I managed to figure this out for anyone wanting assistance with how to do this. The end goal was to create a stacked chart dynamically with dynamically created sections. This is a potentially much more powerful stacked chart than the one I linked as it allows you to customise and add a ‘name’ to each of the stacks.
I’m also converting an international date format date (ie. 2018-09-23) to epoch for canvasJS to use, see function at the end.
var chart = new CanvasJS.Chart(“chartContainer”, { title: { text: “stackedBar using JSOdata” }, data: dataPointsR }); $.getJSON(“https://web address of json file here”, function(data) { $.each(data, function(key, val) { // key here is the name of the person as per my first post JSON. let dataPointR = []; $.each(val, function(key2, val2) { var DateEpoch = ConvertDate(key2); dataPointR.push({“x”: DateEpoch, “y”: val2}) // DateEpoch is 14348846000 and val2 is a number like 12 }) dataPointsR.push({“toolTipContent”:”{label}<br/>{name}, {m} {y}“,”showInLegend”:”true”,”type”:”stackedColumn”,”xValueType”:”dateTime”,”name”: key ,”dataPoints”: dataPointR}) }); chart.render();
});
function ConvertDate(dateToConvert) { var parts = dateToConvert.match(/(\d{4})\-(\d{2})\-(\d{2})/); var returnDate = Date.UTC(+parts[1], parts[2], +parts[3]);//, +parts[4], +parts[5]); return returnDate; }
