Tips for Removing Numbers from a Doughnut Chart in ChartJs 2 upon Initialization

I am currently struggling with a doughnut chart that is displaying data numbers on the chart segments upon loading, making it appear cluttered. I have attempted to remove these labels using the following code:

Chart.defaults.global.legend.display = false;

However, this only removes the legend and not the actual labels on the chart.https://i.sstatic.net/zUF3F.png

My questions are: 1) How can I clean up the chart by removing these data labels? 2) As shown in the provided image, the chart appears to be cropped on the left and right sides. Despite checking the canvas width and height, there seems to be extra space available. Why is the chart being cropped like this?

Answer №1

When using Chart.js, data labels are not drawn by default. If you see data labels on your chart, it is likely that you have enabled a plugin such as chartjs-plugin-datalabels to display them.

If you want to disable a global plugin for a specific chart instance, you can set the plugin options to false.

For example, if you are using the chartjs-plugin-datalabels, you can disable it like this:

options: {
  plugins: {
    datalabels: {
      display: false
    }
  },
}

To prevent cropped data labels, you can add extra space to the left and right of the chart using the layout.padding option as shown below:

options: {
  layout: {
    padding: {
      left: 50,
      right: 50
    }
  }
}
