Can someone complete a project on control chart implementation? I have been working on this so far, but any other ideas, how I could take back control chart, to create code for the controls I had? EDIT: I have now tried, but i am not sure how to integrate the data into the chart. If the user set a value to “1” to control the data, then the user controls the chart, the control should trigger a refresh in the page. So perhaps i have to do something like this: function generate() { $.get(“project.data.html”, function(data) { if ($(data).property(‘data-key-value’) == ”) { if ($(data).dataProperty(‘data-key-value’)!= ”) { $(‘#project-items-header’).append(‘‘ + $(‘#project-items-header’).val() + ‘‘); }); } else { SetData() } $.each(data, function (i, item) { if ($(data).dataProperty(‘data-key-value’) == ”) { SetData() } }); }); } else { SetData() } }); } Another way to set data-key-value is with setData(). I have not done it in any other years myself, but I do always find a solution without any jQuery. Is there any issue about removing event listeners? A: The if ($(data).datasource) is not related to your data object. That’s why the first and second checkboxes add and remove
