LightningChart JS v.4.1 has been released!

Adding new product features, visual quality and performance improvements, and more.

Introducing dashed Lines

We’ve been listening closely to your feedback and are thrilled to announce that we’re now introducing dashed line patterns available for line-based series, gridlines, and constant lines.

An example use-case for dashed lines is, e.g., when comparing two types of values using solid lines for certain data and dashed lines for uncertain data.

Custom ticks in 3D charts

You can now manually place custom ticks within 3D charts. You’ll likely use this new feature in the following cases:

Whenever a user needs a tick to be placed at a specific location.
When using the categorical axis.

	.getDefaultAxisZ()
	.addCustomTick()
	.setValue(1)
	.setTextFormatter((_) => 'Category 1')

Flat themes & No-code editor

Flat color themes are simple yet elegant color variants that are now available as open-source which you can access in GitHub.

Flat themes examples

We have decided to make our flat themes available as open-source for those users who would like to use them as a reference for creating their own themes. This can help you develop a custom theme faster than starting from scratch.

No-code Themes Editor

In addition to the open-source flat themes, we’re releasing a free-to-use no-code Themes Editor that will help you fasten the creation of a custom theme, quickly modify fonts and colors, and directly export it to your application.

Visual improvements on MapChart

In LightningChart JS v.4.1 regions in a map chart can now be individually highlighted on hover.

Other Improvements

Performance has been an important topic in this new LightningChart JS v.4.1 release, especially for map charts:

We’ve improved to loading speed to 5x faster from 250ms to 50 ms.
CPU consumption in stress testing has been reduced to 15x less than previously.
The GPU consumption has been reduced to half.
