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 >
        <head>
        <?php
        //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'];
        $totalp=json_encode($totalp);
        //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);
        //print_r($offp);

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

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

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?

Thanks

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 = $res1[0];
    //$totalp=json_encode($totalp);
    //echo ($totalp);
