使用php codeigniter的HTML图形

有人能帮我把html5 cnavasjs用于图形吗？图形是重复的 php代码是

window.onload = function () {
                            var chart = new CanvasJS.Chart("chartContainer", {
                                theme: "theme2",//theme1
                                animationEnabled: true,
                                 zoomEnabled:true,
                                title:{
                                    text: "Basic Column Chart Of Student in Current Year"   ,
                                    fontColor: "#0A89C4"
                               },

                                data: [              
                                {

                  // Change type to "bar", "splineArea", "area", "spline", "pie",etc.
                                    type: "column",

                                    dataPoints: [
                                         <?php foreach ($std as $row3){?>
                                    { label: "<?php echo $row3['obj_full_month'];?>", y: <?php echo count($row3['obj_student_id']);?> },

                                    <?php
                                        }
                                     ?>
                                    ]

                                }

                                ]

                            });

                            chart.render();
                        }

您是否尝试过使用Distinct：

选择Distinct obj\U full\U MOUNT，obj\U SUSTOMENT\U id FROM…

？您有3个结果。这是预期的还是像Mahmoud所说的由sql查询引起的重复？您的数据有什么问题？你想做什么？是否要消除重复数据？或者你想把它们加起来？您可能需要计算每个月的学生人数？

SELECT * FROM `obj_organisation`,`obj_student`,`obj_student_graph`
                        WHERE obj_organisation.obj_org_id = obj_student.obj_org_id
                        AND
                        obj_organisation.obj_org_id = obj_student_graph.obj_org_id
                        AND
                        obj_student.obj_student_id = obj_student_graph.obj_student_id
                        AND
                        obj_student_graph.obj_org_id = '$id'
                        AND
                        obj_student_graph.obj_year = '$year'!
