@nightingale-elements/nightingale-track-canvas v5.6.0

nightingale-track-canvas

Alternative to nightingale-track, using HTML canvas for rendering instead of SVG graphics.

Canvas-based rendering can provide better performance, especially with large datasets (many features within a track or many parallel tracks). Some non-critical parts are still implemented via SVG (e.g. highlights).

Application interface for nightingale-track-canvas is the same as for nightingale-track. Some shapes might look slightly different. In case there are overlapping features, their order (z-index) might not be preserved.

Usage

<nightingale-track-canvas 
  id="my-track-id"
  length="223"
  height="100"
  display-start="1"
  display-end="50"
  layout="non-overlapping"
></nightingale-track-canvas>

Setting the data through property

const track = document.querySelector("#my-track-id");
track.data = myDataObject;
