so it can be placed in the addSeries and display the graph. For now, I see I am getting the value in this format ["42"], and maybe that's the reason the addSeries can't recognize it. How can I get the clean value?


I found the problem:

I just changed the following lines for all the queries results.

 $result1 = mysql_query($query1) or die ('Could not find total');
    $res1= mysql_fetch_array($result1);
    $totalp = $res1[0];
    //echo ($totalp);
