LightningChart Ultimate v.8.2
NEW FEATURES
1. Headless mode
The headless mode allows LC to be used without GUI e.g. in Windows Services and on Console
applications. Example use case is generating chart pictures for reports or web pages.
In headless mode, the chart frames are captured as images. The bitmaps can be acquired e.g.
by utilizing
• OutputStream property
• SaveToStream method
• CopyToClipboard method
• CaptureToByArray method
• SaveToFile method

LightningChart Ultimate v.8.2
NEW FEATURES
The service can be set running e.g. in a local network server or a Windows Server
running in a cloud.
In inter-process communication, between Windows Application and Windows
Service, e.g. Named pipes or Socket I/O communication can be used.
There is a new Headless mode demo solution included in the SDK. It uses Windows
server on the local computer. WPF application takes a connection to it with Named
Pipes and shows the image stream the service sends.

2. BaseLevel in ViewXY’s BarSeries
BaseLevel property added in BarSeries is a series minimum value for all series values and
tells bar start position. In Stacked view, it will increase (if positive) or decrease (if negative)
the size of the bar. If StackedToSum, the bar size is relative and calculated like Stacked.
BaseLevel set to 100. Bar values are 10, 20, 35, 50, 58, 45, 30, 25, 20, 5.
In previous LightningChart versions, the bars work like the BaseLevel was set to 0.

3. MeshModels programmatical construction
MeshModel supports constructing the MeshModel geometry programmatically. It allows
visualizing objects and shapes that have been produced as a result of computation.
The following Create methods are available
• Create(positions, colors, indices)
• Create(positions, colors, normals, indices)
• Create(positions, textureCoordinates, bitmap, textureWrapMode, indices)
• Create(positions, normals, textureCoordinates, bitmap, textureWrapMode, indices)
Index array (indices) parameter is optional for all methods. If provided they will define which
vertices, colors, light normals and texture coordinates to use from the arrays given. Using
indices saves resources when same vertices are shared between multiple triangles.
MeshModels constructed by code.
The rotation, scaling and positioning properties etc., as well as events, apply also for a
MeshModel created programmatically from vertices, in a similar way they work for loaded
objects.

6. Controlling visibility of Intensity and Surface series palette scale in
legend boxes.
The palette scale can be hidden by setting LegendBox.IntensityScales.Visible to ‘False’ (in
ViewXY) and LegendBox.SurfaceScales.Visible to ‘False’ (in View3D).
LegendBox.IntensityScales.Visible = ‘False’ in the picture in the bottom.
