A column chart is a type of bar chart that displays data using vertical bars, where the height of each bar represents a value. It is commonly used to compare discrete categories or track changes over time. The x-axis represents categories, while the y-axis represents numerical values. Column charts are useful for visualizing trends, making comparisons, and identifying patterns such as increases, decreases, or outliers within a dataset.

• Usage: 🧵 Pattern 🔍 Comparison

• Types:

  • Clustered Column Chart compares individual values across categories.
  • Stacked Column Chart compares both the total value and the breakdown of categories.
  • 100% Stacked Column Chart focuses on the percentage contribution of each sub-category, normalizing each column to 100%.

💡 See the js-chart-examples repo for many detailed examples of how to use and customize (style) different types of column charts.

Column Charts, Stacked Column Charts and 100% Stacked Column Charts require the following files to render correctly.

Column charts accept the following chart attributes.

🧱 class | 🗂️ type | 🕒 version | 📋 template | ↔️ width | ↕️ height | 📄 title | 📄 ytitle | 📄 xtitle | 📏 scalemin | 📏 scalemax | 🔄 swapaxis | 🔽 sortdata | 🚫 limitdata | 🔲 showborder | 🏷️ showlabels | 📘 showlegend | 🎮 showcontrols | 🗂️ showdatatable | #️⃣ showgridlines | ➖ showzeroline | 📲 showwidget

The js-labels input container sets the labels that anchors each cluster on the axis (e.g., different months, regions, or items).

The container accepts a comma-separated list of text values.

<div class="js-labels">label-0, label-1, label-2, ..., label-n</div>

The example below sets the category labels on a chart to the months of the year.

<div class="js-labels">Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec</div>

The js-values input container sets the individual data series (or data sets) on a chart.

The container accept a comma-separated list of numeric values.

<div class="js-values">10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120</div>

The js-values input container accepts a title attribute that is used to set a name or short description for the data series (or data set).

<div class="js-values" title="Sales revenue 2024">10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120</div>

ℹ️ A title will automatically be assigned to each data series (or data set) if no title attribute is assigned to the js-values container.

Clustered data series (or multiple data series) can be set by specifying multiple js-values input containers. Each container represents a single data series (or data set).

<div class="js-values" title="Sales revenue 2024">20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130</div>
<div class="js-values" title="Sales revenue 2023">15, 25, 35, 45, 55, 65 75, 85, 95, 105, 115, 125</div>
<div class="js-values" title="Sales revenue 2022">10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120</div>

Every chart is customized (or styled) using one of the supported style templates.

Style directives are used to override the customization applied by the style template to each chart.

Column charts support the following style directives.

🖼️ js-canvas-* 📊 js-chart-* 🎨 js-color-* 🖱️ js-control-button-* 🏷️ js-datalabel-* 🗂️ js-datatable-* 🦶 js-footer-* #️⃣ js-grid-line-* 📘 js-legend-* 🎮 js-options-menu-* 📏 js-scale-* 📄 js-title-* 🧱 js-value-bar-* ➖ js-zero-line-*

💡 See the 👀 js-chart-examples repo for many detailed examples of how to use the style directives to customize a chart.

The example below renders a clustered column chart, showing Quarterly Sales of three product lines (e.g., in a retail business).

<div class="js-chart" type="100% stacked column" template="darkweb" title="Quarterly Sales by Product Line" ytitle="Product Lines" xtitle="Sales (USD)">
	<div class="js-labels">Q1, Q2, Q3, Q4</div>

	<div class="js-values" title="Clothing (USD)">15000, 17500, 14000, 19000</div>
	<div class="js-values" title="Accessories (USD)">8000, 9200, 10500, 11000</div>
	<div class="js-values" title="Home Decor (USD)">6500, 7000, 6800, 7400</div>

	<div class="js-color-palette">Orange, SteelBlue, CadetBlue</div>
	<div class="js-datalabel-font-size">14px</div>
	<div class="js-datalabel-font-weight">600</div>
	<div class="js-datalabel-text-color">white</div>
	<div class="js-value-bar-series-margin">10px</div>
</div>

The js-labels input container sets the labels that anchor each cluster on the axis. In this example, each cluster represents one quarter in the year.

There are three js-values input containers. Each container represents one data series (or data set) on the chart. In the example, each container represents one product line.

• The js-color-palette style directive sets a list of three colors to be used on the chart. Each color is assigned to a data series (or data set) in a round robin rotation assignment.
• The js-datalabel-font-size sets a font-size of 14px for all data labels on the chart.
• The js-datalabel-font-weight sets a font-weight of 600 for all data labels on the chart.
• The js-datalabel-text-color sets a foreground color of white for all data labels on the chart.
• The js-value-bar-series-margin sets a gap of 10px between each column on the chart.
