Multiple Charts with unknown count

    I was wondering if it is possible to create any number of charts depending on what my query returns. For instance, my query will return any number of budget goals from a database, and depending on how many budget goals the user has set will dictate how many bar charts I make. Each bar chart will be the same format but will have different data. Normally I would just pre-define the chart specs and throw in the data, but i’m not sure how I would do that if I don’t know ahead of time how many charts I will need to create.

    BTW I am writing this in PHP/HTML/CSS using javascript for the canvas.js elements.


    If it helps this is the javascript for the chart I want multiple of…

    var chart = new CanvasJS.Chart(“BudgetGoal”, {
    animationEnabled: true,
    backgroundColor: “#F0F0F0″,
    //height of bar (eliminates whitespace)
    height: 100,
    //width of bar
    dataPointWidth: 30,
    axisX: {
    //hide axis label (need both of these)
    tickLength: 0,
    labelFormatter: function(){
    return ” “;
    axisY: {
    prefix: “$”,
    //sets budget goal max
    lineThickness: 0,
    maximum: 200 <== variable that will differ
    toolTip: {
    shared: true
    cursor: “pointer”,
    itemclick: toggleDataSeries
    data: [{
    type: “stackedBar”,
    name: “Spent”,
    yValueFormatString: “$#,##0″,
    dataPoints: [
    { label: “Shopping (3/15/18 – 4/15/18)”, y: 90 } <== variables that will differ
    type: “stackedBar”,
    name: “Money left”,
    //showInLegend: “true”,
    //xValueFormatString: “DD, MMM”,
    yValueFormatString: “$#,##0″,
    dataPoints: [
    { label: “Shopping (3/15/18 – 4/15/18)”, y: 110 } <== variables that will differ

    and here is the div tag in the html
    <div id=”BudgetGoal” style=”height: 100px; width: 100%;”></div>

    NVM I found a similar fiddle here that helped a ton for anyone reading this. https://jsfiddle.net/862dpfLw/
