apexcharts 8.1.0

💎 Version 8.1.0

on Node.js NPM

Weave plugins can now draw a part of each value with api.highlight(), the way the highlight filter does, instead of adding a series.

The rest is a fix release from a full audit of the 8.x code: about 100 fixes to updates, tooltips, data parsing, legends, exports, gauges and server rendering. A few change behaviour you may rely on:

Update calls on a destroyed chart now warn and resolve instead of throwing, and render() after destroy() works. CSV export writes one row per category for OHLC and range series, and the time of day when two datetime categories share a day.

✨ New

• Let a plugin draw a part of each value instead of adding a series.
