drawBarChart is a jQuery plugin which makes it easier to visualize your array data in a vertical bar (column) chart.

Features:

  • Easy to use.
  • Built with plain JavaScript/HTML/CSS. No SVG and Canvas.
  • Custom x-axis and y-axis labels.
  • Supports for stacked column chart.
  • Allows you to specify the number of ticks.

How to use it:

1. Import the necessary Stylesheet and JavaScript files in the HTML file.

<link rel="stylesheet" href="/path/to/assets/stylesheets/styles.css" />
<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/assets/scripts/drawBarChart.js"></script>

2. Create a container to hold the column chart.

<div id="chart">
...
</div>

3. Prepare your chart data (numeric values) in a JS array.

let data = [5, 6, 4, 3, 12, 13, 12];

4. To create a stacked column chart, broken down the total amount into sub-amounts as follows:

let data = [[4, 6, 5], [6, 4, 7, 8], [6,3], 3, 12, 13, 12];

5. Config the column chart with the following settings.

let options = {
    width: 900,
    height: 600,
    barSpacing: 20,
    barLabelPosition: "top",
    barColour: ["#7B9E87", "#B6BE9C", "#D2D0BA", "#E5C1BD", "#A49CBF", "#9E7B91", "#BEE1E5"],
    barLegend: ["STEM Students", "Arts Students", "Psychology Students", "Nursing Students"],
    barLabelColour: ["white", "white", "white", "white"],
    barLabelFontSize: 14,
    // can be top, center, or bottom
    barLabelPosition: "center",
    // space between bar and top
    barPaddingTop: 50,
    legendFontSize: 15,
    legendBorderSize: 4,
    legendBoxSize: 10,
    xLabels: ["2017", "2018", "2019", "2020"],
    xLabelFontSize: 20,
    yTickCount: 4,
    yTickThickness: 5,
    yLabelFontSize: 15,
    yLabelDecimalCount: 0,
    yLabelColour: "black",
    yAxisTitle: "Number of Students",
    yAxisTitleFontSize: 17,
    chartTitle: "Graduating Class Size",
    titleFontSize: 30,
    titleFontColour: "black",
    chartBackgroundColour: "#5E747F",
    chartBorderColour: "black",
    borderWidth: 5
};

6. Determine the container element to hold the column chart. Default: <div />

let element = "#chart";

7. Draw a column chart on the page. That's it.

$(document).ready(
  drawBarChart(jQuery, data, options, element);
);
