Chart.js Mixed Chart Types

Last Updated : 28 Apr, 2025

Chart.js mixed Chart Type is a single graphical representation in which multiple chart types are combined. Examples are line, bar, radar, and doughnut in a single chart. It will help to differentiate data with proper visualization. In this article, we will learn about the Mixed Chart Types in Chart.js.

NOTE: When creating a mixed chart, we specify the chart type on each dataset.

Syntax

new Chart(document.getElementById("chartID"), {
    type: 'bar', // primary chart type
    data: {
        labels: ['Label1', 'Label2', 'Label3'],
        datasets: [{
            type: 'line', // specifying a different chart type
            data: [value1, value2, value3],
            // additional line chart configurations
        }, {
            type: 'bar', // another chart type
            data: [value4, value5, value6],
            // additional bar chart configurations
        }]
    },
    options: {
        // chart options
    }
});

Drawing Order:

The default drawing order of datasets is such that the first one is displayed at the top. This order can be changed by specifying the "order" option for datasets, which defaults to 0.

Example 1: In this Example, we will combine Line and Bar Charts. Bar chart is showing the numericals values and similary the line chart is also showing the numberical values.

                    backgroundColor: 'red'

Example 2: In this Example, Line and Radar Chart will be combined. The radar chart segment displays data on activities like Eating, Drinking, Sleeping, and Designing, while the line chart segment overlays this with a separate set of data points, allowing for a multi-dimensional analysis of the given information.
