By setting the property type to 'bar' or 'line', you can combine the values of all datasets into a single bar or line chart. Additionally, you can use the data property to specify the values for the combined dataset. This will allow you to display the total value of all datasets in the graph. You can also customize the appearance of the combined dataset by setting properties such as color, border width, and label.

How to create a scatter plot in chart.js?
To create a scatter plot in Chart.js, you can follow these steps:
- First, include the Chart.js library in your HTML file. You can download it from the Chart.js website or use a CDN link. For example:
- Create a canvas element in your HTML file where you want to display the scatter plot. Give it an id so you can reference it in your JavaScript code. For example:
- Write JavaScript code to create the scatter plot using Chart.js. First, get a reference to the canvas element and create a new Chart object with type 'scatter'. Then, define the data and options for the scatter plot. For example:
var ctx = document.getElementById('scatterChart').getContext('2d'); var scatterChart = new Chart(ctx, { type: 'scatter', data: { datasets: [{ label: 'Scatter Plot', data: [ { x: 10, y: 20 }, { x: 15, y: 25 }, { x: 20, y: 30 }, // Add more data points here ], backgroundColor: 'blue' }] }, options: { scales: { x: { type: 'linear', position: 'bottom' }, y: { type: 'linear', position: 'left' } } } });
- Customize the scatter plot by adding more data points, changing the colors, labels, and other options as needed. You can also add multiple datasets for more complex scatter plots.
