CHART - Remove ZERO 0

This is the way I have dealt with this situation. When you are creating your data points, instead of putting a 0, put a null. So for example your data array will look like: [null,3,4,7,2] instead of [0,3,4,7,2] I have been working on Highcharts just got into one trouble the problem is when there is not any value exist for some data on the chart then it displays 0 on it which looks bad kindly checkout the following jsfiddle the labels on the chart gets populated by the following function but i am not able to put check on it that it should display only those bars whose values are above zero on the chart
