Announcing LightningChart .NET 12.5.1

Source: Dev.to

LegendBox Improvements

We have refined LegendBox rendering to harmonize all XY, 3D, Polar, Pie3D, and Smith views. New features include:

• VerticalTitlesGap property – controls the minimum gap between titles.
• Support for titles with multiple lines.
• Mouse events over the LegendBox now provide more detailed information.

Below is an example of LegendBoxes with multiple‑line titles, showing a normal versus a reduced vertical gap.

PrintPreview Dialog Improvements (WinForms)

The PrintPreview dialog is now available in several languages, including English, German, and Finnish. The printing dialogue UI has been slightly changed, allowing users to:

• Control which items to show.
• Set default values for those items.

Below is an example of the improved PrintPreview dialog window.

ViewXY AutoPadding

A new AutoPadding property has been added to ViewXY. It defines padding for PXs that controls edges such as outer edges or the rim of a chart, which encloses ViewXY margins.

• AutoPadding works when margins are auto‑adjusted (AxisLayout.AutoAdjustMargins is enabled).
• Chart objects like Annotations and LegendBoxes can be placed in the padded area.
• In WinForms, AutoPadding is a padding structure; in WPF, it is a thickness structure.

Below is a simple ViewXY.AutoPadding example where the padded area is pseudo‑colored differently (in grey) for clarity, with the help of an Annotation.

.NET Trader Improvements

• Band’s border now supports three BorderType options: Inner, Outer, and None.

Additional Improvements

• Added support for 24‑bit and 32‑bit WAV audio files.
• Improved handling of D3DImage failures.
