Detailed Description

Entity for plotting raw data points as a connected polyline.

Stores a vector of raw (x,y) points and draws straight line segments between them. Each segment is rendered using the current line style (Solid, Dashed, Dotted), with configurable color, thickness, dash length, and gap length.

Note

Unlike FunctionEntity, this class does not evaluate a function — it directly uses the provided data points. The points are still transformed by the entity's origin and scale before rendering.

Sets the line thickness in pixels.

Parameters

thickness

Line width.

setLineStyle()

void wPlot2D::DataPlotEntity::setLineStyle

(

wEngine::LineStyleComponent::LineStyle

style
