#lightningchart #fintech #trader #javascript

Hey, I'm Omar, and this time I wanted to bring you some good news about the latest release of LightningChart JS Trader 3.1.

LightningChart JS Trader is a high-precision chart suite for creating next-gen financial & trading applications.

In this release, we focused on adding quality-of-life improvements and bug fixes. Here are some of the changes:

NPM Registry

Starting with version 3.1, LightningChart JS Trader is available for download from the public NPM registry. Previously, it was distributed via separate files sent by email.

A valid license key (trial or purchased) is still required to use the library. Older versions will not be published on NPM. With this change, we are simplifying both updates and trial downloads.

Transparent chart

You can now set the chart to use a transparent background, making it easier to match the application’s background. Here is an example of a chart with a transparent background. The colors come from the underlying div-elements:

Mountain gradient

The Mountain chart type can now be colored using a gradient fill. The coloring is based on the current line color and the enableMountainGradient() method can be used to switch the gradient on and off.

Other library improvements

Time range methods
HTML text rendering
Menu options
Clear everything method

Bug fixes and improvements

Problem with the space bar not closing menus anymore when typing in the input fields
The menus work better now when the chart height is small
Color pickers now appear next to the color button instead of the top-left corner.

However, note that Firefox browser has still some issues with this. Furthermore, the default color in the color pickers now matches the current color in all cases.

We also improved the accuracy of the data cursor and the Zoomband chart height is now based on the main chart’s height, allowing it to scale better.
