How to hide zero data value from chartjs?

Question

i have built a chart using chartjs. I'm trying to remove those data value that is zero from the chart. I wrote a function to display only value that is non-zero but it doesn't seem to work. Can anyone help?

Below is my Javascript

var ctx = document.getElementById('myChart2').getContext('2d');
            var myChart = new Chart(ctx, {
                type:<?php echo $chartype; ?>,
                data : {
                  labels: [<?php echo $datelist_2; ?>], <!--label name->
                  datasets: [
                      { 
                        label: "Sales",
                        data: [<?php echo $atlasdata2; ?>],
                        backgroundColor: 'rgb(248, 108, 108, 0.6)'
                      }                   
                      ]
                },
                .......
                .......
                .......
                      plugins: {
                              datalabels: {
                                 display: true,
                                 align: 'center',
                                 anchor: 'center',
                                 formatter: function(value, index, values) {
                                     if(value != 0){
                                         value = value.toString();
                                         value = value.split(/(?=(?:...)*$)/);
                                         value = value.join(',');
                                         return value;
                                     }
                                    }
                              }
                           }
                    }

                });

How my chart looks like currently?

Finally solve myself. its a silly answer. I need to add an else statement in order to make the zero disappear.

 plugins: {
            datalabels: {
                display: true,
                align: 'center',
                anchor: 'center',
                formatter: function(value, index, values) {
                            if(value >0 ){
                                value = value.toString();
                                value = value.split(/(?=(?:...)*$)/);
                                value = value.join(',');
                                return value;
                            }else{
                                value = "";
                                return value;
                            }
                        }
                    }
             }
