Performance

Chart.js charts are rendered on canvas elements, which makes rendering quite fast. For large datasets or performance sensitive applications, you may wish to consider the tips below:

• Set animation: { duration: 0 } to disable animations.
• For large datasets:
  • You may wish to sample your data before providing it to Chart.js. E.g. if you have a data point for each day, you may find it more performant to pass in a data point for each week instead
  • Set the ticks.sampleSize option in order to render axes more quickly
